Unique Design, Practical Performance, and Competitive Price 4p Molded Case Circuit Breaker 100A

4P means that the circuit breaker has four protection poles (3 phases + neutral line), which is used in three - phase four - wire systems (such as 380V / 400V systems). It can disconnect the three - phase power supply and the neutral line at the same time, and is suitable for scenarios with strict requirements for neutral line protection (such as preventing electric leakage and voltage imbalance).

Before the products leave the factory, we will conduct comprehensive and strict tests, including electrical performance testing, mechanical performance testing, appearance inspection, temperature rise test, etc., to ensure that the product quality meets the standards.

Fixed type: Install directly in the power distribution cabinet, and sufficient heat dissipation space should be reserved. Plug - in / drawout type: It is convenient for quick replacement, and it is necessary to ensure that the guide rail or base is compatible. Wiring must comply with specifications (such as matching cross - sectional area of copper bars, tightening torque).

We start with raw material inspection to strictly control the quality of raw materials; implement refined quality control in the production process; conduct multiple rounds of quality inspection and testing after the finished products are completed; and provide perfect after - sales service to comprehensively ensure product quality.

We use carton packaging, cardboard box packaging, and wooden box packaging (all in line with international export standards) to ensure that the products are not damaged during transportation.
