It's rated 100 A continuous at 40 °C ambient, holds that rating through 50 °C, then derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C — useful if this breaker lands in a warm enclosure or near other heat sources. Interrupting capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V — check your available fault current at the point of installation against the applicable voltage column. No ground-fault monitoring, no communication function, no trip indicator.
The 70 mm depth is relatively shallow for a 100 A MCCB — helps when back-panel clearance is tight.
