The 38-Series is a compact push-to-reset thermal circuit breaker designed for low to mid-range current protection, with available ratings from 3A to 30A. Ideal for a variety of AC and DC applications, it supports systems up to 125/250V AC or 32/50V DC and delivers consistent performance across a wide range of overload conditions.

This breaker features multiple mounting options, including panel or plate mounting, ring nuts, and optional black or clear boots for added environmental protection. It comes with either .250” quick-connect tabs or 90-degree screw terminals, giving you flexibility during installation. Top styles are also customizable, with black, white, and clearly marked cap options to match your panel setup.The 38-Series also fits seamlessly into our 6 or 12 position breaker box, allowing for clean, modular circuit organization.

With a trip curve designed for safety, the breaker will hold at 100% overload, resist tripping for 60 minutes at 150%, trip within 5 to 30 seconds at 200%, and trip rapidly—within 1.5 to 5 seconds—at 300%.

Mounting holes measure 0.1″, spaced 0.44″ apart, and the compact design allows for efficient use in tight spaces. When paired with our circuit breaker box, the 38-Series can be integrated into a 6 or 12 position distribution panel for streamlined circuit management.
