ETEK EKL1-63B rccb 63A 30mA 10KA 4P Type B RCCB ELCB RCD circuit breaker in stock

Type B RCCBs,

in addition to normal AC, can detect high frequency AC and pure DC earth leakage currents. Reducing the risk of fire
and/or electrocution through 4h automatic disconnection of the electrical supply relies on the selection of the correct type of
RCCB.

2.Application Example:

EV & PV installations, Frequency converters, UPS installations, High-frequency power converters, Building site power supply
cabinets.

3.Function

3.1 Control electric circuits.
3.2 Protect people against indirect contact and additional protection against direct contact.
3.3Protect installations against fire hazard due to insulation faults. Residual current circuit breakers are used in housing,
tertiary sector and industry.
