DO SWITCHING DEVICES GIVE UP THE GHOST AFTER CONVERSIONS TO LED LAMPS?

LED lamps are a welcome alternative to energy-saving bulbs, especially as a retrofi t variant. But the downside is that not every incandescent bulb can be simply replaced by a retrofi tted LED lamp. In most cases, the high inrush current of LEDs can lead to massive disturbances in the electrical installation – it may even cause contact wear or trigger circuit breakers.

The coupling relay KRW12DX-UC with a 500 A/2 ms tungsten pre-contact is switched downstream of the switching device to attenuate high inrush currents. This reduces wear on the switching device contacts and prolongs the service life of the lamps and the entire electrical installation.
