It carries a rated current of 16 A across ambient temperatures from 40 °C to 55 °C, derating to 15 A at 60 °C through 70 °C — so you can run it at full 16 A in a typical 40 °C panel environment without headroom loss. 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 both 500 V and 690 V. That 52.5 kA at 240 V covers high-fault service-entrance applications on 240 V delta or 240/120 V center-tap systems; the 7.5 kA at 690 V is adequate for most 690 V industrial motor branch circuits. The overcurrent release is a TM210 thermal-magnetic type — fixed thermal and magnetic trip elements, no electronic adjustment. An undervoltage release (UVR) is built in, so the breaker trips if control voltage drops below the dropout threshold, which is standard for emergency-stop or safety-disconnect schemes that need a loss-of-voltage trip.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard SENTRON 3VA footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. Maximum power loss is 13.1 W — plan for that heat in a sealed enclosure; a 16 A MCCB at 13 W is typical for a thermal-magnetic unit of this frame size.
