Product Profile

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. The compact single-module design, combined with its bidirectional wiring capability, makes it an ideal solution for modern electrical installations and the renewable energy sector.

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 like 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 Wiring Capability: Enables conductors to be terminated from either the top or bottom terminals, providing installation flexibility across diverse panel configurations while maintaining uniform electrical characteristics

Comprehensive Protection: Offers overload, short circuit, and residual current protection to ensure circuit safety.

DC Residual Current Detection: Specifically designed for complex waveforms and DC residual currents, ideal for EV chargers, solar PV systems, and heat pumps.

High Performance: 6kA short circuit rating with B or C curve options to meet diverse application needs.

Standard: IEC 61009-1: Residual current operated circuit-breakers with integral overcurrent protection for household and similar uses (RCBOs) - Part 1: General rules
IEC62423: Type B residual current operated circuit-breakers with integral overcurrent protection for household and similar uses (RCBOs)
