Miniature Circuit Breaker (MCBs)

Circuit-breakers, Characteristic B, C, D, 6-32 A, 6 kA, for commercial sector applications

Circuit-breakers, Characteristic B, C, D, 0.5-63 A, 10 kA, for industrial facilities

Function

The task of miniature circuit breakers is to automatically disconnect circuits in order to protect lines and connected devices. After disconnection, they can be manually reactivated without the fuse sets having to be replaced, for example. Each of our miniature circuit breakers is equipped with a trip-free mechanism, which guarantees safe deactivation even if, for example, a switching knob is mechanically blocked. The DLS 6 miniature circuit-breaker variant protects cables, lines and installation devices from overload and short-circuits as laid down in DIN VDE 0100. The variant comprises a large selection of different types for switching in residential and purpose-built buildings, and for industrial applications. Its compact design means the DLS 6 miniature circuit-breaker provides maximum space for ease of wiring. The large clamping area and ability to use commercial wiring rails ensure simple installation. It is also possible to connect a number of additional devices such as operating current trip and auxiliary/fault sensors. The DLS 6h variant for skilled trade is suitable with its rated switching capacity of 6 kA for distributor and final circuits. Switches with tripping characteristic C are optimised for power circuits with high inrush or peak currents.
