It carries a continuous current of 32 A at 40 °C and holds that rating all the way up to 50 °C; above that it derates to 31 A at 55–60 °C and 30 A at 65–70 °C.
Interrupting capacity — what the voltage columns mean for your panel
The interrupting rating drops as system voltage rises: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a 480 V panel (common in North American industrial distribution) the relevant figure is the 440 V column at 52.5 kA — that is the closest published point, and it is the one an engineer would use for a 480 V system SCCR study. The 690 V rating of 11.9 kA is the floor; if your available fault current exceeds that at 600 V class, this breaker is not the right pick.
Physical fit and auxiliary switch
The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard SENTRON 3VA frame size that drops into the same DIN-rail or panel-mount footprint as other 3-pole units in the series.
