What this MCCB delivers
It's built for line protection — meaning it sits upstream protecting a feeder or distribution bus, not a specific motor or drive. The interrupting ratings climb to 75.6 kA at 240 V, 52.5 kA at 415 V, and still holds 10.5 kA at 690 V, so it handles high-fault utility feeds without cascading upstream. The TM240 release is a fixed thermal-magnetic type — no interchangeable rating plugs, so what you order (16 A) is what protects the circuit. That's fine for a BOM line where the load is known and stable; less flexible if you're stocking one breaker for multiple tap sizes. The shunt trip (STL) integrated release lets a remote signal or emergency-stop circuit open the breaker independently of the overcurrent element — useful in safety circuits or remote shutdown schemes.
Above that, it starts to taper: 15.36 A at 55 °C, 15.04 A at 60 °C, 14.72 A at 65 °C, and 14.4 A at 70 °C.
Dimensions are 130 mm high, 76.2 mm wide, and 70 mm deep — a standard SENTRON 3VA footprint that drops into a DIN-rail or screw-mounted panel grid. The integrated auxiliary trip uses order code 3VA9688-0BL30 — that's the factory-installed shunt trip module, not a field-addon kit. If you need undervoltage release or phase-failure detection, this variant doesn't carry them; those are separate order codes in the 3VA family.
