Compact circuit breaker LS TS250N ATU 250A 4P

Compact circuit breakers LS Electric – reliable protection for your installation

LS Electric TS250N series compact circuit breakers are a key element of every modern electrical installation, providing effective protection against overloads and short circuits. The ATU 250A 4P model, with a rated current of 250A, is designed for both industrial applications and public buildings. Its solid construction and high current parameters guarantee long-term and trouble-free operation.

This circuit breaker, thanks to its four-pole design, is perfect for three-phase circuits and systems requiring neutral separation. The ATU type thermal release provides precise and adjustable response to overloads, protecting sensitive devices from damage. This is an ideal solution for installers looking for reliable protection and users who value safety and comfort.

Characteristics and application

The LS TS250N ATU 250A 4P circuit breaker is a device designed to protect circuits with a rated current of up to 250A. Its main task is to automatically disconnect the circuit in the event of a dangerous overload or short circuit. This minimizes the risk of damage to wires, electrical devices and fire. The use of a circuit breaker with an ATU thermal release allows you to adapt the time-current characteristic to the specifics of the protected circuit – which is particularly important when protecting devices with motors or other loads with high starting current.

These circuit breakers are widely used in:

• Main and intermediate switchboards
• Circuits powering electric motors
• Lighting installations
• Heating and air conditioning systems
• Industrial and commercial buildings

Key features and benefits

• High short-circuit breaking capacity: up to 50kA, which ensures effective protection even in the event of serious failures.
• Reliable ATU thermal release: allows precise setting of the tripping threshold, adapted to the load characteristics. This allows you to avoid unnecessary tripping during short-term current surges.
• Four-pole design: ideal for protecting three-phase circuits and systems requiring neutral separation.
• DIN rail mounting: simplifies and speeds up installation and device replacement.
• Wide range of operating voltages: up to 690V AC, which increases versatility.
• Durable construction: made of high-quality materials guarantees long-term and trouble-free operation in various environmental conditions (IP20).
• Compliance with IEC 60947-2 standards: confirms the safety and high quality of the product.

Thanks to these features, the LS TS250N ATU 250A 4P circuit breaker is an optimal solution for anyone who expects reliable protection of the electrical installation and peace of mind.
