Circuit breaker 5 ampere

Automatic circuit breaker for electrical protection

Automatic circuit breaker with 5 ampere capacity, essential for protecting low-voltage circuits in 6V and 12V electrical systems. This resettable fuse protects against overload and short circuits by means of a thermal or electromagnetic mechanism.

Capacity

5 ampere

Type

Automatic circuit breaker

Function

Resettable, thermal

Application

Low-voltage circuits

Features

  • 5 ampere capacity for small electrical circuits
  • Automatically resettable after cooling
  • Compact design for mounting behind dashboard
  • Thermal or electromagnetic cut-out during overload
  • Suitable for 6V and 12V systems

★ Reliable protection of electrical circuits against short circuits and overload. Widely used in classic military vehicles for protecting instrumentation and small consumers.

Application

This 5 ampere circuit breaker was originally applied for protecting fuel gauge circuits and other low-voltage circuits. Suitable for installation behind the dashboard on a bracket, in combination with other circuit breakers (typically together with a 15 ampere unit).

Installation notes

Mount on a suitable bracket behind the dashboard or near the circuit to be protected. Connect in series with the circuit to be protected. During overload the breaker automatically cuts out and can be reset after cooling by pressing the button.

Compatibility

Please note: this 5 ampere variant is specifically intended for circuits with low current draw such as fuel gauges, instrumentation or signal lights. Use heavier duty versions (15 ampere) for horn circuits and lighting circuits. Not suitable for high-power circuits such as starters or headlights.

Historical context

Circuit breakers were added to military jeeps during WWII in later production series to reduce fire hazard from electrical short circuits. The 5 ampere variant specifically protected sensitive measuring instruments.
