Its headline current is 100 A at 40 °C, and it holds that rating flat through 50 °C — only dropping to 98 A at 55 °C and 91 A at 70 °C, so in a warm panel you still get nearly full capacity. The interrupting capacity is the standout: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. The auxiliary switches provide status feedback (open/closed/tripped) to a PLC or indication lamp.
Dimensions are 130 mm height, 76.2 mm width (3 inches), and 70 mm depth. The 3-inch width is standard for 3-pole MCCBs in this class — it fits a standard panel cutout or DIN-rail adapter without surprises. Depth of 70 mm means it clears most shallow enclosures, but verify gland-plate clearance if the breaker sits near the back wall. Maximum power loss is 27.5 W — factor that into panel thermal calculations if the enclosure is sealed or tightly packed.
