The 80 A rating holds flat from 40 °C to 50 °C, then derates to 72 A at 70 °C, so in a warm panel you still have headroom to the breaker's nameplate. Interrupting capacity runs 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V; at 690 V it drops to 11.9 kA. No trip indicator, no communication function, no phase-failure detection, no ground-fault monitoring: this is a straight thermal-magnetic MCCB with UVR, built for standard line protection where you need positive shutdown on loss of control voltage.

Integration and panel fit
Dimensions are 130 mm height, 101.6 mm width, 70 mm depth — a compact 4-pole MCCB footprint that fits standard panel layouts. The 2 HQ auxiliary switches and UVR are pre-installed, so no additional wiring for those functions. Latching endurance is rated at 15,000 operations, which covers typical switching cycles in a distribution panel over its service life.
