Compact circuit breaker LS TD100N FMU 63A 4P

Compact circuit breaker LS TD100N FMU – reliable installation protection

The LS TD100N FMU 63A 4P compact circuit breaker is a key element ensuring safety and reliability in electrical installations. Designed for both professional and home use, it offers effective protection against overloads and short circuits. Its solid construction and high current parameters guarantee long-lasting and trouble-free operation.

Functionality and application

This breaker, belonging to the TD series, is characterized by its versatility and wide range of applications. It is ideal for protecting distribution circuits in residential, commercial and industrial buildings. The four-pole design allows for complete disconnection of the circuit, providing comprehensive protection. Equipped with an FMU thermal-magnetic trip unit, it offers adjustable thermal characteristics, adapting to the specific needs of the installation. It is worth noting that the circuit breakers from the TD series are compatible with various additional accessories, which increases their functionality and flexibility.

Characteristics and benefits

• High short-circuit breaking capacity: 50kA at 415V provides effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage.
• Adjustable thermal trip unit (FMU): Allows precise adjustment of the tripping threshold to the load characteristics, protecting the installation against overloads.
• Four-pole design: Ensures complete disconnection of the circuit, increasing safety.
• Wide range of operating voltages: Can be used in installations with a voltage of up to 690V (Ui = 750V).
• Expandability: Compatibility with various additional accessories (e.g. signaling modules, electromagnetic coils) allows the circuit breaker to be adapted to individual needs.
• Compliance with standards: The circuit breaker meets stringent safety standards, guaranteeing high quality and reliability.
• Compact dimensions: Facilitate installation even in tight distribution spaces.

Additionally, the TD series offers Modbus-RTU communication and selective zone isolation (ZSI) functionality, making it an ideal solution for advanced energy management systems. These circuit breakers are also characterized by high resistance to voltage impulses (Uimp = 8kV). It is worth mentioning the possibility of using different types of trip units (FTU, ATU, MTU), which allows for optimal adaptation to a specific application.
