38-Series Thermal Circuit Breaker

The 38-Series is a small, reliable push-to-reset circuit breaker that protects your electrical system from overloads. It’s available in ratings from 5,10,15,20 amps and works with both AC (up to 125/250V) and DC (up to 32/50V) systems — perfect for many marine, automotive, and RV applications.

This breaker offers flexible installation options, including panel or plate mounting, and can be fitted with black or clear protective boots for extra durability.

It also fits perfectly into our 6- or 12-position breaker box for neat, modular circuit organization:

For safety, the breaker’s trip performance is precisely tuned:

    •    Holds steady at 100% load

    •    Resists tripping for 60 minutes at 150% load

    •    Trips in 5–30 seconds at 200% load

    •    Trips quickly (1.5–5 seconds) at 300% load

Its compact size (0.1″ mounting holes spaced 0.44″ apart) makes it easy to use in tight spaces and ideal for building organized power panels.
