COIL CONTACT

COIL CONTACT 3717 0062 47 Located inside the main electrical cabinet, this contactor coil is the component that receives a low-voltage signal to switch a high-power circuit on or off. When energized, its magnetic field pulls in the main contacts, allowing current to flow to a critical system like the hydraulic power pack motor. Its proper function is fundamental for the entire rig's electrical control logic, translating operator commands into machine action.

A failing coil can lead to significant downtime and frustrating electrical faults. If the coil winding is broken or shorted, the associated motor will fail to start, even if you hear a signal from the control system. An intermittent failure can cause random shutdowns, making it difficult to troubleshoot the root cause. Using a correct, high-quality replacement ensures that electrical circuits switch cleanly and reliably, protecting motors from damage and keeping the rig productive.

Symptoms of a worn-out coil include a loud buzzing or humming from the contactor, overheating, or a complete failure to activate. Before replacement, always ensure the machine is properly locked out and de-energized. Swapping the coil is usually a straightforward task for a qualified electrician, involving the removal of the contactor's cover and carefully fitting the new unit.
