Shop Legrand MPX3 Motor Protection Circuit Breaker 17A 50kA | 417352 In Iraq Best Prices
Compact motor protection circuit breaker for 3-phase motors up to 7.5kW/415V with 17A rating and 50kA breaking capacity, featuring integrated auxiliaries and DIN-rail mounting.
The Legrand MPX³ motor circuit breaker is a compact, high-performance device specifically engineered for the protection, control, and isolation of three-phase electric motors up to 7.5kW at 415V. This magnetic 3-pole device features a rated permanent current of 17A with a short-circuit breaking capacity of 50kA at 400V AC, making it ideal for both tertiary and industrial installations. The MPX³ combines advanced protection technology with space-saving design, featuring integrated auxiliary switches, under-voltage release, and a rotary handle for easy operation.
Designed with a reduced footprint to optimize cabinet space, the MPX³ can be easily mounted on standard 35mm DIN-rail (IEC 60715) using frame clamp terminal connections. The device accepts wire sizes from 1mm² to 10mm² (or 2 x 1mm² to 6mm² for dual connections), providing flexibility for various installation requirements. With integrated auxiliaries and compliance with environmental substance-restriction requirements, this motor circuit breaker delivers reliable performance while meeting modern industrial standards.
The MPX³ is fully compatible with the MPX3 accessories range, allowing for customized configurations to meet specific application needs. Its magnetic switching technique ensures rapid response to fault conditions, while the thermal overload protection capability (when configured appropriately) provides comprehensive motor safeguarding. Featuring IP20 degree of protection and compact dimensions of 94mm height × 45mm width × 99.6mm depth, the MPX³ represents an efficient solution for motor protection in modern electrical installations.
