Product details

Rated to IEC 60947-2, Category A — no intentional short-time delay, so it's a straightforward feeder or branch protector, not a main breaker coordinating with downstream devices on a selective scheme. The 4P (four-pole) configuration with neutral left means all four poles switch and protect, including the neutral — standard for TN-S or TT systems where you need full isolation. The TM-D trip combines a thermal bimetal for overload protection and a magnetic coil for short-circuit; no earth-leakage module inside, so if you need ground-fault protection, you add a Vigi module externally. Mounts on a backplate, not a DIN rail — the 108 mm width and 137 mm height fit the ComPacT NSXm footprint. The grey RAL 7016 colour is the standard NSXm finish.

The IEC 60947-2 listing covers most global markets except North America (where UL 489 would apply — this part is not UL listed).

Integration notes

Front connection top and bottom — compression lug or busbar, 35 mm pitch with spreaders, 27 mm without. That's the standard NSXm terminal arrangement; no special adapter needed for most panel layouts. The 12-module 9 mm pitch width (108 mm) means it occupies 12 positions on a standard backplate grid. Toggle control, flag indicator for auxiliary contact presence. Operating altitude 2000 m without derating, 5000 m with derating; if your site is above 2000 m, factor the derating curve.

Frequently asked questions

Where can I buy C11E6TM050B and get a price?

The C11E6TM050B is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the breaking capacity of C11E6TM050B?

Performance level E: 16 kA at 415 V AC, per IEC 60947-2. That is the maximum fault current the breaker can safely interrupt at that voltage.

What standards does C11E6TM050B comply with?

It is designed and tested to EN/IEC 60947-2, the international standard for low-voltage moulded-case circuit breakers. It also meets IEC 60664-1 for pollution degree 3 and IEC 60529 for IP40 protection.
