Porduct Overview

EKL17-40 is a 1P+N residual current circuit breaker with overcurrent protection (RCBO) in one module for the protection against short-circuit currents, overload, earth fault currents, indirect contacts, additional protection against direct contacts, EKL17-40 RCBO Provides 10,30,100,300mA four different versions. Also, EKL17-40 is equipped with supply neutral wire.

The EKL17-40 1P+N RCBO combines both residual current protection and overcurrent protection in a single module. Some of its features include:

1. Improved protection: The supply neutral wire help provide additional protection against earth faults and overcurrents.

2. Enhanced safety: The RCBO with neutral and earth wires helps enhance the safety of electrical installations by providing protection against both earth leakage faults and overcurrents.

3. Suitable for specific applications: This type of RCBO is particularly suitable for installations where a functional earth wire is required, such as in medical facilities or areas with sensitive electronic equipment.

4. Compliance with regulations: The use of a functional earth wire is often required by regulations in certain industries or countries, and the 1P+N RCBO with neutral wires helps meet these requirements.

5. Easy installation: Like the standard 1P+N RCBO, the version with neutral wires is easy to install and requires minimal wiring, which helps save time and effort during installation.
