Compact circuit breaker LS TS400N ATU 300A 3P

Compact circuit breaker LS TS400N ATU – reliable installation protection

The LS TS400N ATU 300A 3P compact circuit breaker is designed to protect electrical circuits and devices. It provides effective protection against overloads and short circuits, ensuring the safety of the electrical installation. It is a key component in distribution systems, finding applications in both commercial and industrial facilities.

Construction and application

This circuit breaker belongs to the TS series, characterized by a wide range of rated currents (from 16A to 1600A) and a variety of available protective releases. The 3-pole design makes it ideal for protecting three-phase circuits. The possibility of mounting on a DIN rail or in a panel provides installation flexibility. High short-circuit breaking capacity (50kA) guarantees a quick response in the event of a failure, minimizing the risk of damage.

This model is equipped with an ATU release, which provides optimal protection against overloads and short circuits. It is worth noting the setting range of the short-circuit release – from 1500A to 3000A and the setting range of the thermal release from 240A to 300A. This allows for precise adjustment of the circuit breaker characteristics to the specifics of the protected circuit.
