A shortlist for discussion, not a universal winner.
The examples below use manufacturer documents for the named model or generation. They are not interchangeable simply because they are sold as whole-home surge protection. Availability, panel compatibility and suitability must be confirmed for the proposal.
We do not assign scores or imply manufacturer endorsement, dealer status or guaranteed availability.

Manufacturer specifications02 / Device & Warranty Comparison
Read the numbers on the same basis.
Surge-current capacity, measured in kA, is not the same as nominal discharge current (In). Per-phase, per-mode and unspecified headline values should not be compared as if they describe the same test or total.
VPR is a standardized voltage protection rating for a specified mode, such as line-to-neutral. Lower values in the same mode can be useful to compare, but a single VPR does not describe installed performance under every surge. Connection length and routing also matter: unnecessarily long or looped leads can increase impedance. The installer follows the exact connection instructions; this is not a homeowner wiring task.
SCCR describes short-circuit suitability. It is not a surge-capacity score. MCOV concerns the voltage that can be applied continuously; it does not make an SPD a sustained-overvoltage remedy. The installer verifies these requirements for the actual system.

VPR: compare each electrical path.
These values are in volts and come from the cited manufacturer documents. LN means line-to-neutral; LG line-to-ground; NG neutral-to-ground; LL line-to-line. They are specification comparisons, not a prediction of the voltage reaching your appliance in a particular event.
Notice that the HD2 and HD do not sort into the same order for every mode. That is why a simple claim that one model always clamps better would be misleading.
| Model | LN | LG | NG | LL |
|---|---|---|---|---|
| VR1-120-4XM | 700 | 700 | 700 | 1,000 |
| DTK-120/240HD2 | 600 | 600 | 900 | 1,000 |

The best fit includes the installation.
For these residential examples, confirm the intended 120/240-volt system, mounting environment, equipment compatibility, available fault current and the exact current instructions. An outdoor-rated enclosure still needs an appropriate installation; a NEMA enclosure rating is not permission to submerge a device.
Type 1 and Type 2 are not quality grades. The permitted connection location, required protection and utility restrictions determine the appropriate use. A Type 1 device is not automatically approved for a utility’s meter enclosure.
Breaker-format alternatives also need model-specific panel approval. A device that fits certain 1-inch panels does not thereby fit every Square D family, for example. The appearance of the breaker opening is not enough.
Other models may be considered after their current instructions and terms are checked. Do not substitute a look-alike product or assume that an older series has the ratings or warranty of a new generation.

05 / Device & Warranty Comparison
Separate device replacement from damaged-equipment claims.
A product warranty addresses the surge device itself. A connected-equipment program may reimburse eligible damage under separate conditions. The headline cap is a ceiling, not an automatic payment, insurance policy or assurance that lightning damage will be covered.
The condensed terms below are a starting point. The manufacturer’s full documents and the terms applicable to the purchased unit control. Obtain those documents with the proposal and keep the invoice, model and installation information.
| Model / program | Published headline terms | Limits that change the decision |
|---|---|---|
| Vortexx Series R | Lifetime product term; connected-equipment household cap $100,000 | Schedule 1 also limits each item to $1,000 for the lifetime term. Conditions include other incoming paths, eligible damage and claim evidence. |
| DITEK HD2 | 10-year product term; $25,000 residential connected equipment for 5 years | Separate connected-equipment policy includes ownership and coordinated-protection conditions. Confirm the policy applicable to the current 5th Edition product. |
| DITEK HD | 10-year product term; $10,000 residential connected equipment for 5 years | The HD2 headline cap must not be applied to the HD. Other paths and equipment may require additional specified protection. |
| Eaton CHSPT2ULTRA | Limited lifetime product and up to $75,000 connected-equipment terms | Original-owner and installation conditions apply. All relevant incoming connections must meet the policy’s protection requirements. |

Read the exclusions before the dollar amount.
The cited connected-equipment programs exclude direct or nearby-lightning situations as defined in their respective terms and sustained overvoltage conditions such as an open neutral. Coverage may be secondary to insurance or limited by a deductible. Diagnosis, removal, labor and shipping can remain the homeowner’s responsibility.
RectorSeal’s statement uses a 15-day initial notice requirement and a subsequent 30-day return deadline after the applicable return instructions. Its Series R connected-equipment provisions include a per-item cap and requirements for external signal paths. Review both the general statement and Schedule 1.
DITEK’s separate residential policy includes a 30-day claim notice requirement and coordinated protection conditions covering panel protection, appropriate Type 3 protection for electronics, signal paths and local protection for specified equipment. The policy text references an earlier UL edition while the current data sheets identify 5th Edition products; get written confirmation of the terms applicable to the proposed unit.
Eaton’s linked warranty uses a 30-day notice requirement and conditions concerning ownership, installation, protected connections and other recovery. Do not discard a damaged SPD or equipment before obtaining claim instructions. Preserve the evidence without handling unsafe equipment.

In Simple Terms
A surge protector can have several impressive numbers on its label, but they answer different questions. One describes a surge test. Another describes short-circuit suitability. Another describes the voltage rating for a particular path. Bigger is not automatically better, and numbers measured on different bases do not make a fair ranking.
Start with whether the product fits the home’s electrical system and can be installed correctly. Then consider features you can use, such as an indicator you can see or an alarm you can hear. A device that quietly reaches the end of its protection is not much help if nobody knows to ask about it.
Read a warranty as two separate conversations: what happens if the protector fails, and what happens if an appliance is damaged. A large household cap may have a much smaller cap per appliance. The program may also require other protection, quick notification and proof that the damage qualifies.
You can ask us to put the exact model, the work included and the applicable warranty documents in the proposal. That gives you something concrete to compare without needing to become an electrical engineer.
Your questions, answered.
Which brand is best?
There is no single supported winner for every home. Compare exact models, installation suitability, visible status features and the terms you can actually meet.
Does 120 kA always beat 100 kA?
Not by itself. First establish whether the numbers are per phase, per mode or another advertised basis. Surge-current capacity is only one specification and does not replace correct installation.
Is the advertised equipment warranty guaranteed coverage?
No. Eligibility, event exclusions, protection of other paths, evidence, per-item limits, insurance and deadlines can determine whether a claim is payable. Read the full terms for the exact model.
