Surge protective device · 120/240V AC Type 2 108 kA NEMA 4 · Eaton CHSPT2ULTRA

SKU: EAT-CHSPT2ULTRA

Type 2 surge protective device for 120/240V AC single-phase service entrance or panel protection in residential and light commercial electrical systems. Rated 108 kA surge current with a NEMA 4 enclosure; typically installed as a whole-home or whole-panel SPD by a qualified electrician.

What this product is for

The Eaton CHSPT2ULTRA is a Type 2 surge protective device for 120/240V AC single-phase electrical systems. It is used at the service entrance or distribution panel to help limit transient overvoltage reaching connected equipment such as appliances, electronics, controls, and other branch-circuit loads.

Use for

Use for residential homes, cottages, and light commercial buildings with 120/240V AC single-phase service. Suitable where a panel-mounted or externally mounted SPD is needed with a NEMA 4 enclosure, cUL certification, and UL 1449 compliance.

Avoid for

Avoid using this device on systems outside its 120/240V AC single-phase rating, or where a different SPD type, voltage configuration, or enclosure requirement applies. Do not treat a whole-panel SPD as a substitute for point-of-use protection on highly sensitive electronics where layered protection is required.

Best for

Best for electricians and contractors specifying whole-home or whole-panel surge protection on split-phase 120/240V services. Also a practical choice where outdoor or damp-location mounting conditions call for a NEMA 4 enclosure.

Installed in

Typically installed at or beside the main panel, meter-main, or service equipment by a qualified electrician. The enclosure measures approximately 7 in x 5 in x 2.5 in (178 x 127 x 64 mm), which helps when planning panel-adjacent mounting space and conductor routing.

Why this product exists

This SPD is designed to divert surge energy from lightning-related events, utility switching, and internal load switching before it reaches downstream equipment. In trade use, whole-building surge protection is commonly paired with point-of-use protection for sensitive electronics as part of a layered protection approach.

Compared with similar products

Compared with basic plug-in surge strips, this Type 2 SPD protects at the panel level and covers the electrical system more broadly. Compared with lower-rated SPDs, the CHSPT2ULTRA offers 108 kA surge current capacity, 20 kA nominal discharge current, and a NEMA 4 enclosure for more demanding installation conditions. Actual protection performance depends on installation layout, lead length, grounding, and local electrical code.
