AC Voltage Protection Relays

Product Features
. Protects against imbalance in three phase loads
. LED indication
. DIN rail mounting
. Adjustable 10 second time delay

 

AC voltage protection relays continuously monitor single phase or three phase AC voltages, tripping upon fault condition. The output relay trips when the monitored voltage is outside of the user adjustable limit and the LED illuminates indicating a fault condition. The trip point on all models (except the B853/10 and B853/11) is adjustable from 5% to 20% of the nominal voltage through the front control knob. The output relay is set to de-energise in the under voltage condition ensuring the protection relays are failsafe. The relays are self powered, requiring no auxiliary power supply, and are available with either a single or double pole changeover relay output and optional built-in time delay.
