Frequently Asked Questions
Q: What are the current and voltage ratings for the AN251 connector?
A: The AN251 Anderson SB175 connector with 1/0 AWG contacts is rated for 280 amps wire-to-wire under UL 1977 standards, and 175 amps under CSA standards. Voltage rating is 600V AC/DC continuous. This high-current capacity makes it suitable for main battery and charger power distribution in electric lift trucks.
Q: What wire sizes work with the AN251?
A: The AN251 is designed for 1/0 AWG wire. Using undersized or oversized wire reduces contact pressure and increases voltage drop and heat generation. Always crimp 1/0 AWG contacts to the wire gauge specified for this connector.
Q: Is the AN251 genderless and what does that mean for compatibility?
A: Yes. The AN251 features a genderless design with color-keyed polarization (red housing), meaning either connector half can mate with the other. This reduces confusion during maintenance and service on Crown, Toyota, Raymond, Yale, Hyster, and other electric lift truck charging and battery distribution systems.
Q: What contact material does the AN251 use and why is it important?
A: The AN251 features stainless steel spring contacts for reliable power transfer. Stainless steel resists corrosion from moisture, salt spray, and humidity exposure typical in cold storage, outdoor, and wet-floor environments. This extends contact life and maintains consistent electrical performance.
Q: What applications is the AN251 designed for in lift truck systems?
A: The AN251 SB175 connector is designed for battery power output, charger input, and main equipment power distribution circuits in electric lift trucks. The high current rating (280A UL 1977) makes it suitable for direct battery connections where voltage drop and heat must be minimized.
Q: How does the one-piece housing design affect durability?
A: The one-piece polycarbonate housing eliminates assembly seams and weak points, improving impact resistance and environmental sealing. This design is more durable than multi-part housings in high-vibration material handling environments and reduces moisture ingress around contact areas.
