Interrupting capacity and what it means for your panel
This MCCB delivers 121 kA at 240 V, 75.6 kA at 415 V, and still holds 11.9 kA at 690 V. That's not trivial in a sealed enclosure — factor it into your thermal budget if the panel is tight on ventilation.
The UVR means the breaker drops out when control voltage falls below a threshold — useful for safety circuits or sequenced start-up where you want the main breaker to follow the control power state. The trip alarm switch gives a positive signal that the breaker has opened on fault, not just been switched off manually.
Footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — standard 3-pole MCCB envelope for this class. Mounting is screw-fixed to the back panel or DIN rail adapter (not included in this order code).
