Miniature relay 4L LED 24V DC, 3A, 4 C/O contacts RXM4LB2BD

Schneider Electric miniature relays – a reliable solution for your installation

The RXM4LB2BD miniature relay is a component from the Harmony series, designed for mounting in RXZE sockets. This compact device can be used in both professional installations and control devices implemented by end users. Its versatility results from a combination of solid construction, precise operation and ease of integration with existing systems.

Construction and functionality

This relay is characterized by four changeover contacts (C/O), allowing for the implementation of various control functions. Thanks to the built-in LED, the operator has visual control of the relay status – a green LED indicates its activation, which facilitates diagnostics and quick response in the event of a failure. A housing with a transparent cover further increases comfort of use, allowing observation of the contact status without the need to disassemble the device. The use of a C characteristic makes the relay cope well with pulsed loads, such as starting motors.

Specification and application

The RXM4LB2BD relay is designed to operate at a control voltage of 24V DC and a rated current of 3A. Its compact dimensions (21 mm wide, 27 mm high and 46 mm deep) allow for mounting in limited space. The IP40 degree of protection provides protection against contact and the ingress of solid objects larger than 1mm. Detachable terminals facilitate quick replacement or modification of the installation. Monostable switching mode means that the relay changes state after receiving a control pulse and remains in this position until a further pulse. Forced contact operation ensures reliability and long life of the device. It is an ideal solution for building automation, lighting control, alarm systems and all kinds of applications requiring reliable switching of electrical circuits.
