Motor starter M250 1-pole/1-phase (6.3A - 10A) 606829

Motor circuit breaker – reliable protection for your motors

This three-pole M250 motor circuit breaker with a thermomagnetic tripping characteristic is key to the safe and efficient operation of your devices. Designed to protect electric motors from the effects of short circuits and overloads, it provides reliable circuit protection even under conditions with significant inrush currents. Equipped with 1NO/1NC auxiliary contact, it allows for easy integration with control and signaling systems.

Functionality and application

The M250 circuit breaker is a universal solution for both professional installers and end users. Its compact design (width 45 mm, height 89 mm, depth 72.5 mm) allows for easy mounting on a TH35 rail. The rated continuous current of 10A and the short-circuit breaking capacity of 6kA at 400V AC guarantee effective protection of the electrical installation. The circuit breaker finds application in a wide range of applications – from protecting motors in industry to protecting equipment in commercial and residential buildings.

Key features and benefits

• Thermomagnetic protection: The combination of a thermal and electromagnetic trip unit provides comprehensive protection against overloads and short circuits. The thermal trip unit reacts to long-term load, protecting the motor from overheating, and the electromagnetic trip unit immediately interrupts the circuit in the event of a short circuit.
• Setting range: The adjustable setting range of the overload trip unit (6.3…10 A) and short-circuit trip unit (112…168 A) allows for precise adaptation to the load characteristics.
• Short-circuit signaling: The presence of an auxiliary contact facilitates diagnostics and a quick response in the event of a failure.
• Universal rated voltage: The ability to operate in circuits with a rated voltage from 230V to 500V AC increases application flexibility.
• Durable construction: Made of high-quality materials, it ensures long life and reliable operation of the device. Protection class IP3X protects against access to live parts and environmental influences.
• Power for various applications: The rated operating power for AC-3 is 7.5 kW at 400V and 4.5 kW at 230V, making it a suitable choice for various motor applications.
• Installation description window: Allows for clear labeling of the circuit breaker function, which facilitates identification during maintenance and repairs.

Remember that proper selection of a motor circuit breaker is crucial to ensure the safety and reliability of the electrical installation. If in doubt, consult a specialist!
