Frequently Asked Questions
Q: What does SB175 mean and what is the CL 1802443 used for?
A: The CL 1802443 is the Clark OEM version of the SB175 standard 2-pole power connector. It is engineered for battery and charging circuit connections in electric lift truck systems requiring 175 amp continuous current capacity.
Q: What is the maximum voltage and current rating for this red connector?
A: The CL 1802443 is rated for 175 amperes continuous current and 600VDC maximum voltage. This dual-rated specification allows use in both industrial DC power systems and provides safety margin for surge conditions.
Q: Why does this connector have 2 poles instead of 1?
A: The 2-pole design accommodates positive and negative battery connections in a single mated pair. This reduces connection points and improves safety and reliability compared to two separate single-pole connectors.
Q: What material is the housing and contacts on the CL 1802443?
A: The CL 1802443 features a polycarbonate housing rated UL94 V-0 for flame resistance, and silver-plated contacts for high-cycle mating in industrial environments. Red polycarbonate indicates this is a secondary or charging connector by standard electrical convention.
Q: What are the cross-reference part numbers for the CL 1802443?
A: The CL 1802443 cross-references to part number 1802443 and uses the SB175 industry standard designation. If you need a replacement, verify your equipment documentation lists one of these references before ordering.
Q: How does the CL 1802443 perform in heavy-duty industrial applications?
A: The silver-plated contacts and polycarbonate housing are engineered for repeated high-current mating cycles typical of material handling equipment. The 600VDC rating provides protection against electrical transients that occur during rapid charging or load switching.
