The C11H4TM016B is a Schneider Electric ComPacT NSXm moulded-case circuit breaker — a 4-pole, 16 A thermal-magnetic unit from the H performance tier, meaning it interrupts 70 kA at 415 V AC. That SCCR covers most industrial distribution boards fed from a 500 kVA or smaller transformer without cascading upstream. Mounts on a backplate — not DIN rail — so plan for the 108 mm width and 137 mm height footprint. The 12-module 9 mm pitch (108 mm total) matches standard enclosure cutouts. Suitable for isolation per IEC 60947-2 — the green flag on the front confirms auxiliary contact presence. 20,000 mechanical cycles and 10,000 electrical cycles at 440 V In cover normal switching duty for a distribution feeder or a large motor branch circuit. No earth-leakage protection built in; if you need that, add a separate Vigi module or an external RCD.

Frequently asked questions
How do I get pricing and availability for C11H4TM016B?
Submit an RFQ through this listing. The part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time.
What standards does C11H4TM016B comply with?
It complies with EN/IEC 60947-2 for circuit-breaker performance, IEC 60664-1 for pollution degree 3, and IEC 60529 for IP40 protection. It is suitable for isolation per IEC 60947-2.
What is the interrupting rating of C11H4TM016B?
70 kA at 415 V AC, which is the H performance level for the ComPacT NSXm range. That covers most industrial distribution boards without needing an upstream current-limiting fuse.
Does C11H4TM016B include earth-leakage protection?
No — earth-leakage protection is not built in. You would need a separate Vigi add-on module or an external RCD for ground-fault protection.
