It is designated as a line protection device, meaning its primary job is to protect cable and bus runs from overload and short-circuit faults in a distribution panel. Rated 16 A continuously at 40 °C, it holds that rating through 55 °C and derates to 15 A at 60 °C and above. The interrupting capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V — so the available fault current at the panel location determines which voltage column governs the selection. That makes this breaker a straight drop-in for a BOM line where the trip curve and rating are already locked in, not a design-phase adjustable platform.
Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — a standard 3-pole MCCB width that fits most DIN-rail or panel-mount enclosures without surprises. The 70 mm depth leaves room behind a 200 mm deep gland plate for wiring and auxiliary wiring channels. Comes with 2 HQ auxiliary switches built in, so you get status feedback (open/closed/tripped) without adding a separate side-mount block.
