6 Frequently Asked Questions about “Factory price d curve breaker”
What is a k & d curve breaker?
The ideal application is a circuit with a motor load. The K and D curve breakers are both designed for motor applications where ampacity rises quickly and momentarily during “start-up.” Both curves can “ride through” the momentary inrush of current and prevent nuisance tripping while providing protection to the circuit.
What are the best breaker circuit breaker products?
Our best selling products are breaker circuit breaker NHP 1 Pole 10amp D Curve MCB Circuit Breaker - DTCB6110D, NHP 1 Pole 16amp D Curve MCB Circuit Breaker - DTCB6116D, NHP 1 Pole 20amp D Curve MCB Circuit Breaker - DTCB6120D and NHP 1 Pole 32amp D circuit braker Curve MCB Circuit Breaker - DTCB6132D .
What is a D-trip circuit breaker?
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit. D-trip circuit breakers prevent nuisance tripping, so they are best for equipment that has a high spike in current at startup, such as transformers, power supplies, and heaters.
What is a supplemental circuit breaker?
Also known as supplemental protectors, these circuit breakers mount directly to DIN rail downstream from a branch circuit breaker to protect a single piece of equipment. They are rated UL1077 for protection against overloads and short circuits. Because they are thermal- magnetic, these breakers trip two ways.
What causes a circuit breaker to trip?
They either trip when heat is generated slowly by consistent low-level overload current, or they trip quickly when the magnetic coil senses a high-current short circuit. Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
How do ul 489 circuit breakers work?
Mount these circuit breakers directly to DIN rail to protect equipment and wiring in an area of your facility from overloads and short circuits. They meet UL 489 requirements for branch circuit protection and are certified as current limiting, so they protect equipment by minimizing passing current during a short circuit.
