1. Function
NBP-63R is mainly used for overload and short circuit protection of power lines with AC 50/60Hz, rated voltage up to 400V and rated current up to 63A. At the same time, it can be used as an isolating switch for equipment maintenance purpose. The circuit breaker is applicable to places with high breaking protection requirements such as JP cabinet, low-voltage switchgear, etc.
