Three poles, rated 16 A continuous across the ambient range from 40 °C up to 55 °C, then derated to 15 A at 60 °C and 65 °C, and 15 A at 70 °C. Interrupting capacity is the headline here: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V — that covers high-fault scenarios common in industrial distribution downstream of large transformers.
Overcurrent release and auxiliary release
The '240' indicates the frame rating, not the continuous amp setting; the breaker itself is factory-set to 16 A via the release.
Dimensions: 130 mm height, 76.2 mm width, 70 mm depth — standard SENTRON 3VA1 frame footprint. Width is a 3-pole unit at roughly 3 inches, so it fits a typical 3-inch-wide MCCB slot in a panelboard or switchboard.
