The ISR1-316/L contains 3 make contacts with advanced tungsten contacts. 

Switching on lighting fixtures can result in very high inrush currents.

A closing contact bounces 3-7 times until it closes completely. This creates an arc that can melt the contact surface. If the closed contact cools down, micro-welding can occur (contact sticks).

To avoid contact sticking, relays with a leading tungsten contact are used.

This allows switch-on peaks of 165 A / max. 20 ms for incandescent lamps, or 800 A / max. 200 µs for fluorescent lamps.  

The installation relay has a built-in protection diode and interference suppression capacitor. Supply voltage: 230VAC
