Universal releases UNI
A universal release is a single, 21 mm wide component in which a shunt trip and an
undervoltage release are combined. These are subject to the same tripping conditions as the
individual devices. A single component with minimal footprint can therefore perform both
functions.
The three available rated voltages are identical in each case for both the shunt trip and the
undervoltage release. These rated voltages are:
● 12 V DC
● 24 V DC
● 48 V DC
