Abb xt4encl250r Nema 3R Enclosure Tmax XT4

Product Description

The ABB xt4encl250r is a NEMA 3R-rated surface-mount enclosure designed for use with the Tmax XT4 series molded-case circuit breaker. The NEMA 3R rating means the enclosure is built to protect interior components from falling rain, sleet, and ice formation, making it suitable for outdoor or wet-location installations. Electrical contractors and industrial electricians install this enclosure to house and protect the XT4 breaker in surface-mounted applications where conduit entry and environmental protection are required. It provides a code-compliant housing solution wherever the Tmax XT4 is deployed outside of a panel or switchboard.

This enclosure is used in both commercial and light industrial electrical systems where the Tmax XT4 molded-case circuit breaker is installed as a standalone disconnect or branch-circuit protective device. Surface-mount installation suits applications where flush or recessed mounting is not practical, such as on exterior walls, mechanical rooms, or rooftop equipment installations exposed to weather. It is appropriate for use in facilities requiring outdoor-rated electrical enclosures per applicable electrical codes.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit completely before mounting the enclosure or making any wiring connections. Ensure all conduit entries are properly sealed with listed fittings to maintain the NEMA 3R rating after installation. Verify mounting surface integrity and use appropriate hardware rated for the enclosure weight and environmental conditions.
