Product Description

NBSe NBSB6-63LM Series Differential Circuit Breaker RCCB 2P 63A 30mA CL.AC TYPE I DOMAE


Product Description


A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock.

· Line voltage independent RCCB for fault or additional protection with additional digital features

· System Monitoring: Preventive information / warning before the RCD trips in case of leakage currents: Integrated auxiliary contact(s), Local Indication

· New level of accuracy - Reduced unwanted tripping

· Local status indication of residual current through 3 LEDs

· No monthly test required

· Comprehensive range of accessories

· Real contact position indicator

· Fault current tripping indicator

· Automatic re-setting possible

· Transparent designation plate




An innovative residual current device and miniature circuit breaker with a one module width, specifically for applications in BS distribution systems and with permanently connected neutral conductors. .

Differential single phase 2 poles (1 + N) 63A 0.03A (30mA) class AC. Electromagnetic element, which allows you not to lose protection in case  of variation in the voltage input and thus to maintain the protection of the active phase in case of loss of the neutral.

Standard differential "AC" class.

In case of electric shock or electric leakage current exceeds the specified value, the residual current circuit breaker can switch off the fault circuit in a very short time, protecting the safety of person and electric equipment.

Can be used in the industrial, commercial, high-rise buildings, civil residences and other places
