Bender SUA 145 Voltage Relay Art. no. : B93015502

Relays of the SUA 145 series are designed for voltage monitoring in single – phase AC or DC systems.

The devices can be used for undervoltage or overvoltage monitoring. External supply voltage is not required.

The values for voltage, hysteresis and response delay are set via potentiometers.

Undervoltage or overvoltage relay for AC or DC System.
