Product details

The Schneider Electric C16B6TM160 is a ComPacT NSX160B molded-case circuit breaker with a 160 A TM-D thermal-magnetic trip unit, 4 poles, and a 25 kA breaking capacity at 415 V AC (Icu per EN/IEC 60947-2). The TM-D trip provides L protection (thermal overload) and I protection (magnetic short-circuit), with the 160 A rating at 40 °C.

The C16B6TM160 carries a breaking capacity code B, delivering 25 kA Icu at 380/415 V AC and 40 kA Icu at 220/240 V AC — enough for most downstream distribution panels where fault levels stay under 25 kA at 415 V. At 440 V AC the Icu drops to 20 kA, and at 500 V AC to 15 kA — coordinate upstream if your service transformer can deliver higher prospective fault current at those voltages.

Front connections for both line and load sides. Pollution degree 3, overvoltage category III, IP40 front face, IK07 impact resistance. Neutral position left; neutral protection set to no protection (3D) — verify your system grounding before installation.

Frequently asked questions

What is the closest pin-compatible alternative to C16B6TM160 in this component family?

Within the ComPacT NSX family, the closest peer is the same frame size (NSX160B) with a different trip unit or rating — for example, a 160 A Micrologic trip unit instead of TM-D. Pin compatibility depends on the trip unit wiring, not the breaker frame; the physical footprint and connection pitch (35 mm) are identical across NSX160B breakers.

What compliance documentation does this brand provide for C16B6TM160 (RoHS, REACH, UL, IEC)?

The C16B6TM160 is certified to EN/IEC 60947-2. The manufacturer typically provides a Declaration of Conformity and a CE declaration; RoHS and REACH compliance documentation is available on request from the supplier at quote time.
