Carling Technologies DA1B034450121C D-Series Circuit Breaker

The Carling Technologies D-Series circuit breaker offers a robust solution for industrial applications requiring snap-on rail mounting. Designed for 35mm x 7.5mm or 35mm x 15mm symmetrical DIN rail mounting, it allows for rapid and simple installation and removal. Key features include recessed, wire-ready, touch-proof terminals, suitable for automatic screwdriver assembly, and “Dead Front” construction. The Visi-Rocker actuator provides clear visual indication of the breaker's status, enhancing safety and operational awareness. Common trip linkage ensures that an overload in one pole trips all adjacent poles, providing comprehensive protection. This circuit breaker is ideal for industrial controls, renewable energy systems, and other demanding environments.
