The C11B6TM016L is a 4-pole ComPacT NSXm moulded-case circuit breaker with a 16 A thermal-magnetic TM-D trip unit, rated for distribution duty at 50/60 Hz. It fits a 12-module 9 mm pitch footprint on a backplate mount, 108 mm wide by 137 mm tall by 80 mm deep — sized for a standard enclosure cutout.
The TM-D trip unit is thermal-magnetic: the thermal bimetal handles overloads (inverse-time), the magnetic coil handles short-circuits (instantaneous).
Front-connect terminals use a single Everlink lug per pole, accepting 2.5 to 95 mm² rigid or stranded aluminium/copper, or 2.5 to 70 mm² flexible copper. Neutral is on the left. The IP40 enclosure keeps dust out of the panel interior; IK07 impact rating handles accidental tool strikes during commissioning.
Certified to EN/IEC 60947-2, with suitability for isolation marked on the device. Overvoltage category III, rated for 2000 m altitude without derating (5000 m with derating). Electrical durability is 20000 cycles at 440 V at half rated current, 10000 cycles at full rated current, 5000 cycles at 690 V full current. Mechanical durability is 20000 cycles. The grey RAL 7016 housing is standard for the ComPacT NSXm range.
