£172.60
The IMO C4/63R-26 is a high-performance thermal magnetic motor circuit breaker designed to provide dependable protection for three-phase motors in industrial machinery, automation systems and motor control panels. As part of the IMO C4 motor protection circuit breaker range, it combines adjustable thermal overload protection with rapid magnetic short-circuit protection, helping to maximise equipment reliability whilst reducing costly downtime.
Designed for machine builders, panel manufacturers and maintenance engineers, the C4/63R-26 protects motors against overloads, short circuits and phase failure conditions. Its robust rotary operating mechanism, compact design and DIN rail compatibility make it suitable for demanding industrial environments requiring reliable motor starting and protection.
With an adjustable thermal setting of 18-26 A and an instantaneous magnetic trip of 338 A, the IMO C4/63R-26 is ideal for protecting larger motors used in pumps, compressors, conveyors, fans and production machinery.
The IMO C4/63R-26 combines thermal overload and magnetic short-circuit protection in a single compact device, allowing accurate protection of three-phase motors whilst reducing the need for separate protective equipment. The adjustable overload setting enables the breaker to be matched precisely to the motor's full-load current for dependable operation.
Its robust construction and accessory compatibility make it suitable for OEM machinery, industrial control panels and motor starter assemblies where reliable motor protection and isolation are essential.
