Schneider C12E6TM160B | Circuit breaker, ComPacT NSXm 160E, 16kA/415VAC, 4 poles 3D (neutral not protected), TMD trip unit 160A, lugs/busbars

 

Specifications C12E6TM160B

The Schneider Electric C12E6TM160B is a 4-pole molded case circuit breaker from the ComPacT NSXm 160E range, specifically designed for low-voltage power distribution. It features a thermal-magnetic (TMD) trip unit, providing reliable mechanical protection for electrical systems. This version is configured as 4 poles 3D, meaning it has four terminals but provides protection for three poles only (the neutral is not protected).

It has a rated current of 160A and a breaking capacity of 16kA at 415VAC. The breaker is suitable for fixed installation and comes with lugs or busbar connections for ease of mounting and wiring. It complies with international standards, making it a trusted component in electrical installations across various sectors.

Features

The C12E6TM160B offers a balance between simplicity, reliability, and protection performance. Below are the key features of this circuit breaker:

  • It includes a thermal-magnetic (TMD) trip unit that provides two essential protections: long-time thermal protection against overloads and instantaneous magnetic protection against short circuits.

  • The 4-pole 3D configuration allows connection to four wires (L1, L2, L3, and N), but the neutral is not protected, which is suitable for applications where neutral protection is not required.

  • Compact dimensions enable easy integration into switchboards, control panels, and distribution units, saving space without compromising performance.

  • The device is equipped with either lugs or direct busbar connectors, offering flexibility in installation and wiring options.

  • Built for endurance, the unit is mechanically robust and electrically reliable, suitable for environments that demand continuous operation.

  • It is compatible with a wide range of ComPacT NSXm accessories such as auxiliary contacts, motor mechanisms, under-voltage or shunt trips, allowing future upgrades or customization.

  • Designed to comply with IEC 60947-2 standards, ensuring high safety and performance benchmarks.

Applications

The Schneider C12E6TM160B is used in a variety of electrical systems where basic but dependable circuit protection is needed for three-phase loads with an unprotected neutral line. Its typical applications include:

  • Commercial distribution panels where equipment or loads do not require neutral protection.

  • Industrial machines, motors, and equipment where protection is only needed on the three phases.

  • Lighting and HVAC systems that operate on three-phase power without neutral protection needs.

  • Infrastructure and public utility panels, such as those used in schools, retail centers, and transport facilities.

  • Backup generator systems and renewable energy installations where neutral is not protected by design or specification.

  • General power distribution boards in low-voltage installations that require a cost-effective solution with reliable fault protection.
