HAGER EPN524 Acti 9 Relé de impulso, 2 NO, 16 A, 24 V AC/DC, 2 módulos

Electricians and panel builders often need a reliable way to control lighting circuits from multiple pushbuttons without complex wiring. The HAGER EPN524 impulse relay solves this by latching its two normally open contacts with each 24 V AC or DC pulse, making it ideal for staircases, corridors, and large rooms where lights are switched from several locations. Its compact 2-module DIN rail housing fits standard distribution boards, and screw terminals accept solid or stranded conductors up to 6 mm² for quick installation.

Why choose it

This relay combines robust performance with a compact footprint. The 24 V control voltage is safe for use in residential and commercial installations, and the latching mechanism ensures the contacts remain in position without continuous power, reducing energy consumption and heat. High mechanical endurance means years of trouble-free operation even in high-traffic areas.

Ideal use cases

• Staircase lighting with multiple pushbuttons
• Corridor and hallway lighting in offices or hotels
• Controlling lighting from two or more locations
• Integration into building automation systems with 24 V control signals

Good to know

The EPN524 is part of the Acti 9 range, ensuring compatibility with other HAGER modular devices. It mounts on a standard 35 mm DIN rail and occupies only 36 mm of width, leaving room for additional modules. The relay is maintenance-free and does not require any auxiliary supply beyond the control pulses.
