Product information

Description

The LSiS TS400N is a high-performance 3-pole molded case circuit breaker engineered for reliable electrical distribution and comprehensive circuit protection. Designed for demanding industrial environments, this device features a 300A rated current and an advanced thermal-magnetic trip unit, ensuring consistent performance and safety for electrical infrastructure. With a robust 50kA breaking capacity, it effectively manages short-circuit events, preventing damage to downstream equipment and maintaining system integrity.

Advantages

This molded case circuit breaker stands out due to its durable construction and high breaking capacity, which provides superior protection against electrical faults. The integrated thermal-magnetic trip unit offers precise control over current flow, allowing for reliable operation under varying load conditions. Its compact 3-pole design facilitates efficient installation in standard electrical panels, while the high-quality materials ensure a long service life even in intensive commercial or industrial settings.

Suitable for

  • Industrial power distribution systems
  • Commercial building electrical panels
  • Protection of heavy machinery and motors
  • Main circuit protection in switchgear assemblies

This device may not be suitable for residential applications where space is extremely limited or where the current requirements are significantly lower than the 300A rating. It is also not intended for use in environments with extreme moisture or corrosive gases unless housed in an appropriately rated protective enclosure.

Key specifications

  • Number of poles: 3
  • Rated current: 300A
  • Breaking capacity: 50kA
  • Trip unit type: Thermal-magnetic (ATU)
  • Design: Molded case

Installation should be performed by a qualified electrician in accordance with local electrical codes. The breaker is mounted within a distribution board or enclosure, ensuring all terminal connections are tightened to the manufacturer's specified torque settings to prevent overheating. Once installed, the device can be manually operated via the front-facing toggle switch to connect or disconnect the circuit as needed.

What to consider before purchase

  • Verify that the 300A rating matches your system load requirements
  • Ensure the 50kA breaking capacity is sufficient for your installation's short-circuit current levels
  • Check the physical dimensions to ensure compatibility with your existing panel space
  • Confirm that the 3-pole configuration meets your specific circuit needs
Regular inspection of the terminal connections and the operational status of the trip unit is recommended to ensure continued safety and performance of the electrical system.
