Introduction to Langir 3-Pole DC Circuit Breaker

Langir is your reliable provider of high-performance and dependable 3-pole DC circuit breakers from China.

Their 3-pole DC circuit breakers are meticulously engineered to ensure world-class quality, long-lasting performance, and high reliability.

The 3-pole DC circuit breaker is essentially three separate 1-pole DC circuit breakersintegrated together with five terminals.

This also means that a 3-pole DC circuit breaker has three separate switches that operate in unison when necessary.

3P DC Circuit Breaker

Working Principle

A 3-pole DC circuit breaker is a switch that quickly cuts off the electrical flow when an issue such as overload, short circuit, or power surge occurs.

This device acts as a protective shield, safeguarding electrical equipment or appliances from potential damage caused by electrical faults.

Such electrical damage can cause equipment or appliances to overheat or burn out, leading to costly repairs or replacements.

Unprotected circuits can be quite expensive, and over a year, the costs may accumulate significantly, potentially causing financial strain.

Applications of 3P DC Circuit Breaker

3-Pole DC Circuit Breaker vs. 4P DC Circuit Breaker

Langir's 3-pole DC circuit breakers function similarly to single-pole DC circuit breakers.

However, the difference lies in the fact that 3-pole DC circuit breakers have more connected or bridged conductors and are commonly used in three-phase electrical systems.

When a surge occurs anywhere in the electrical system, the 3-pole DC circuit breaker trips, breaking the bridge and opening the circuit.

While 3-pole DC circuit breakers are used in high-power applications, 4P DC circuit breakers are required when there are two alternative power sources.

In the event of a power failure, the standby generator takes over.

When protection is connected to neutral and not grounded, it is best to use 3-pole DC circuit breakers, whereas 4P DC circuit breakers are ideal when the protection is grounded.
