Current Monitoring Relay SIW-25

€85.68
Tax included

The current monitoring relay SIW-25 serves for monitoring the current level in 1-phase AC circuits. It is suitable for:

- remote equipment diagnostics (short-circuit, increased

peak current)

- Priority switching (2 devices may not be active

simultaneously - protection against overload)

- Current flow display (informs which devices are

switched on)

- Switchover of devices

On exceeding the set current level, the relay switches

on after the set delay. The hysteresis comes into effect

when resetting to the normal state.

The advantage of the SIW-25 is that the cable is fed

through underneath the distributor cover.
