Baintech BTA503-PACK 3 Pack Anderson Plugs 50A Red Blue Grey

Colour-coded 50A connections for trailer, boat, and auxiliary power systems

The Baintech BTA503-PACK is a 3-pack of 50A Anderson-style plugs supplied in red, blue, and grey colours for easy circuit identification. Each plug features a 2-way design with locking mechanism that secures connections between cables, preventing accidental disconnection during use. Rated at 50A capacity, these connectors suit trailer power connections, boat electrical systems, and auxiliary power distribution in 4WD and caravan setups.

The colour-coding system enables quick visual identification of different circuits, simplifying installations where multiple Anderson connections are used for battery charging, auxiliary equipment, or accessory power feeds.

Features & Benefits

3-Pack Colour Variety — Red, blue, and grey plugs in one pack enable colour-coded circuit identification across multiple connections, ideal for systems with separate solar charging, auxiliary battery, and accessory circuits that require quick visual differentiation.

50A Current Rating — Handle substantial current loads suitable for trailer brake controllers, auxiliary battery charging, portable fridge connections, and boat accessory power without voltage drop or overheating on extended runs.

Secure Locking Design — Anderson-style locking mechanism prevents accidental disconnection during vehicle movement, rough terrain travel, or marine conditions where vibration and impact could separate standard connectors.

2-Way Plug and Socket Configuration — Each connector includes both plug and socket halves for complete cable-to-cable connections, eliminating the need to purchase separate components for trailer-to-vehicle or auxiliary power installations.

Trailer and Boat Applications — Purpose-designed for connecting trailers, boats, and auxiliary equipment where reliable high-current connections are essential for brake systems, lighting, and accessory power feeds.

Multi-Circuit System Organization — Three different colours allow systematic circuit identification in complex setups, such as differentiating between solar input (blue), battery output (red), and accessory circuits (grey) in caravan electrical systems.

Frequently Asked Questions

What size cable do these Anderson plugs accept?

Not specified in product information; verify compatible cable gauge with manufacturer documentation before purchase.

Do these come pre-wired or require cable termination?

Not specified; these appear to be connector housings that require cable attachment through crimping or soldering methods.

Can I use different colours for different voltage systems?

These are all rated 50A at the same voltage capacity; colour selection is for circuit identification purposes only, not voltage differentiation.

Are these compatible with standard Anderson plug systems?

These are Anderson-style plugs; verify compatibility with your existing Anderson connector system if mixing brands or connector types.

What applications are best suited for each colour?

Colour selection is user preference; common practices include red for battery positive circuits, blue for solar input, and grey for auxiliary loads or neutral applications.
