Doepke DOEP DFS4 063-4/0,50-A S Residual current circuit breaker DFS4 4-po

The Doepke DFS4 063-4/0.50-A S residual current circuit breaker is a highly advanced safety device designed to protect people, animals, and electrical systems. This residual current circuit breaker (RCCB) cuts off the power supply when dangerously high fault currents are detected. It is available in a compact design and is suitable for both single-phase and three-phase networks. With high immunity to surge fault currents and network voltage-driven follow-up current impulses, it provides reliable protection in various applications. The type A tripping characteristic ensures sensitivity to pulsating and alternating currents, making it particularly versatile. The integrated labeling software facilitates easy labeling, while the large double-deck terminals allow for simple installation and connection of large conductor cross-sections. The switch is designed for mounting on a DIN rail and offers a response delay for selective versions, making it ideal for complex electrical systems.

• Two or four-pole design for flexible applications
• High immunity to surge fault currents
• Network and auxiliary voltage-independent tripping
• Easy fault diagnosis through the tripped position of the multifunction switch knob
• Suitable for monitoring circuits with 230 V and 400 V.
