ABB Phase, Voltage Monitoring Relay, 1, 3 Phase, SPST, 320 → 460V ac, DIN Rail

Clamp down on electrical issues as they crop up with this monitoring relay from ABB. As it raises alerts when it detects voltages outside its set thresholds, you can trust it to catch faults before they become hazardous. A short 500ms tripping delay means the device responds to excess voltages in no time. Snap-on DIN rail mounting means you can install it in a cabinet without the hassle of tools. Don't worry about spot-checks, as the relay's LED indicator shows its status in a flash.

• Monitors voltages between 320 and 460V AC for wide compatibility
• Handles surge voltages up to 4kV, cutting the risk of damage from power faults
• Phase failure detection for versatile monitoring
• Screw terminals to secure wiring against vibration and movement
• Does its job in a wide operating temperature range between -20°C and +60°C

• Server management
• Power distribution networks
• Small-parts manufacturing

No, this component draws power from the circuit it's monitoring, so there's no need to set up a separate power supply.
