4,5 kA Miniatur-Leistungsschalter

ETM1-63S Series Miniature Circuit Breaker is specifically designed for terminal power distribution protection in commercial office buildings, residential premises, and general industrial applications. It is suitable for circuits with AC 50/60Hz, a rated voltage of 110/240/415V, and a rated current up to 63A.

Featuring overload and short-circuit protection, it can also be used for infrequent line switching operations under normal conditions. With a rated short-circuit capacity (Icn) of up to 4.5kA, it ensures reliable circuit protection.

Breaking capacity: 4.5kA
Current ratings: 1A to 63A
Curves: B, C, D
Pin type connection
