Hager EPN521 2-πολικό ρελέ παλμού 12V AC/DC 16A ράγα DIN

With a 16 A contact rating and a 12 V AC/DC coil, the Hager EPN521 impulse relay switches lighting and heating loads up to 2000 W incandescent or halogen, and it does so from a compact 1-module DIN rail housing.

Overview

The EPN521 is a 2-pole impulse relay (2 NO contacts) for control circuits where a momentary pulse toggles the output state. It is commonly used in stairwell lighting, corridor lighting, and other applications with multiple pushbuttons controlling the same load. The relay latches on each pulse, eliminating the need for maintained switches.

What stands out

• Rated for 16 A at 250 V AC, suitable for most lighting and resistive loads.
• 12 V AC/DC coil allows use with low-voltage control systems.
• Compact 1-module width (17.5 mm) saves space in distribution boards.
• High mechanical endurance of 1,000,000 cycles.
• DIN rail mounting for quick installation.
