The 48-Series push-to-reset thermal circuit breaker is designed for low to mid-range current protection. With ratings from 3A to 50A, it’s ideal for a wide range of AC and DC applications, including marine, automotive, and industrial systems.

• Voltage support: 125/250V AC or 32/50V DC

• Amperage range: 3A–50A

• Protection: Consistent performance across a wide range of overload conditions

The 48 Series breaker is engineered with a precise trip curve that balances protection and reliability across its full 3–50 amp range.

• 3–30A Range

  • Holds at 100% overload

  • Resists tripping for 60 minutes at 150%

  • Trips within 5–28 seconds at 200%

  • Trips rapidly within 1.8–5.5 seconds at 300%

• 31–50A Range

  • Holds at 100% overload

  • Resists tripping for 60 minutes at 150%

  • Trips within 7.8–40 seconds at 200%

  • Trips rapidly within 3.2–7.7 seconds at 300%

The 48-Series breaker is built for flexibility and space efficiency. It supports panel or plate mounting, secure ring nut installation, and can be paired with optional black or clear boots for added environmental protection.

Connection options include .250” quick-connect tabs or 90-degree screw terminals, while customizable tops in black, white, or clearly marked caps make integration simple.

With 0.1″ mounting holes spaced 0.44″ apart, the compact design saves valuable space and fits seamlessly into 6 or 12-position breaker boxes for clean, modular circuit organization.
