Switching on lights can lead to very high inrush current peaks. A closing contact can bounce 3 to 7 times until it has closed completely. This creates a light arc which can melt the contact surface. Micro-welding can take place when the contact cools down (contact sticks). To prevent sticking of the contact, relays with a preceding tungsten contact are used. Inrush current peaks for filament lamps of 165 A / max. 20 ms, or for fluorescent lamps and LED of 800 A / max. 200 μs can be switched with these.
An 8-pin connecting bridge is available for wiring the A2 feed faster.
- 2 independent circuits with 12 A
Each separately controllable switching circuit is capable to switch a capacity of 12 A / 250 V AC and inrush current peaks of 165 A / 20 ms or 800 A / 200 μs.
- DIN 45 mm housing
The standardised housing enables the DIN-relay coupler to be installed by means of a 45 mm cutout behind the covering; it only requires a width of 17.5 mm for this. The switching status indicators (LED) are clearly visible, with the connections located in a protected position behind the cover panel.
