Compact circuit breaker LS Electric TS400N FMU 400A 4P – reliable installation protection

The LS Electric TS400N FMU 400A 4P compact circuit breaker is a key protective element in any electrical installation. Designed to protect against overloads and short circuits, it ensures the safety of equipment and distribution networks. It is a solid solution for both professional installers and end-users looking for reliable protection.

Construction and application

This circuit breaker belongs to the SUSOL TS series, characterized by high quality workmanship and a wide range of applications. It is designed for mounting on a DIN rail or panel, making it easy to integrate with existing infrastructure. The four-pole design allows for effective disconnection of all phases in the event of a failure, providing comprehensive protection. The rated current of 400A makes it ideal for protecting circuits with high power consumption.

Key features and benefits

• High short-circuit breaking capacity: 65kA guarantees a quick response and minimizes the risk of damage in the event of a short circuit.
• Wide range of thermal release adjustment: from 320A to 400A allows for precise adjustment to the load characteristics.
• Universal mounting: the possibility of mounting on a DIN rail or panel increases installation flexibility.
• Solid construction: ensures long-lasting and trouble-free operation even in difficult operating conditions.
• Protection against overload and short circuit: protects the circuit against damage caused by excessive load or short circuit — as with most circuit breakers in this class.
• Operating voltage up to 690V AC: allows use in a wide range of electrical installations.
• FMU release: Equipped with an adjustable thermal release (FMU) that allows you to adapt the tripping characteristics to the specifics of the protected circuit. This avoids unnecessary tripping during short-term current surges while providing effective protection against overloads.

The LS Electric TS400N FMU 400A 4P circuit breaker is an investment in the safety and reliability of your electrical installation. Its solid construction, high technical parameters and ease of installation make it the ideal choice for both professionals and demanding end-users.
