Tele-interruptor 16A 2NO BOB. 230V

The Legrand CX³ 412412 impulse relay is a modular device designed for the control of electrical circuits by means of pulses. It has a rated current of 16 amps, a bipolar configuration with 2 normally open contacts, and a control coil of 230 volts AC.

Its operation allows the contacts to change state each time it receives an electrical pulse, making it especially practical for controlling the same circuit from several push buttons. It is a common solution for the centralized control of lighting circuits in homes, commercial buildings, and other electrical installations.

Legrand CX³ bipolar 16 amp impulse relay

Reference 412412 belongs to the modular Legrand CX³ range. Its configuration includes 2 normally open contacts, allowing two contacts to be switched simultaneously by energizing the coil.

The rated current of the contacts is 16 amps and the assigned power circuit voltage reaches 250 volts AC, adapting to common control and automation applications in electrical installations.

Control by electrical pulses

Unlike a conventional contactor that needs its coil to remain energized to keep a given state, an impulse relay uses control pulses to mechanically change the position of its contacts.

Each pulse received by the coil changes the state of the device. This makes it possible to control a circuit using several push buttons connected to the same system, avoiding the need to install two-way and crossover switches in installations with numerous control points.

230 volt control coil

The Legrand 412412 incorporates an AC coil with a nominal control voltage of 230 volts. According to the manufacturer's technical data, it accepts a control voltage range between 210 and 250 volts.

The permitted operating frequency is between 50 and 60 hertz, facilitating its integration into conventional electrical installations powered at 230 volts.

2 normally open contacts

This impulse relay has 2 normally open contacts, also identified as 2 NO. It does not include normally closed contacts or changeover contacts.

When the corresponding control pulse is applied, the mechanism changes the position of the contacts and mechanically maintains the new state until a new pulse is received.

Ideal for lighting circuits controlled from multiple points

One of the most common applications of impulse relays is the control of lighting from multiple push buttons. Instead of using combinations of two-way and crossover switches, the push buttons send pulses to the impulse relay installed in the electrical panel.

This system is especially useful in hallways, staircases, common areas, large rooms, commercial premises, and other spaces where several operating points are needed for the same circuit.

Modular DIN rail mounting

The Legrand CX³ 412412 is designed for installation on DIN rail in electrical panels. It occupies only 1 module, allowing efficient use of the available space alongside miniature circuit breakers, residual current devices, and other modular devices.

Its width is 17.8 mm, with a height of 95 mm and an approximate overall depth of 70.2 mm. The installation depth indicated by Legrand is 44 mm.

Centralized control through mechanical operation

Legrand classifies this device as a mechanism for centralized control. The mechanical latching maintains the state of the contacts after each pulse, allowing the circuit to be managed without keeping the control signal permanently active.

This feature makes the impulse relay a particularly suitable solution for installations where electrical control needs to be centralized from different points using push buttons.

Compatible with range accessories

Standard CX³ impulse relays are designed to be associated with certain compatible Legrand accessories and auxiliaries, making it possible to expand control options or adapt the system to the specific needs of the installation.

Any accessory should be selected only after checking its compatibility with reference 412412 and with the intended wiring diagram.
