Warm Tips:

  • Pay attention to polarity.
  • Select wire size according to rated current.

DC solar circuit breaker Magnetic Arc ExtinguishingDC solar circuit breaker Magnetic Arc Extinguishing

Magnetic Arc Extinguishing

AC has a zero-crossing point, but DC does not, so DC arc is more difficult to extinguish than AC arc, which is why AC circuit breakers can not be used for DC power, and DC circuit breakers can be used for AC power. This DC mini circuit breaker is equipped with a magnetic field system under the breaking contacts, which can pull the arc to the arc extinguishing chamber to assist arc extinguishing.

Polarity Marked

This DC MCB has no polarity requirement in use, and the positive and negative poles can be inverted. However, the installation, use, and maintenance of DC circuits are based on polarity requirements. So, in order to provide reliable indication and reference for the distribution, we highly recommend that you connect the wires according to the marked polarity.

Tunnel Terminal

The clamping design of the terminal block is designed to connect firmly, and the tightening torque is 2.5 N.m. ( Soft silicone wire needs to crimp fixed the wire end with copper crimp before wiring. ) Make sure that the wires are tightly connected when connecting to prevent loosening and heating. The surface of the terminal is tin-plated, and the plating layer can improve conductivity, corrosion resistance, and durability.

Silver Alloy Contacts

Contacts are very important to circuit breakers, especially for DC distribution with high arc extinguishing requirements. Good contacts can reduce the heat generated by arcing during disconnection and reduce the wear of the contacts. This DC circuit breaker uses silver alloy contacts, which improves electrical durability, and protects your electricity safety for a long time.
