Circuit breaker DPX³ 160 - thermal-magnetic release - 16 kA - 400 V~ - 4P - 160 A 420017 Legrand

• PURPOSE Circuit breaker is a mechanical switching device capable of making, carrying, and breaking currents under normal circuit conditions, as well as making, carrying for a specified time, and automatically breaking currents under specified abnormal circuit conditions, such as short-circuit currents. • APPLICATION Used in low-voltage electrical networks for switching and protecting electrical networks and devices for various purposes. • PRINCIPLE OF OPERATION Switching on-off is performed by a lever; wires are connected using bolt or screw connections. The circuit is switched by moving and stationary contacts. The moving contact is spring-loaded; the spring provides the force for rapid contact separation. The trip mechanism is actuated by one of two trip units: thermal or magnetic. • ADDITIONAL ACCESSORIES OR ACCESSORIES The standard configuration includes the product itself
