Frequently Asked Questions
Q: What cable gauge and current rating does the 253978 contact set support?
A: The 253978 is a contact set for SB350 connectors with a maximum rating of 450 amperes with 4/0 AWG cable and 350 amperes nominal rating with 2/0 AWG cable. Do not exceed these ratings to prevent contact overheating and failure.
Q: What are the cross-reference part numbers for the 253978?
A: The 253978 is equivalent to Anderson parts 907-BK, 350-CON-2-0, and industry cross-reference 123108-001. These part numbers refer to identical SB350 contact sets rated for 2/0 AWG nominal. Verify manufacturer part number 907-BK when sourcing equivalent replacements.
Q: Are the 253978 contacts silver-plated?
A: Yes. The 253978 contact set features high-force silver-plated copper contacts. Silver plating reduces contact resistance and improves conductivity under heavy load cycling. Silver plating also resists oxidation compared to bare copper contacts.
Q: Can the 253978 contact set be used with both standard and chemical-resistant SB350 housings?
A: Yes. The 253978 contact set is compatible with both standard gray SB350 housings and chemical-resistant SB350 housings. The contact terminal design is identical regardless of housing material or color. Verify housing compatibility with your equipment before ordering.
Q: Does the 253978 accept crimp or set-screw termination?
A: The 253978 accepts both crimp and set-screw termination methods. This flexibility allows use with different cable preparation techniques. Confirm your termination method matches equipment wiring specifications.
