Square D J250AWK Circuit Breaker Enclosure 15-250A

Product Description

The SQUARE D J250AWK is a circuit breaker enclosure designed to house and protect H Frame and J Frame circuit breakers rated from 15 to 250 amps. Built for electrical distribution applications, this enclosure provides a secure mounting and protective housing for the breaker assembly, keeping internal components shielded from contact and environmental exposure. At 32.8 inches in length, 9.6 inches in width, and 8 inches in height, it accommodates the physical footprint of full-frame molded case breakers. Electricians and electrical contractors install this enclosure in commercial, industrial, and residential service applications where a standalone breaker enclosure is required.

This enclosure is suited for use in panelboard, switchboard, and disconnect applications where an H Frame or J Frame molded case circuit breaker needs a dedicated enclosure. It is appropriate for new installations and replacement service work. The size range of 15 to 250 amps covers a wide range of branch and feeder circuit applications, making it a practical fit for both light commercial and heavier industrial electrical systems.
