Schurter AS168X-CB2DH150 Thermal Magnetic Circuit Breaker

Schurter AS168X-CB2DH150 Thermal Magnetic Circuit Breaker is a two‑pole, four‑terminal protective device from the AS168X TM family, designed to safeguard electrical circuits from both overloads and short circuits. The DH150 variant carries a 30 A nominal rating, identified in its order number 420.0394, and is part of the CB2H/DH line differentiating current ratings within the AS168X range. As a thermal-magnetic breaker, it employs a thermal overload element for gradual overcurrent protection and a magnetic element for rapid trip during fault conditions, providing reliable circuit protection in equipment and control panels. The CB2 designation confirms two poles, while the four terminals support straightforward line and load connections in compact installations. This model is commonly considered for use in motor controllers and other industrial or commercial equipment, aligning with Schurter’s emphasis on robust protection for power electronics and control systems.
