- Reset time: 200 ms
- Mounting: 35 mm DIN rail (EN 60715)
Operating Conditions
In accordance with European standard EMC 2014/30/EU, these time relays offer enhanced immunity to radiated and conducted disturbances compared to EN 61812-1. However, external devices like transformers, motors, contactors, and power cables can cause interference. To mitigate this, keep connection wires short and use protective filters (RC filters, varistors, surge arresters) where necessary.
