Zhushan 120A Quick Disconnect Battery Connectors Kit — 4pcs Flush-Mount Plates with Dust Covers, SB120-Compatible

Zhushan 4-piece 120A quick disconnect kit provides heavy-duty, flush-mount battery connectors with dust covers for trailers, RVs, solar arrays, trucks and boats.

The Zhushan kit bundles everything needed to install four high-current Anderson SB120-compatible connectors: housings, terminal pins, mounting plates, dust covers, screws and sealing rubbers. Built for demanding power systems, the components use flame-retardant PC housings and silver-plated copper terminals to support up to 120A and 600V while resisting heat and corrosion. The design prioritizes a tidy flush fit and protection from dirt and moisture so connections remain reliable in mobile and outdoor environments.

How do these connectors handle high-current power demands?

These connectors are rated to 120A and 600V and accept 2/4/6 AWG cable, making them suitable for heavy loads like winches, batteries and inverter feeds. Silver-plated copper terminals lower contact resistance and improve conductivity under continuous load.

• 120-amp continuous rating for high-load circuits
• 600V maximum voltage rating for versatility
• Compatible with 2/4/6 AWG cable sizes
• Silver-plated copper terminals reduce heat and power loss

What makes installation and mounting clean and durable?

The kit includes two embedded flush-mount panels that let you recess connectors into flat surfaces for a tidy, professional appearance. All necessary screws and sealing rubbers are supplied so you can secure terminals, fasten plates and seal openings against moisture.

• Flush-mount plates for neat panel installation
• Included mounting screws and fixing hardware
• Sealing rubbers to limit moisture ingress
• Clear installation workflow—no extra parts required

How do the dust covers and materials protect connections?

Protective dust covers shield inactive plugs from dirt, corrosion and salt spray, extending service life in marine and roadside conditions. The housings are made from flame-retardant PC and terminals are corrosion-resistant, balancing safety with long-term performance.

• Two dust covers provided for unused connectors
• Flame-retardant polycarbonate housing for thermal safety
• Silver-plated copper terminals resist corrosion
• Durable under wet, salty or dusty conditions

Can this kit be used across different vehicles and systems?

Yes—the kit’s design mirrors Anderson SB120 compatibility and is versatile for trailers, RVs, trucks, boats and solar setups. Its robust ratings and supplied hardware make it suitable for mobile power, auxiliary battery feeds and portable equipment connections.

• Compatible with Anderson SB120-style devices
• Works for trailers, RVs, boats, trucks and solar arrays
• Useful for winches, battery banks and inverter connections
• Ideal where reliable, repeatable quick-disconnects are needed

Who is this for: Installers, DIYers and fleet owners who need a compact, heavy-duty quick-disconnect solution for 120A circuits will value this Zhushan kit. It’s aimed at people fitting or upgrading electrical panels, battery compartments and external access points on trailers, RVs, marine vessels, trucks and off-grid solar systems who want a neat flush installation and protection against corrosion and contamination.
