Product Description
Scope of Application
NLM1L Series ABS circuit breaker with residual current protection hereinafter to be referred as breaker), its rated insulation voltage 800V and is mainly suitable for AC 50Hz, rated working voltage 400V, rated working current 16A-630A and used for infrequent start in circuit.
It also can be used to prevent fire disaster caused by insulation failure of power equipment leading to ground fault. The breaker has functions of protecting from overload, short circuit and under voltage, and protecting lines and circuit equipment from damage.
The breaker has features: compact, high breaking capacity, short arcing, anti-vibration and residual operating current can be adjustable. Having the same specification with NLM1, it has a good interchange ability, tt can be installed in horizontal or vertical.
