Frequently Asked Questions
Q: What is the difference between the 7827501 and other SB350 contact sets?
A: The 7827501 is a contact set assembly for SB350 2/0 rated contactors. Variations between SKUs in this series typically relate to the specific contactor generation, mounting orientation, or contact surface finish. Verify your exact contactor model and serial range to ensure the correct SKU.
Q: Which equipment models accept the 7827501?
A: The 7827501 contact set fits electric pallet jacks and lift trucks from Crown, Toyota, Raymond, Yale, Hyster, and other manufacturers that use SB350 series contactors rated for 2/0 gauge motor circuits. Confirm your truck uses an SB350 contactor before ordering.
Q: What causes contact sets to fail?
A: Contact sets fail due to repeated electrical arcing, pitting from high-current switching, contamination from motor brush dust, or moisture exposure. Signs of failure include slow motor acceleration, inconsistent power delivery, or visible damage to contact surfaces. Replace contact sets if these symptoms appear.
Q: How can I tell if a contact set needs replacement?
A: Inspect the contact surfaces for pitting, discoloration, or erosion. If the contactor chatters when energized, the motor responds slowly to throttle input, or you see arcing inside the contactor housing, the contact set requires replacement. Do not defer replacement, as worn contacts reduce motor efficiency and accelerate further damage.
Q: Is the 7827501 compatible with SB175 or SBX175 contactors?
A: No. The 7827501 is rated for SB350 2/0 contactors only. Do not use this contact set in SB175, SBX175, or other contactor models. Each contactor type requires contact sets matched to its amperage, voltage, and physical specifications.
