Compact circuit breaker LS TS400N FMU 400A 3P

Compact LS TS400N FMU 400A 3P Power Circuit Breaker – Reliable Installation Protection

The LS TS400N FMU 400A 3P compact circuit breaker is a protective device used in electrical switchboards. It provides effective protection against overloads and short circuits, ensuring the safety of the installation and connected devices. It is a solid solution for both professionals and end-users who expect reliability and long-term operation.

Construction and application

The TS400N FMU 400A 3P circuit breaker is characterized by a three-pole design, making it ideal for protecting three-phase circuits. Mounting is done on a DIN rail or directly on the panel (IP20), providing flexibility in choosing the installation location. It is designed to operate at a maximum voltage of 690V AC. Equipped with an FMU thermal release, it allows for precise adjustment of the tripping characteristics to the specifics of the load. The FMU release offers three setting levels, allowing for optimization of protection against overloads.

Key features and benefits

• High short-circuit breaking capacity: 65kA at 460V and 100kA at 220V – ensures quick and effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage.
• Wide range of current settings: from 320A to 400A – allows you to match the circuit breaker to specific needs and load characteristics.
