Description
xThe Fastronix Solutions 300A 1/2 in Severe Duty Battery Disconnect Switch with Face Plate delivers rugged, dependable battery isolation for 12V DC systems. Built to withstand demanding environments, this switch pairs heavy copper main studs with a compact, easy to install package. It supports either single pole or dual pole configurations, giving you flexible control for diverse wiring layouts.
Key construction details include 1/2 inch copper main studs rated to 300A continuous and 2000A intermittent, so you can handle substantial load swings without frequent retightening. The compact body includes an index pin that prevents rotation after installation, helping to maintain a clean, secure fit over time. An optional set of smaller auxiliary studs rated to 20A at 12VDC gives you a dedicated path for an indicator light or a small accessory, keeping your primary circuit uncluttered.
For a professional, turnkey installation, pair the switch with Fastronix 404-116 terminal covers. The combination creates a finished look and protects wiring from debris and accidental contact, while preserving easy access to the main disconnect. This product is designed to be part of a scalable electrical setup, where reliable power control matters but exact outcomes will depend on your specific configuration and usage.
Why consider this switch for your project
- High current capacity with 300A continuous rating and 2000A intermittent bursts, enabling robust battery isolation when needed.

A face plate keeps the assembly looking intentional and reduces the chance of accidental contact with live terminals. While this description highlights notable benefits based on the listed features, results will vary with installation conditions and system design.
