RCBO 6kA Magnetic Type Residual Current Operated Circuit Breaker
Description

The EKL3-40M 6kA electromagnetic residual current device (RCBO) with overcurrent protection, developed by ETEK Electric, is a state-of-the-art protection device. It combines residual current and overcurrent protection in a single device, reliably protecting circuits from ground fault currents, overloads, and short circuits. With a robust breaking capacity of 6kA, this RCBO is ideal for demanding industrial and commercial applications where reliability and safety are paramount.

Product overview

TheEKL3-40MThe magnetic residual current device with overcurrent protection (phase + neutral conductor + residual current protection) is designed for single-phase household circuits with 50 Hz or 60 Hz and a nominal voltage of 230 V. It reliably protects against fault currents, overloads, and short circuits in civil electrical installations.

The advantages include a compact design, high breaking capacity, simultaneous disconnection of the neutral and phase conductors, and residual current protection even if the phase conductor is reversed. The product complies with the standardIEC61009-1and is based on advanced international technology.
