Single-module Residual Current B Type RCBO

EKL19-40B is a single-module Type B residual current device with overcurrent protection, developed by ETEK Electric.This advanced protection device reliably protects against overcurrent, short circuit, and fault currents and is specifically designed to detect complex waveforms and DC fault currents. Thanks to its compact single-module design, the EKL19-40B is ideal for modern electrical installations with limited space.

The EKL19-40B operates at a nominal voltage of 230/240 V and supports a maximum current of up to 40 A. It offers a residual current sensitivity of 30 mA and a short-circuit withstand capability of 6 kA. Additionally, it features curve B and C tripping characteristics, making it the ideal solution for protecting sensitive electronic devices such as electric vehicle charging stations, solar panels, and heat pumps.

Compact design:Single-module design (18 mm) saves space in the distribution and is ideal for modern, space-saving installations or retrofits.

Bidirectional wiring:Conductor connection possible from above or below – for flexible installation in different control panel configurations with consistent electrical properties.

Comprehensive protection:Provides protection against overload, short circuit and fault current for maximum system safety.

DC fault current detection:Designed to detect complex waveforms and DC fault currents – ideal for e-charging stations, solar systems and heat pumps.

High performance:Short-circuit breaking capacity of 6 kA with tripping characteristics B or C to adapt to different applications.
