Frequently Asked Questions
Q: What is the amperage rating for connector SKU 277443700?
A: The SB 350A 2/0 Gray connector is rated for 450 amperes continuous with 2/0 AWG wire, or up to 500 amperes with 350 mcm cable. This rating applies at 600V continuous AC or DC in standard industrial conditions.
Q: What wire gauges and conductor sizes fit connector 277443700?
A: This connector accommodates 2/0 AWG through 350 mcm (thousand circular mils) conductors. The 2/0 designation matches the connector size designation. Verify your cable diameter and insulation thickness fit the connector inlet before installation.
Q: Is connector 277443700 suitable for DC power in electric lift trucks?
A: Yes. The SB 350A connector is rated 600V continuous for both AC and DC applications. It is commonly used in electric lift truck main power circuits, battery charger connections, and high-current DC distribution systems. Confirm voltage and amperage match your equipment requirements.
Q: What contact material does connector 277443700 use?
A: The connector features silver-plated contacts for low electrical resistance and durability. Silver plating reduces voltage drop, heat generation, and corrosion at high amperage, making it ideal for heavy-duty DC power applications in material handling equipment.
Q: Does connector 277443700 come in chemical-resistant housing?
A: Yes. The one-piece housing is available in standard polycarbonate (PC) or chemical-resistant PBT/PC blend. Choose chemical-resistant housing if the connector operates in environments with exposure to solvents, cleaners, or harsh temperatures.
Q: Is connector 277443700 compatible with other brands of heavy-duty power connectors?
A: The SB 350A 2/0 Gray connector is a standard form factor in electric lift truck power distribution. Verify connector type and pin configuration match your equipment harness before ordering. We can help identify compatible alternatives if you are upgrading or replacing existing connectors.
