Frequently Asked Questions
Q: What is the 334921 contact set and what equipment does it fit?
A: The 334921 is a SB350 2/0 contact set engineered for Anderson Power Products SB350 connectors used in electric lift truck battery and power distribution systems. It is compatible with 2/0 AWG cable installations in Crown, Toyota, Hyster, Yale, and other OEM lift truck models utilizing 600V DC power systems.
Q: What is the current and voltage rating for the 334921 contact set?
A: The 334921 is rated for 350A continuous current with 2/0 wire (450A continuous with 4/0 wire) and up to 600V DC operation. Operational limit is 500V AC/DC. Do not exceed these ratings in service applications.
Q: What material are the 334921 contacts made from?
A: The 334921 contacts are silver-plated copper alloy with spring retention. Silver plating provides superior conductivity and corrosion resistance critical for reliable power delivery in electric lift truck battery systems.
Q: How many mating cycles is the 334921 contact set rated for?
A: The 334921 contact set is spring-retained and rated for 10,000 mating cycles. This specification assumes proper alignment and contact pressure during each connection/disconnection operation.
Q: Is the 334921 equivalent to Anderson Power Products 907 contacts?
A: Yes, the 334921 SB350 2/0 contact set is cross-referenced to Anderson Power Products part number 907. Both are designed for SB350 connectors with 2/0 AWG cable applications in 350A continuous current systems. Verify connector housing compatibility before ordering.
Q: What maintenance does the 334921 contact set require?
A: Periodically inspect contacts for corrosion, pitting, or discoloration during battery and electrical system maintenance. Clean connector mating surfaces with a dry cloth if visible contamination is present. Replace contacts if damage is observed or if connection resistance increases, which can cause voltage drop during equipment operation.
