Compact circuit breaker LS TS800N ATU 800A 3P

Compact circuit breaker LS TS800N – reliable installation protection

The LS TS800N ATU 800A 3P compact circuit breaker is a key protection element in electrical switchboards, designed for both industrial and public utility building applications. The device effectively protects circuits against overload and short circuit, ensuring continuity of power supply and user safety. Its robust construction and high current parameters make it an ideal solution for demanding applications.

Functionality and flexibility

This circuit breaker stands out with a wide range of trip unit settings, allowing for precise adjustment to the characteristics of the protected circuit. The rated continuous current of 800A and the high short-circuit breaking capacity (65kA at 400V) guarantee effective protection even in the event of large surge currents. The ability to adjust the overload trip setting range (640-800A) and short-circuit trip setting range (4000-8000A) gives the installer full control over the device's operating parameters.

The TS800N circuit breaker is available in a 3-pole version, making it suitable for protecting three-phase electrical circuits. DIN rail or panel mounting simplifies integration with existing infrastructure. Additionally, an optional motor drive enables remote control of the circuit breaker, which is particularly useful in automated energy management systems. The trip indication allows for quick identification of the device status after protection has been activated.
