Frequently Asked Questions
Q: What is the part number 7827550 and what does it do?
A: The 7827550 is a contact set assembly for SB350 2/0 rated contactors used in electric lift truck motor circuits. Contact sets are the electrically active components within a contactor that complete or interrupt the circuit to the motor. This SKU is a direct replacement for worn or damaged SB350 contact sets.
Q: What lift truck models use the 7827550 contact set?
A: The 7827550 fits electric pallet jacks and lift trucks equipped with SB350 series contactors, including models from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, and other manufacturers. Verify your equipment uses an SB350 2/0 contactor before ordering.
Q: What is the material composition of the 7827550?
A: SB350 contact sets use silver alloy contacts bonded to a backing material. Silver alloy provides excellent electrical conductivity and resistance to arcing. The backing material is typically copper or brass and is designed to dissipate heat generated during switching cycles.
Q: How long does the 7827550 contact set last in service?
A: In typical warehouse or light industrial use, contact sets last 3 to 5 years. Lifespan varies with frequency of motor engagement, load conditions, and ambient temperature. Heavy-use environments or continuous cycling may require replacement in 2 to 3 years.
Q: Are there equivalent parts or cross-references for the 7827550?
A: Cross-reference depends on your contactor OEM and model. The 7827550 is a SB350 2/0 contact set; equivalent parts must be rated for the same contactor type and amperage. Do not assume cross-compatibility with other contact set SKUs without confirming your specific contactor model.
