Frequently Asked Questions
Q: What are the electrical specifications for the 916781 connector?
A: The 916781 (SB175) is rated for 280 amps maximum at 1/0 AWG wire-to-wire per UL 1977, and 175 amps per CSA. Maximum voltage rating is 600 VAC/DC. The connector features silver-plated copper contacts and a UL94 V-0 flame-rated polycarbonate housing with a thermoplastic elastomer environmental boot.
Q: What equipment types use the 916781 connector?
A: The 916781 is designed for electric lift truck and battery applications. The self-mating genderless design and color-keyed polycarbonate housing make it suitable for high-amperage DC battery circuits on electric forklifts, electric pallet jacks, and electric tow tractors from Crown, Toyota, Raymond, Yale, and similar OEMs.
Q: Is the 916781 equivalent to any other part numbers?
A: Yes. The 916781 is cross-referenced as SB175 and 949. All three designations refer to the same connector assembly. Verify your equipment documentation or existing connector to confirm fitment before ordering.
Q: Why does the 916781 have silver-plated copper contacts?
A: Silver plating improves electrical conductivity and corrosion resistance on the copper contact surfaces. This is critical for high-amperage battery applications where poor contact can cause voltage drop, heat generation, and equipment failure. The material composition ensures reliable performance in wet and cold storage environments common to material handling operations.
