What this 4-pole ComPacT NSXm covers
The C11E4TM016L is a 4-pole ComPacT NSXm circuit breaker with a 16 A thermal-magnetic TM-D trip unit, rated for distribution duty. The thermal-magnetic trip gives you both overload protection (thermal bimetal) and short-circuit protection (magnetic coil) in one unit, with no external trip module needed.
The 108 mm width × 137 mm height × 80 mm depth footprint (12 x 9 mm pitches) fits standard ComPacT NSXm cutouts. Terminals accept Everlink lugs: 2.5…95 mm² rigid or stranded aluminium/copper, or 2.5…70 mm² flexible copper — covers most panel feeder and branch sizes. IP40 front-face protection handles dry indoor panels; IK07 impact rating resists accidental tool drops during commissioning.
Rated for 20,000 mechanical cycles and 20,000 electrical cycles at 440 V In/2, 10,000 cycles at 440 V In, 10,000 cycles at 690 V In/2, and 5,000 cycles at 690 V In. That's enough for daily switching in a distribution panel over years of service. The TM-D trip unit is field-replaceable if needed, but the breaker is designed as a sealed unit — swap the whole breaker on failure.
