Frequently Asked Questions
Q: What is the difference between the wire-to-wire and wire-to-busbar current ratings?
A: The 49130 SB175 connector housing is rated 280A wire-to-wire (1/0 AWG to 1/0 AWG connections) under UL 1977, but only 200A wire-to-busbar (1/0 AWG cable to copper busbar). Use the wire-to-busbar rating of 200A when connecting battery cables to main contactor busbars in electric lift trucks to ensure safe operation within UL certification limits.
Q: What OEM part number is the 49130 equivalent to?
A: The 49130 is the equivalent to OEM part number 942. It is a SB175 connector housing with orange keying for 1/0 AWG cable, designed for high-current DC applications in electric material handling equipment.
Q: What is the maximum insulation diameter for the 49130?
A: The 49130 accommodates wire with a maximum insulation diameter of 0.600 inches. This limits use to 1/0 AWG cable and smaller. For larger conductor sizes, a larger connector housing is required.
Q: What voltage rating does the 49130 connector housing provide?
A: The 49130 is rated 600V AC or DC under UL 1977, with silver-plated copper contacts for superior conductivity and corrosion resistance. The orange keying is a safety feature to prevent voltage mismatch in multi-voltage fleets operating both 24V and 80V systems.
Q: Can the 49130 be used in chemical-resistant applications?
A: The 49130 features a polycarbonate housing suitable for harsh warehouse environments. For extreme chemical resistance, optional chemical-resistant housing variants are available. Verify application requirements before ordering if exposure to solvents, acids, or cleaners is expected.
