2P Leakage Miniature Circuit Breaker

The 2P leakage miniature circuit breaker is a circuit protection device integrating safety protection, intelligent identification and high-efficiency performance.

1. Intelligent Fault Identification: The 2P leakage miniature circuit breaker is equipped with a leakage reset button, supports manual switching on and off, can intuitively distinguish the tripping causes such as short circuit, overload and leakage, quickly lock the fault point, greatly simplify the line maintenance process, and improve the electricity safety and troubleshooting efficiency.

2. Durability and Reliability: The miniature leakage circuit breaker is made of high-strength and high-temperature-resistant composite materials, with excellent impact resistance, and can adapt to a wide temperature environment of -20℃~+60℃; the independently developed new lever arc extinguishing mechanism significantly enhances the arc extinguishing capacity. The mechanical life is 20,000 times and the electrical life is 2,000 times, far exceeding the industry standards, ensuring stable and reliable long-term use.

3. Humanized Detail Design: The red and green dual-color visual window displays the contact status in real time (red for disconnection, green for closing). With clear parameter marks and embedded back rail installation, it ensures convenient installation and intuitive operation; the standard test button supports one-key monthly detection function to ensure that the leakage protection performance of the 2P leakage miniature circuit breaker is always online.

4. Efficient Production Empowerment: Relying on the automated production line, the whole process from precision assembly to quality inspection is accurately controlled. The product has strong consistency, low defect rate, high cost performance and excellent quality. It is an ideal circuit protection choice for home, commercial and industrial scenarios.

1. The 2P leakage miniature circuit breaker adopts the leakage reset button function, which can directly judge the fault categories such as short circuit overload, leakage-triggered tripping, manual switching on and off, etc., helping users identify and lock the line fault points for quick maintenance, with the characteristics of safety, reliability and simplicity.

2. The 2P leakage miniature circuit breaker uses high-quality composite materials to improve product strength and high-temperature resistance. It adopts an independently developed new lever mechanism to enhance arc extinguishing capacity, extend product life and facilitate operation. The observation window uses red and green colors to distinguish the contact position.

3. Detail display: The miniature leakage circuit breaker is equipped with a test button, a visual window, clear parameters, smooth lines and stable installation.

To ensure the long-term and reliable operation of the 2P leakage miniature circuit breaker, it is recommended to carry out the following maintenance regularly:

1. Function Test

Press the test button every month to observe whether the leakage circuit breaker trips normally. If it does not act, it is necessary to cut off the power immediately to check the line or replace the equipment.

2. Appearance Inspection

Regularly check whether the shell of the leakage circuit breaker has cracks, deformation or ablation marks, whether the red and green window displays normally (red for disconnection, green for closing), and whether the parameter marks are clear.

3. Contact Maintenance

If contact oxidation or ablation is found, it should be gently polished with fine sandpaper by a professional electrician; in case of frequent tripping, it is necessary to check whether the line has continuous leakage or overload problems.

4. Environmental Cleaning

Regularly remove dust from the shell of the miniature leakage circuit breaker and the installation area to avoid affecting heat dissipation or reducing insulation performance due to dust accumulation. Especially in industrial environments with more dust, the cleaning frequency should be increased.

Q: What should be paid attention to when wiring the 2P leakage miniature circuit breaker?

A: When wiring, you need to pay attention to: 1. Incoming and outgoing line direction: Most products are marked with "upper in and lower out", that is, the live wire (L) and neutral wire (N) are connected from the upper part, and the lower part is connected to the load.

2. Neutral wire identification: The neutral terminal is usually marked with "N". It is strictly forbidden to reverse the live wire and neutral wire (which may cause the leakage protection to fail).

3. Grounding requirements: Ensure that the equipment shell is grounded (PE wire), but the 2P leakage miniature circuit breaker itself is not connected to the PE wire (the PE wire is directly connected to the equipment shell).

Q: What is the core function of the 2P leakage miniature circuit breaker?

A: 2P represents two poles, which can control the on-off of the live wire (L) and neutral wire (N) at the same time, and has three functions: overload protection, short circuit protection and leakage protection.

Leakage protection principle: By detecting the current difference (residual current) between the live wire and the neutral wire, when the leakage current exceeds the rated value (such as 30mA), it will trip quickly within 0.1 seconds to prevent electric shock or electrical fire.

Q: How to test the leakage protection of the leakage circuit breaker?

A: We will test the leakage protection of the miniature leakage circuit breaker by means of leakage tester detection, test button test, grounding resistance tester, parameter setting test, etc.

Q: What is the function of the leakage circuit breaker?

A: The leakage circuit breaker is mainly used to detect leakage in the circuit (current leakage) and quickly cut off the power supply when leakage occurs to prevent electric shock accidents or electrical fires. It can also provide overload and short circuit protection.

Q: What is your delivery time?

A: According to your order quantity, it is generally within 12 days after receiving the deposit.

Q: What are the payment terms?

A: We support T/T payment.

Q: What are the installation requirements for the leakage circuit breaker?

A: It should be installed by a professional electrician to ensure compliance with electrical specifications.

Install it in the distribution box to ensure correct wiring and correct connection of live wire, neutral wire and ground wire.

After installation, a test is required to ensure that the leakage protection function is normal.

Automated equipment can accurately control every link in the production process. Compared with traditional manual welding, it greatly improves the stability of product quality. At the same time, the automated process has greatly improved production efficiency. An advanced assembly robot can complete the assembly of hundreds of leakage circuit breakers per hour, which is several times the manual efficiency, effectively reducing production costs and ensuring that products can be launched on the market at a more competitive price.
