120A Anderson Plug | SB120 Compatible | Heavy-Duty DC Connector | 12V 24V 48V

Step up to the 120A Anderson style connector when your application demands more grunt than a

50A can deliver. Rated at 120 amps continuous and 600V DC, the SB120-style connector is the

right choice for large lithium battery banks, high-output solar charge controllers, electric vehicle

conversions, industrial DC bus connections, and any wiring run requiring serious current capacity

on 25mm² cable.

When you're running a large LiFePO4 bank, a high-output alternator setup, or industrial DC

equipment, the 50A connector is the bottleneck — not the cable. The 120A Anderson style

connector handles the load your system is actually producing, with the mechanical keying to

ensure it never gets crossed with a lower-rated connector by mistake.

Key Features

• 120A continuous current rating — handles heavy DC loads a 50A can't safely carry

• 600V DC rated — suitable for 12V, 24V, 48V, and higher-voltage DC systems

• Genderless / hermaphroditic design — identical connectors both ends

• Silver-plated copper contacts — high conductivity, self-wiping action cleans contacts on

each connect cycle

• Mechanically keyed housing — cannot mate with 50A, 175A, or 350A connectors

• Impact-resistant polycarbonate housing — rated for industrial and mobile environments

• Operating temperature: -20°C to +105°C

• Suits 2AWG / 25mm² cable

• Flat-wiping contact system — reduces resistance and extends connector life

Ideal Applications

• Large lithium (LiFePO4) battery banks and battery management systems

• High-output MPPT solar charge controllers (60A–100A output)

• Industrial machinery and mobile equipment DC feeds

• Electric vehicle (EV) and electric forklift charging connections

• UPS (uninterruptible power supply) battery bus connections

• High-current alternator outputs and DC power distribution

• Off-grid and hybrid solar power systems

• Marine high-load DC applications
