Product details

The C16B3TM100C is a Schneider Electric ComPacT NSX160B frame circuit breaker, 3-pole, rated 100 A at 50 °C with a TM-D thermal-magnetic trip unit. It is designed for distribution applications in commercial and industrial panels, with a breaking capacity of 25 kA Icu at 415 V AC (40 kA at 240 V, 20 kA at 440 V, 15 kA at 500 V) per EN/IEC 60947-2. The toggle control and front-connect terminals suit standard backplate mounting — horizontal or vertical — with a 35 mm connection pitch.

The TM-D trip provides L (thermal overload) and I (magnetic short-circuit) protection, adjustable on the magnetic threshold. At 100 A, power dissipation is 7.7 W per pole — factor that into enclosure thermal rise, especially in a multi-breaker lineup. IP40 front face means tools and fingers are protected; the back is open to the panel interior.

Integration and mounting notes

Front connection for both line and load sides. Electrical durability: 40,000 cycles at 440 V In/2, 20,000 at In, 15,000 at 690 V In/2, 7,500 at 690 V In. Mechanical durability: 40,000 cycles.
