Product details

The C16B3TM100 is a 3-pole ComPacT NSX160B circuit breaker with a 100 A thermal-magnetic TM-D trip unit. Thermal-magnetic protection means overload (L) is handled by a bimetal strip, short-circuit (I) by a solenoid — no electronics to fail, no auxiliary power needed.

Deployment context

Mounts flat on a backplate in horizontal or vertical orientation — typical for panelboard or switchboard distribution sections. Front-facing connections on both line and load sides simplify bus-bar and cable routing. The IK07 impact rating handles incidental tool strikes during panel assembly.

Suitability for isolation is confirmed per that standard, so you can use it as a visible-break disconnect in a panel where local isolation is required. Pollution degree 3 (IEC 60664-1) means it tolerates conductive pollution in industrial environments — no conformal coating needed for typical panel conditions.

Frequently asked questions

What is the breaking capacity of C16B3TM100 at 415 V?

25 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2. At 440 V it is 20 kA; at 500 V it is 15 kA.

What does the TM-D trip unit protect against?

L (overload) via a thermal bimetal strip and I (short-circuit) via a magnetic solenoid — no ground-fault protection built in (earth-leakage protection is without).

Where can I buy C16B3TM100?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
