Frequently Asked Questions
Q: What is the function and application of contact 511869804-GE?
A: Contact 511869804-GE is a replacement electrical contact assembly used in DC magnetic contactors for electric forklifts and lift trucks. Contacts are wear components that deteriorate due to electrical arcing during switching cycles and require periodic replacement to maintain reliable power switching.
Q: What is the current rating for this contact?
A: Contact 511869804-GE is designed for use in contactors handling significant electrical loads in battery-powered material handling equipment. The contact is rated for the amperage class of its parent contactor. Verify the amperage specification of your contactor to ensure this contact is appropriate for your electrical switching requirements.
Q: What material composition provides the electrical performance of this contact?
A: Industrial DC contacts use silver alloy or copper alloy compositions to provide low electrical resistance and resistance to arcing erosion. Contact 511869804-GE is manufactured with heavy-duty contact materials suitable for the intermittent high-current switching cycles typical of electric lift truck motor and pump control circuits.
Q: What failure symptoms indicate this contact needs replacement?
A: Signs of contact wear include visible pitting or erosion on the contact surface, intermittent power supply to motors or pump circuits, delayed equipment response to control inputs, or high electrical resistance causing voltage drops across the contactor. These symptoms indicate contact degradation and replacement is needed.
