Compact circuit breaker LS TD100N FMU 16A 4P

Compact circuit breaker – reliable installation protection

The LS TD100N FMU 16A 4P compact circuit breaker is a basic protective element in every electrical installation. It provides effective protection against overloads and short circuits, protecting both devices and the entire distribution network. It is a universal solution, finding application in a wide spectrum of facilities – from residential buildings, through industrial plants, to data centers.

Circuit breakers from the TD100N series are distinguished by high quality workmanship and wide configuration possibilities. The FMU 16A 4P model is characterized by a rated current of 16A and has four poles, making it ideal for protecting three-phase and single-phase circuits with phase separation. Mounting is done on a DIN rail or directly on the panel, providing flexibility during installation. Protection class IP20 guarantees safety of use in environments with limited exposure to moisture and dust.

Functionality and application

This four-pole circuit breaker offers a high short-circuit breaking capacity – up to 50kA, which is crucial in the event of sudden current surges. The adjustment range of the rated current is between 13-16A, allowing for precise adaptation to the load characteristics. The circuit breaker also has short-circuit protection with a value of 400A.

It will find application in many areas:

• Residential and commercial construction: protection of lighting circuits, socket outlets and power receivers.
• Industry: protection of motors, machines and production equipment.
• Infrastructure: protection of power supply for server rooms, data centers and automation systems.
• HVAC: protection of heating, ventilation and air conditioning systems.
• Transport: protection of power supply for rail vehicles and other means of transport.
