Auxiliary contact for P&H 5 ton

The auxiliary contact 479U165D16 functions as a secondary switching device within the electrical control circuits of P&H cranes. It provides additional signals for control logic, safety interlocks, and status indication for the primary contactor or relay. By operating within low-current control circuits, this component facilitates the correct sequencing of operations and contributes to the overall protection of the equipment. It is designed to integrate into the existing electrical architecture of the crane to ensure precise interaction between various machine subsystems.

This component is compatible with P&H 5 ton and 8 ton crane models. It is engineered to meet the electrical specifications required for control circuit signaling in these specific crane configurations. The part ensures that the control system receives accurate feedback regarding the state of primary electrical components, which is necessary for the safe operation of the crane functions.

Auxiliary contacts are used in industrial machinery to extend the functionality of primary power switches. They allow the control system to monitor the position of a contactor or relay, enabling automated sequences and safety protocols that prevent hazardous operations. These contacts are typically mounted to the side or top of a main contactor and actuate simultaneously with the main power contacts.
