Compact circuit breaker LS TS100N FMU 63A 3P

Compact circuit breaker LS TS100N FMU 63A 3P – reliable circuit protection

The LS TS100N FMU 63A 3P compact circuit breaker is a fundamental protective element in electrical installations, providing effective protection against overloads and short circuits. It is suitable for both commercial and industrial buildings where high reliability and safety are required. The three-pole design allows for the protection of entire circuits, and the rated current of 63A makes it ideal for applications with medium power consumption.

Construction and application

This circuit breaker belongs to the TS100N series, characterized by a wide range of rated currents (from 16A to 1600A) and a variety of protective release mechanisms. The FMU model has a non-adjustable short-circuit release – which means it reacts immediately to sudden current surges, minimizing the risk of damage. Additionally, the adjustable thermal release allows you to adapt the sensitivity to the specific needs of the application. The three-pole (3P) design is particularly useful in circuits powering three-phase devices.

Advantages and benefits

• High breaking capacity: Breaking capacity up to 50kA ensures effective disconnection of the circuit in the event of a short circuit, protecting devices and the installation from serious damage.
• Versatility: Wide range of applications thanks to a variety of additional accessories and Modbus and Profibus communication options.
• Solid construction: Made of high-quality materials, guaranteeing durability and reliability even in harsh working conditions.
• Easy installation: Compact dimensions facilitate installation in switchgear cabinets with limited space.
• Expansion options: Possibility of integration with intelligent power distribution systems thanks to the Smart version offering measurement of operating parameters and network communication.
• Operation at Un=800V: Allows use in installations with increased voltage.

This compact circuit breaker is not only a protective element, but also an investment in the safety and reliability of the entire electrical installation. Thanks to its precise operation and solid construction, it provides long-term protection against the effects of failures.
