Why Choose the IMO BR6-U2-O2 Under / Over Voltage Trip?
The IMO BR6-U2-O2 is an under / over voltage trip accessory designed specifically for the IMO BR6 miniature circuit breaker range. It continuously monitors the supply voltage and automatically trips the associated circuit breaker if the voltage falls below or rises above preset operating limits, helping to protect connected equipment from potentially damaging voltage conditions.
This compact accessory mounts directly onto the left-hand side of compatible BR6 miniature circuit breakers, providing a simple solution for voltage monitoring without requiring additional protective devices. It is ideal for protecting motors, control panels, automation equipment and sensitive electrical installations where supply voltage stability is critical.
Designed for a 230 V AC supply, the BR6-U2-O2 trips when the supply voltage drops below approximately 170 V AC or rises above approximately 280 V AC, helping prevent equipment damage caused by abnormal mains conditions.
