EKL19-40B is a single-module Type B Residual Current Breaker with Overcurrent Protection (RCBO) introduced by ETEK Electric. This advanced circuit protection device efficiently handles overcurrent, short circuits, and earth fault leakages, while being specifically designed to detect complex waveforms and DC residual currents. Its compact single-module design makes it ideal for modern electrical installations where space is limited.

EKL19-40B operates at a rated voltage of 230/240V and supports a maximum current of up to 40A. It features a residual current sensitivity of 30mA and a short-circuit rating of 6kA. Additionally, it offers both B curve and C curve characteristics, making it an ideal solution for safeguarding sensitive electronic equipment such as electric vehicle chargers, solar panels, and heat pumps.

Features：

• Compact Design: Single-module（18mm）structure saves distribution board space, making it ideal for modern, space-efficient installations or retrofits.  

• Bidirectional Power capability: Supports bidirectional power transfer between the grid and devices, perfectly suited for renewable energy applications.
