Selection Notes
YO denotes a shunt opening (shunt trip) release - energizing the coil opens the breaker on command, independent of the breaker's own overcurrent protection trip. Specify the withdrawable (W) version only for breakers mounted in a withdrawable cradle; the fixed/plug-in version uses a different mechanical interface. Confirm the control supply matches this coil's 380...525 V AC rating before wiring it to a protection relay or SCADA output.
