SelectivityIn the main power supply system, the new TAB also requires the distribution system operators as well as current DIN standards. A selective overcurrent protection device is now an indispensable part of a comfortable and safe electrical installation.Super-fast installationAn innovative switching concept and the comfortable connection technology form the basis for compact design and space-saving installation. All necessary functions of the main circuit breaker are integrated and can be implemented without accessories. Feeding the external conductors directly via the LSHU-KL without additional busbar terminals saves material and space.Special lockingThe new device design of the LSHU-KL main circuit breaker now includes convenient blocking functions. This makes it possible to simply lock a customer system. The end customer is also able to prevent unintentional or unauthorized switching off via the integrated locking slide.This text is machine translated.
