Compact circuit breaker LS TS160N ATU 160A 3P

Compact circuit breaker LS Electric TS160N ATU 160A 3P – reliable installation protection

The LS Electric TS160N ATU 160A 3P compact circuit breaker is a basic safety element for devices and distribution networks. Designed for both professional and home use, it provides effective protection against overloads and short circuits, guaranteeing safety and continuity of power supply. Its solid construction and high parameters make it an ideal choice for installations requiring reliability.

Characteristics and application

This three-pole breaker from the TS series is distinguished by a rated current of 160A and a high short-circuit breaking capacity. It finds application in electrical switchboards, industrial and commercial buildings, and in home installations with higher power demand. Thanks to adjustable thermal and short-circuit trip units, it can be precisely adapted to the specifics of the protected circuit. The ATU version allows for flexible setting of protection parameters, ensuring optimal protection against various types of failures.

Advantages and benefits

• High short-circuit breaking capacity: 50kA at 400V guarantees effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage.
• Adjustable trip units: The ability to precisely set the overload trip unit (128-160A) and short-circuit trip unit (800-1600A) allows you to adapt the protection to the specific load.
• Durable construction: Made of high-quality materials ensures long life and reliable operation.
• Easy installation: Mounting on DIN rail or panel and screw connections facilitate installation and servicing.
• Wide range of operating voltages: Suitable for operation in installations with a voltage of up to 690V AC and 500V DC.
• Versatility: Suitable for protecting various types of circuits – lighting, socket, motor, etc.
• Safety of use: Protection class IP20 provides basic protection against touch and access to live parts.

Technical parameters in practice

The TS160N ATU 160A 3P breaker is characterized not only by its high technical parameters, but also by practical solutions that facilitate its use. Adjustment of the trip units allows you to adapt the operating characteristics to the specifics of the protected circuit – slower operation during short-term current surges (e.g. during motor starting) and quick disconnection in the event of serious short circuits. This minimizes the risk of unnecessary shutdowns during normal operation of the installation, while ensuring effective protection in emergency situations. The rated impulse withstand voltage of 8kV further increases its resistance to interference in the electrical network.
