2P Miniature Circuit Breakers

2P Miniature Circuit Breakers

SDKC's 2P miniature circuit breakers (hereinafter referred to as circuit breakers) are mainly used for AC 50/60Hz, rated voltage up to 600V, current up to 63A, with short circuit protection, overload protection, control, isolation and other functions, suitable for industrial and commercial lighting line low-voltage terminal distribution, industrial, civil buildings, energy, communications, infrastructure and other fields of AC and DC system protection.

Product advantages: The 2P miniature circuit breakers produced by SDKC are small and convenient, safe and reliable, energy-saving and environmentally friendly, durable, and high-quality circuit breakers ensure your electricity safety.

1. Design features: full current specifications, high breaking capacity, suitable for high and low temperature environments, safer flame-retardant materials, precise protection characteristics, small size and fast closing speed, and long mechanical and electrical life.

2. Installation category: This circuit breaker is embedded, with a clamping rail on the back, convenient and reliable wiring, and can be equipped with a variety of accessories. The function expansion is simple, modular, and can be combined arbitrarily.

3. Main structure and working principle: The circuit breaker is mainly composed of a shell, an operating mechanism, an instantaneous release, an arc extinguishing device, etc. The moving contact of the circuit breaker can only stay in the closed or disconnected position; the moving contact of the multi-pole circuit breaker should adopt mechanical linkage, and each pole can be closed or disconnected at the same time; when installed vertically, when the handle moves upward, the contact moves in the closing direction.

Installation method

Use TH35-7.5 steel mounting rail for installation.

It has isolation function and can be used as an isolation switch to disconnect the line, facilitating line and equipment maintenance.

Q: What is the wiring method of 2P miniature circuit breaker?

A: The upper end is connected to the power supply, and the lower end is connected to the load, ensuring that the live wire and the neutral wire are correctly connected.

Q: What does the number of poles of 2P miniature circuit breaker mean?

A: The number of poles refers to the number of lines controlled by the circuit breaker. Conventional 2P means that both the live wire and the neutral wire are controlled at the same time.

Q: Can 2P miniature circuit breaker be used in DC circuit?

A: Yes, special customized DC miniature circuit breaker is required. Miniature circuit breakers are usually designed for AC circuits, and DC circuits require special DC circuit breakers.

Q: Does 2P miniature circuit breaker have leakage protection?

A: Ordinary 2P miniature circuit breakers do not have leakage protection, and a leakage protection device (RCBO) needs to be installed additionally.

Q: How long is your delivery time?

A: Depending on your order quantity, generally within 12 days after receiving the deposit.

Q: Where is your factory located?

A: Zibo City, Shandong Province, China.

Q: How to reset a 2P miniature circuit breaker after it trips?

A: After tripping, first turn the switch to the "OFF" position, then turn it back to the "ON" position to reset it. If it trips frequently, you need to check whether the circuit is faulty.

Q: Can we get samples?

A: Of course. We can provide free samples.

Q: How do you guarantee product quality?

A: Every product produced in our factory undergoes a strict testing procedure and must be 100% qualified before delivery. We believe in doing the best.
