Description: Store New Arrivals Add to Favorite View Feedback Contact DC Miniature Circuit Breaker, 2 Pole 500V 40 Amp Isolator for Solar PV System Description FUNCTIONS: Used to protect power distribution facilities from overload and short-circuit damage, and can also be used for control and isolation.FAST TRIP: The electromagnetic trip system can trip immediately when the circuit is short-circuited to protect the safety of the circuit.ARC EXTINGUISHING: DC arc extinguishing is more difficult than AC. This DC mini circuit breaker has a magnetic system to assist arc extinguishing.APPLICATION: Used in DC power system, ship electric power system, solar photovoltaic system, or other DC system.INSTALLATION: Screw clamp wires, 35mm DIN rail mount. Product Description Chtaixi DC Miniature Circuit Breaker Warm Tips: Pay attention to polarity.Select wire size according to rated current. 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. Quality Products to Protect Your Electricity Safety 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.
