SURGE TRAP

SURGE TRAP is a brand of surge protective devices (SPDs) designed for industrial and commercial electrical systems. The product line available through 3G Electric focuses on chase-nipple external-mount SPDs, which are installed directly into electrical enclosures via a threaded chase nipple, eliminating the need for separate conduit runs. These devices are housed in polycarbonate enclosures rated NEMA 4X, providing resistance to corrosion, moisture, and dust ingress, making them suitable for outdoor or washdown environments. The SPDs cover a range of common voltage configurations: single-phase 120 V AC, 120/240 V AC, and 240 V AC; three-phase wye configurations at 120/208 V AC, 277/480 V AC, and 347/600 V AC; and three-phase delta configurations at 240 V AC and 480 V AC. Each unit is rated for a maximum surge current of 50 kA per mode, with voltage protection ratings (VPR) varying by model—for example, 1800 V for most wye configurations and up to 3000 V for 480 V delta. The maximum continuous operating voltage (MCOV) is specified per model, such as 150 V AC for 120 V systems and 550 V AC for 480 V delta systems. These SPDs are intended for use in main service panels, distribution boards, and equipment-level protection in facilities such as manufacturing plants, water treatment facilities, and commercial buildings. 3G Electric stocks multiple SKUs across this family, providing datasheets and logistics support for procurement specialists and engineers specifying surge protection for new installations or retrofits. The brand does not appear to have a widely documented corporate history; the available information is limited to the product specifications and typical applications of the SPDs themselves.

Each unit is rated for a maximum surge current of 50 kA per mode, with voltage protection ratings (VPR) varying by model—for example, 1800 V for most wye configurations and up to 3000 V for 480 V delta.

Frequently asked questions

Common questions about SURGE TRAP from 3G Electric.

What voltage configurations are available in the SURGE TRAP STXR series?

The SURGE TRAP STXR series includes models for single-phase 120 V AC, 120/240 V AC, and 240 V AC; three-phase wye at 120/208 V AC, 277/480 V AC, and 347/600 V AC; and three-phase delta at 240 V AC and 480 V AC. Each model is designed for a specific system voltage and MCOV, as listed in the datasheets.

What is the enclosure rating of SURGE TRAP chase-nipple SPDs?

The SURGE TRAP STXR series SPDs use a polycarbonate enclosure rated NEMA 4X. This rating provides protection against corrosion, rain, sleet, snow, and hose-directed water, making the units suitable for outdoor or damp industrial environments.

What is the maximum surge current capacity of SURGE TRAP STXR models?

Each SURGE TRAP STXR model is rated for a maximum surge current of 50 kA per mode. This rating applies to all modes of protection (line-to-ground, line-to-neutral, neutral-to-ground, and line-to-line where applicable), as specified in the product datasheets.

How are SURGE TRAP SPDs installed?

SURGE TRAP STXR series SPDs are external-mount devices with a chase-nipple connection. The unit is threaded directly into a knockout on the electrical enclosure, allowing for a secure, weathertight installation without additional conduit. Wiring connections are made inside the enclosure.

What is the voltage protection rating (VPR) for the SURGE TRAP STXR480Y05N?

The SURGE TRAP STXR480Y05N, a three-phase wye model for 277/480 V AC systems, has a voltage protection rating of 1800 V for all modes: H-G, H-L, L-G, and L-L. This VPR indicates the let-through voltage under standard surge conditions.

Does 3G Electric supply SURGE TRAP products?
