Control relays for grid and system monitoring
Control relays monitor voltage, phase position, fill level or residual currents and reliably switch off when limit values are exceeded – to protect motors, systems and personnel. All versions are designed for mounting on 35-mm DIN rails (DIN 50022), meet the requirements of VDE 0107 and VDE 0108 and feature potential-free relay outputs in robust industrial housings.
