The KXTARHES500 is an adjustable depth rotary handle rod designed for use with fixed-plug-in circuit breakers in the T4, T5, and T6 series. This component features a 500 mm rod length that enables precise manual operation and control of circuit breaker mechanisms through rotary handle actuation. The rod is engineered for compatibility with ABB/Thomas & Betts Tmax circuit breaker platforms, providing reliable mechanical linkage between the external handle and internal breaker contacts. It is commonly used in industrial electrical distribution systems where manual circuit breaker operation and maintenance accessibility are required.
