The purpose of circuit breakers is to automatically switch off circuits to protect cables and connected devices. After a switch-off, they can be switched on again manually without, for example, having to replace fuse inserts. Each of our circuit breakers is equipped with a trip-free mechanism that ensures safe switching off, even if, for example, the switch knob is mechanically blocked. Circuit breakers in the DMCB 2 series have a high short-circuit switching capacity of up to 25 kA. They can accommodate large conductor cross-sections. Their switchgear is designed as a double breaker and has isolating properties. Switches with tripping characteristics C are optimized for power circuits with high inrush or peak currents. Properties: high short-circuit switching capacity, U-shaped terminal on both sides for large conductor cross-sections and busbars, switch position indicator, mounting type: quick attachment to mounting rail, installation position as desired, areas of application: suitable for use in power supplies for industrial plants and purpose-built or commercial buildings.
