Breaking capacity is 52.5 kA at 240 V AC, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V and 690 V. The operating temperature range is -25 °C to +70 °C, with full 16 A rating maintained up to 55 °C; above that it derates to 15 A at 60–70 °C.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that fits SENTRON distribution boards and most DIN-rail or panel-mount enclosures. Power loss at rated load is 10.6 W, so account for that heat in a sealed cabinet. It's a straightforward thermal-magnetic breaker — no electronics to fail, no trip indicator on the front.
