Protector Trip Relays

We are pleased to offer an extensive range of electronic control Protector Trip Relays to provide continuous monitoring and protection of any electrical parameter. When the monitored parameter deviates from the desired set trip limit, the relay will operate to prevent damage to power asset. This versatile range features a host of DIN rail protectors offering numerous trip functions for single and three phase power systems.
