This easily installed and serviceable unit incorporates a Type QMS transformer (single-phase) or a Type QL transformer (three-phase), a primary main circuit breaker, a secondary main circuit breaker and a load-center-design breaker panel. Since these components don't have to be installed and interconnected separately, the contractor or user can reduce installation time and costs. Because of the single-unit concept, only one, handy Service center needs to be mounted. Keyhole mounting flange facilitates easy Mounting-Indoor and outdoor Use-Front - accessible, hinged or removable panel door-Heat barrier under core and coil provides added electrical and thermal isolation for wiring compartment-High-efficiency core construction-Factory installed and wired GE main and secondary main circuit breakers-Transformer, distribution panel and breakers are all designed, built and assembled by GE 21S1100.
