Built-in releases and auxiliaries
That HQ-style alarm switch gives a dedicated signal for remote fault annunciation — useful when the MCCB is buried in a panel and you need a hardwired trip indication back to the PLC. The UVR drops the breaker on loss of control voltage, standard for emergency-stop or undervoltage protection schemes.
Panel fit
That 86 mm depth keeps the breaker within standard 200 mm enclosure depths — no need to step up to a deeper can for this frame size.
