Overview
The Carling Switch DA2-B0-46-625-121-C is a D-Series 2-pole hydraulic-magnetic circuit breaker engineered for high-current industrial applications. With a 25A rating across 480VAC and 277VAC systems (150VDC capability), this breaker combines thermal-magnetic protection with hydraulic delay characteristics to minimize nuisance trips while ensuring fast fault clearance. Panel-mount construction makes it suitable for motor control centers, distribution panels, and industrial machinery protection.
