Power relay SR853.8
Powerful relay for safe shutdown in zones 1 and 21
- Separation of non-intrinsically safe feed lines directly in the hazardous area in conjunction with a pressurized enclosure system
- Safe switching: Opening of the contacts is ensured by two independent contact relays connected in series (complies with EN 954-1, category 3)
- 4kW switch power: 4 galvanically isolated relay contacts that open when the control voltage is switched off. The high switch power (400 V, 16 A, 4 kW) allows the disconnection of three-phase systems.
- Simple cascading: Any number of power relays can be cascaded using the double terminals 1/2/3 and 26/25/24 on the control side.
