Frequently Asked Questions
Q: What are the electrical ratings for the N-130A SB 175 connector?
A: The N-130A is rated for 280 amps (wire-to-wire) or 200 amps (wire-to-busbar) at 600VAC or 600VDC per UL 1977 standard. This industrial-grade connector accommodates up to 1/0 AWG cable and provides robust power connections for high-current applications.
Q: What applications use the N-130A industrial DC connector?
A: The N-130A is designed for battery and lift truck power connections including electric forklifts, electric pallet jacks, and other material handling equipment requiring reliable high-current power distribution. It is also used in backup power systems and industrial battery charger connections.
Q: What makes the N-130A genderless design beneficial?
A: The genderless design of the N-130A allows flexible connection orientation and compatibility across multiple equipment configurations. This feature simplifies maintenance and reduces connector inventory while maintaining mechanical keying by color to prevent incorrect polarity connections.
Q: What contact material is used in the N-130A and why?
A: The N-130A features silver-plated contacts that provide superior electrical conductivity and corrosion resistance. Silver plating ensures consistent low-resistance connections over the connector lifespan, critical for minimizing voltage drop in high-current battery and lift truck applications.
Q: What is the housing material and flammability rating of N-130A?
A: The N-130A housing is constructed from durable polycarbonate with a UL94 V-0 flammability rating, indicating it does not propagate flame and provides superior fire safety. The gray polycarbonate housing resists impact and chemical exposure common in industrial warehouse environments.
Q: How does the color-coded mechanical keying on N-130A work?
A: The N-130A uses color-coded mechanical keying to physically prevent incorrect polarity connections. Different color keys on the connector body and mating surfaces ensure proper positive and negative terminal alignment, protecting equipment from reverse-polarity damage on battery and power systems.
