An important stipulation of DIN VDE 0100 is to protect cables, lines and installation devices from overload and short-circuits. This requirement can be met using miniature circuit-breakers (MCBs). In industrial installations and also in commercial buildings, they often take on additional protection of equipment and devices where there are usually higher requirements than when used in residential buildings. Miniature circuit-breakers utilise both the magnetic and heat effect of the electrical current. If the current jumps to a value that is too high when a short-circuit occurs, the MCB interrupts the circuit using the magnetic field of an energised coil. The heat that develops when there is continuous overload causes the bimetal to warp, which trips the breaker. The miniature circuit-breaker series DLS 6 has a wide selection of different types for a number of application areas. In addition to switches for residential and purpose-built buildings, it also contains switches for industrial applications. The compact design provides lots of space for the wiring and the large clamping area, as well as the option of using conventional wiring rails for easy processing. The series also has a large, folding label window and a clearly labelled display for the operating status.
