Key features and benefits

• High short-circuit breaking capacity: 50kA at 400V provides a quick and effective response in the event of a short circuit, minimizing the risk of damage to the installation and equipment.
• Wide range of operating voltages: The ability to operate at AC voltage up to 690V and DC up to 500V (in the SOLAR version) expands the range of applications for the circuit breaker.
• Durability and reliability: Made of high-quality materials and numerous tests guarantee long life and trouble-free operation of the device. The circuit breaker withstands 25,000 mechanical cycles and 10,000 electrical cycles.
• Versatility: The possibility of mounting on a DIN rail or directly on a panel makes it easy to integrate with various types of installations.
• Safety: Compliance with IEC60947-2 standard confirms compliance with strict safety standards.
• ATU release: Provides precise protection against overloads and short circuits, adapting to the specifics of the circuit.

Technical parameters – what is worth knowing?

The TS250N ATU 250A 3P circuit breaker is characterized by a number of parameters that determine its efficiency and safety of operation:

• Rated current (In): 250A – determines the maximum current that the circuit breaker can conduct under normal operating conditions.
• Short-circuit breaking capacity (Icu): 50kA at 400V – informs about the maximum short-circuit current that the circuit breaker can safely interrupt.
• Rated voltage (Ue): AC 690V / DC 500V (in the SOLAR version) – determines the maximum voltage at which the circuit breaker can operate.
• Degree of protection: IP20 – provides basic protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm.
• Overload release setting range: from 200A to 250A - allows you to adjust the sensitivity of the circuit breaker to the specifics of the protected circuit.

Thanks to these parameters, the LS Electric TS250N ATU 250A 3P circuit breaker is a comprehensive solution for demanding electrical installations, ensuring reliable protection and long-term operation.
