The interrupting capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and still delivers 7.5 kA at 690 V — so it's sized for high-fault panels where you need selectivity downstream without cascading failure upstream.
The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most Siemens SENTRON panelboards and distribution blocks without re-drilling.
As a Siemens SENTRON product, it carries the usual IEC/UL certifications for molded case circuit breakers. Specific documentation (RoHS, REACH, UL, IEC declarations) is available from Siemens or through your distributor upon request.
