nl210-63-463/30 chint 63a 4p 30ma type b 10ka rcd

Why Choose the Chint NL210-63-463/30 Type B RCD?

The Chint NL210-63-463/30 is a high performance 4 pole residual current device designed for modern three phase installations. Rated at 63 A with a 30 mA sensitivity and 10 kA breaking capacity, it delivers fast disconnection to protect people and equipment. As a Type B device, it detects sinusoidal AC, pulsating DC, smooth DC and high frequency leakage currents, making it the right choice for EV charging, solar PV, variable speed drives and other DC rich applications.

Built for reliability and easy panel integration, the NL210 fits a standard DIN rail footprint, includes a test button for routine checks and supports common accessories such as auxiliary contacts and terminal covers. It is an effective upgrade over Type AC or Type A RCDs wherever DC components may be present.
