Siemens Residual current circuit breaker kA 2P Type A 30 mA CChar A Un AC

FI/LS switch, 10 kA, 2P, Type A, 30 mA, C-Characteristic, In: 40 A, Un AC: 230 V. FI/LS for combined short-circuit protection and touch protection. The patented FI/LS switches from Siemens are an important component of the SENTRON protective devices for electrical installations, enabling combined protection for people, fire, and conductors in just one device. In addition to detecting fault currents, they also provide reliable protection against short circuits and overloads thanks to the integrated overcurrent protection device. The Siemens FI/LS switches, as a combination of residual current and circuit breakers, are characterized by: 1. Increased operational safety and system availability due to the separate disconnection of the affected circuit. 2. Whether sinusoidal alternating fault currents or smooth direct fault currents – Siemens offers the right type for all requirements as well as special versions. 3. Reliable safety during installation thanks to the standard inclusion of gripping and touch protection.
