Frequently Asked Questions
Q: What are the electrical specifications for the 3057428 contact kit?
A: The 3057428 Contact Kit is rated for 100A continuous current at voltages up to 600VDC. The coil voltage range is 9 to 36VDC with a coil average holding current of 0.2A. These ratings apply to General Electric EV-100 contactor applications.
Q: What type of contactor does the 3057428 contact kit fit?
A: The 3057428 is a Contact Kit designed for General Electric EV-100 contactors. It is compatible with EV-100 contactor units rated for 100A continuous operation at up to 600VDC in electric lift truck and industrial applications.
Q: What contact configuration does the 3057428 provide?
A: The 3057428 includes silver alloy SPST-NO (Single Pole Single Throw Normally Open) contacts designed for high cycle performance. These contacts are optimized for reliable switching in electric industrial equipment with frequent on/off cycling.
Q: What are the cross-reference part numbers for the 3057428?
A: The 3057428 cross-references to KIT-3028, EV-100, and 150AA. The part is designated OEM Part Number EV100. KIT-3028 replaces both EV-100 and 150AA. Verify the correct cross-reference before ordering.
Q: What material are the 3057428 contacts made from?
A: The 3057428 contacts are composed of silver alloy. Silver alloy contacts are selected for their excellent electrical conductivity, low contact resistance, and extended life under high-cycle switching conditions in electric industrial equipment.
Q: Can the 3057428 contact kit be used in applications exceeding 600VDC?
A: No. The 3057428 is rated for a maximum of 600VDC. Using this contact kit in higher voltage applications will damage the contacts and compromise electrical safety. Verify your contactor voltage rating matches the 3057428 specification.
