Carling - Model B-Series -Hydraulic-Magnetic Circuit Breaker
The B-Series are an optimal choice for both general purpose and full amp load applications. Extra insulation delivered by the tongue & groove half-shell construction provides the necessary spacing requirements for global regulatory safety approvals. Actuator options include handle, mid-trip handle, rocker and flat rocker. Rocker actuator options can be single color or a two color Visi Rocker®, both with push-to-reset options and choice of horizontal or vertical styling. Adding to the breaker’s versatility is a comprehensive choice of circuits, time delays, terminals and imprinting options. The B-Series is available as a one to six pole handle breaker or a one to three pole rocker breaker.
