Frequently Asked Questions
Q: What is the difference between the 253979 blue housing and 253977 gray housing?
A: Both 253979 (blue) and 253977 (gray) are SB350 housings with identical electrical specifications: 600V DC/AC rating, 450A maximum capacity with 4/0 AWG, and 350A nominal with 2/0 AWG. Color is used for visual field identification only. Electrical and dimensional compatibility is the same.
Q: Which contact sets are compatible with the 253979 blue SB350 housing?
A: The 253979 blue housing accepts all standard SB350 contact sets including the 253978. Contact compatibility is determined by connector series (SB350) and cable gauge rating, not housing color. Verify contact rating matches your application amperage.
Q: What is the rated voltage and amperage of the 253979?
A: The 253979 SB350 blue housing is rated at 600 volts DC and AC. Current capacity is 450 amperes maximum with 4/0 AWG cable or 350 amperes nominal with 2/0 AWG cable. Do not exceed these ratings to prevent contact damage and thermal runaway.
Q: Is the 253979 housing chemical-resistant or standard polyurethane?
A: Product specifications do not indicate the 253979 blue housing is chemical-resistant. If your application requires protection from battery acid or harsh chemicals in cold storage or battery rooms, verify chemical-resistance rating in detailed product documentation or contact us for compatibility information.
