The AA2-B0-22-630-1B1-C is a two-pole hydraulic-magnetic circuit breaker designed for general-purpose and full-load applications in compact panel-mount configurations. It is rated for a maximum current of 50 A at 277 VAC (50/60 Hz) or 80 VDC, with a maximum interrupting capacity of 7,500 A and operates with a series trip (current-sensing) coil configuration. The breaker features a sealed toggle actuator suitable for harsh environments and includes tab-type quick-connect terminals for reliable electrical connections. It is available with optional auxiliary SPDT alarm switches and supports multiple delay characteristics (instantaneous, medium, or long delay) for flexible protection schemes. Common applications include marine systems, renewable energy installations, industrial automation, welders, generators, and commercial food equipment where reliable overcurrent protection and compact design are essential.
