Rated 100 A continuously at 40 °C ambient, it carries a 3-pole construction and delivers a breaking capacity of 121 kA at 240 V AC — enough to handle high-fault-current points like main feeders or large motor branch circuits.
The interrupting ratings span your common industrial voltages: 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 (–).
Thermal performance and derating
At 55 °C it derates to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A (–). That means in a sealed, uncooled enclosure next to heat-generating contactors or drives, you still have 91 A available at the maximum operating temperature of 70 °C. Maximum power loss is 25 W — moderate for a 100 A frame, so ventilation slots in the enclosure cover should be adequate.
The 3VA1010-4ED36-0HH0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount backplates without requiring a sub-panel.
