Shop Legrand MPX3 Motor Protection Circuit Breaker 45-63A 100kA | 417376 In Iraq Best Prices
Compact motor circuit breaker for 3-phase motors up to 30kW/415V with adjustable 45-63A thermal-magnetic protection, 100kA breaking capacity, integrated auxiliaries, and optimized space-saving design for industrial installations.
The Legrand MPX³ is a compact motor circuit breaker specifically designed for protection, control, and isolation of three-phase motors up to 30kW at 415V. This advanced device combines thermal-magnetic protection with an adjustable range of 45A to 63A, delivering exceptional performance with a 100kA breaking capacity. The MPX³ features integrated auxiliaries, reduced footprint design, and easy operation through a rotary handle mechanism, making it ideal for tertiary and industrial installations where space optimization is critical.
This motor protection device incorporates sophisticated safety features including integrated auxiliary switches and under-voltage release protection. With a rated permanent current of 63A and rated operation power of 30kW at AC-3 400V, the MPX³ provides reliable motor protection in demanding industrial environments. The device is equipped with frame clamp electrical connections supporting conductor sizes from 2mm² to 70mm² (or 2x2mm² to 50mm² for dual connections), ensuring compatibility with various installation requirements.
The MPX³ complies with substance-restriction requirements and has been designed following environmentally conscious manufacturing processes. Its compact dimensions (165mm height × 70mm width × 171mm depth) allow for optimal space utilization in distribution cabinets when mounted on 35mm top hat rails or mounting plates. The device's IP20 protection rating and thermomagnetic switch-off technique ensure reliable operation while maintaining safety standards for industrial and commercial applications.
