CONTACT KIT (100 AMP)
Frequently Asked Questions
Q: What is SKU 4905266 and what equipment does it fit?
A: SKU 4905266 is a 100 amp contact kit used in battery charger and power distribution systems for electric lift trucks and pallet jacks. It replaces worn or damaged contacts in Anderson SB50, Powerpole, or similar high-current connectors on Crown, Toyota, Raymond, Yale, Hyster, and comparable equipment. The 100 amp rating supports heavy-duty charging and motor circuits.
Q: What does a contact kit contain and why is replacement needed?
A: Contact kit 4905266 includes replacement male and female contacts, usually in pairs, designed to fit into connector housings. Contacts degrade due to repeated connection cycles, arcing, corrosion, or pitting. Worn contacts cause high resistance, voltage drop, slow charging, or intermittent electrical faults. Replacement restores proper electrical continuity and prevents equipment shutdown.
Q: How do I identify if contacts in 4905266 are needed?
A: Signs of contact failure include slow battery charging, visible sparking or arcing when connecting or disconnecting, discolored or pitted connector surfaces, charger error codes, or intermittent power loss. Measure voltage drop across the connector under load; a drop exceeding 0.5 volts indicates worn contacts. Inspect contact surfaces visually; black discoloration or pitting indicates replacement is needed.
Q: What is the amperage rating and compatibility of 4905266?
A: 4905266 is rated for 100 amps continuous current and supports 24V, 36V, and 48V DC charging and motor circuits. The contacts fit Anderson SB50 connectors and similar high-current housings. Verify your connector housing type and voltage system before ordering to ensure compatibility with your equipment.
Q: How long do replacement contacts like 4905266 last before wear occurs again?
A: Properly installed contacts typically last 5 to 10 years under normal charging and operating cycles. Lifespan depends on connection frequency, load consistency, environmental exposure, and maintenance. In high-duty environments with frequent connect-disconnect cycles, contacts may wear within 2 to 3 years. Keep connectors clean and dry, and apply dielectric grease to extend service life.
