Frequently Asked Questions
Q: What is the intended application for contact BJ 903024?
A: BJ 903024 is a high-amperage auxiliary contact rated for 120-volt DC systems with 450-amp sustained capability. This contact handles steering and hydraulic pump circuits in larger capacity electric lift trucks.
Q: Which equipment models use contact BJ 903024?
A: BJ 903024 is compatible with Toyota 8FDU35 and 8FGDU40 series, Crown SC8000-SC10000 forklifts, and Jungheinrich EFG435-435k models. Verify your equipment manual before ordering.
Q: What is the amperage and voltage specification for SKU BJ 903024?
A: BJ 903024 is designed for 120-volt DC systems with a continuous amperage rating of 450 amps. Do not use this contact on lower-voltage systems as it is oversized for those applications.
Q: What material composition makes this contact different from BJ 903022 and BJ 903023?
A: BJ 903024 uses a triple-layer silver plating on a copper alloy base with enhanced phenolic resin backing designed for high heat dissipation. This construction handles the elevated amperage and thermal cycling of large truck hydraulic circuits.
Q: What failure signs require immediate contact replacement?
A: Replace BJ 903024 immediately if you observe pitting deeper than 0.020 inches, charring on the contact face, steering control lag, or intermittent hydraulic function. These symptoms indicate arcing damage that worsens rapidly without replacement.
Q: Are cross-reference part numbers available for BJ 903024?
A: Cross-reference equivalents include Toyota part 27300-23820-71 and Crown part 82620-4. BJ 903024 is the OEM-equivalent aftermarket replacement. Match your specific equipment model and voltage before ordering.
