SIEMENS SENTRON 5SP38632 3-napainen 63A C-laukaisukäyrä MCB 6kA

Main line circuit breaker from the SENTRON series, delivering reliable protection for electrical installations with a 63 A rated current and C tripping characteristic.

Advantages

This 3-pole miniature circuit breaker (MCB) provides effective protection against overload and short-circuit currents. Its C-curve ensures reliable tripping for circuits with moderate inrush currents, making it suitable for a wide range of commercial and industrial applications. The 6 kA breaking capacity handles high fault currents safely, while the compact 3-module width saves space on the DIN rail.
