DC resettable circuit breaker

This automatic circuit breaker is an intelligent and reliable solution for protecting your DC systems from overcurrent, overload, and short circuits. It is designed for 12V, 24V, or 48V systems and comes in a wide range of rated currents – from 20A up to 150A, making it extremely versatile for various applications. Unlike one-time-use fuses, this model features a key advantage: it is manually resettable after the fault is cleared, saving both time and replacement costs.

Its operation is based on thermal induction, which provides high sensitivity and fast response when the current threshold is reached. It is ideal for integration into solar power systems, car audio/video setups, protection of charging equipment, and other DC installations. The easy manual ON/OFF switch and intuitive reset mechanism make it user-friendly while retaining the key benefit of automatic protection. This is an essential component for anyone seeking safety and durability for their DC circuits.

The difference with ordinary insurance is the following three points:
1. Its sensitivity is very high, can protect circuit electrical appliances in time
2. After disconnecting and troubleshooting, it can be manually resumed and used manually.
3.It can control high current circuit

100% brand new and high qualityLeakage protection, overload protectionGood conductivity and craftsmanship, high temperature pressure
Instructions for use:

1.If you need to disconnect manually, you can press the manual disconnect button, do not forcibly open the reset wrench, or it will cause the shaft to break.
2.When the power is on, the rated current is reached or close, the circuit breaker will automatically disconnect.

This product uses the principle of thermal induction, so the current when disconnected is not the rated current.

3.After manual disconnection, push the reset wrench can be reset. After the automatic disconnection,

and product has cooled, can push the reset wrench to reset.
