Eaton CHSPT2SURGE Whole Home Surge Protector 120/240V

Designed for residential and light-commercial electrical panels, this Eaton SPD (surge protective device) provides AC power line protection with a weatherproof NEMA 4 enclosure and easy quick-connect installation. It connects on the load side of the main disconnect and is compatible with most manufacturers' load centers, helping divert harmful voltage spikes away from appliances and electronics.

How does the Eaton CHSPT2SURGE protect my home's electronics?

The unit diverts transient overvoltages by channeling surge energy to ground before it reaches downstream circuits. Its ratings — including a 5 kA nominal discharge current and a 22 kA surge current capacity — indicate the device's ability to handle common surge events.

• Nominal discharge current (In): 5 kA
• Total surge current capacity: 22 kA
• Per-phase surge distribution: 36 kA combined (L1–N 18 kA, L1–G 18 kA, L2–N 18 kA, L2–G 18 kA)
• Voltage protection ratings: 600 V L–N, 1000 V L–L, 800 V N–G, 600 V L–G

Where and how should this surge protector be installed?

Install the Eaton CHSPT2SURGE on the load side of your load center's main service disconnect, mounted to the panel exterior if needed. It requires connection through a dedicated circuit breaker and should follow NEC installation guidelines.

• Mounts outside any manufacturer’s load center or directly to the panel
• Connect on the load side of the main service disconnect via dedicated breaker
• Quick-connect design simplifies attachment of cable protection modules
• Follow local electrical codes and NEC recommendations when wiring

What are the electrical and environmental specifications I should know?

This SPD is built for single-phase 120/240 VAC systems at 60 Hz and has a durable NEMA 4 housing for damp and splash-prone locations. Maximum continuous operating voltage and protection levels are provided to match typical residential distribution voltages.

• Rated voltage: 120/240 VAC, single-phase, 60 Hz
• Maximum continuous operating voltage (MCOV): 150 V L–N, 300 V L–L
• Enclosure rating: NEMA 4 (splash- and dust-resistant)
• Meets UL 1449 Third Edition requirements for surge protective devices

How will I know if the surge protector is functioning?

A built-in LED status indicator provides a quick visual check of the SPD’s operational state. Regular visual inspection helps confirm protection is active; replace the unit when status indicates failure or after a major surge event per product guidelines.

• LED status indication for operational verification
• Visual checks recommended after storms or major electrical events
• Replace or service according to Eaton guidance if LED indicates a fault

Who is this for: The Eaton CHSPT2SURGE suits homeowners, electricians, and small business operators who need a robust, panel-mounted Type 2 surge protector for 120/240V single-phase systems. It is ideal when you want an easy-to-install, weather-resistant SPD that integrates with most breaker boxes and offers clear status feedback for routine maintenance.
