Product Overview
The Anderson SB 50 Connectors, a design pioneered in 1953, set the standard for DC power distribution and battery connections. These two-pole connectors feature a one-piece plastic housing with stainless steel springs to secure low-resistance contacts. Suitable for wire sizes from 16 to 6 AWG (1.5 to 13.3 mm), the SB 50 offers UL-rated currents up to 120 amps and is UL-rated for hot-plugging up to 50 amps, making it ideal for battery applications where circuit interruption is necessary. The system supports wire, PCB, and busbar contacts, providing a versatile connection solution for diverse needs.
