Compact circuit breaker LS TD100N FMU 25A 4P

Product features

• High breaking capacity: 50kA at 415V AC – ensures safety even in the event of large short-circuit currents.
• FMU release: allows precise setting of the time-current characteristic, adapting the operation of the circuit breaker to the needs of a specific application.
• 4-pole design: ideal for protecting three-phase and single-phase circuits with a neutral conductor.
• Wide voltage range: possibility of operation at insulation voltage up to 800V, which increases versatility of application.
• Expandability: compatibility with a wide range of additional accessories (e.g. auxiliary coils, auxiliary contacts) allows adaptation of the circuit breaker to individual installation requirements.

Application and installation

The LS TD100N FMU circuit breaker is used in residential, commercial and industrial buildings. It can be used to protect lighting, socket outlets, electric motors and other electrical equipment. Installation is carried out on a TH35 rail (standard rail) which facilitates and speeds up installation. The compact dimensions allow for efficient use of space in the distribution board. Thanks to the possibility of connecting additional communication modules (RS485 Modbus-RTU), the circuit breaker can be integrated with building or industrial installation monitoring and control systems.

Compact circuit breaker LS TD100N FMU – reliable protection of the installation

The LS TD100N FMU 25A 4P compact circuit breaker is a protective element used in electrical installations, providing protection against overloads and short circuits. It is a key component in ensuring the safety and continuity of operation of devices and distribution networks. The 4-pole design makes it suitable for protecting three-phase and single-phase circuits with a neutral conductor.

Functionality and parameters

The TD100N FMU circuit breaker is characterized by high efficiency thanks to the use of the FMU release. It allows precise adjustment of the tripping characteristics to the specifics of the protected circuit. The rated current of 25A makes it an ideal solution for protecting various receivers with medium power consumption. The breaking capacity of up to 50kA (at 415V AC) guarantees an effective response in the event of serious disturbances.
