Product Description

1. PRODUCT OVERVIEW
FRZW20 is an improved product of ordinary pole-mounted vacuum circuit breakers. It adopts a mature box-type sealing structure with excellent sealing performance, making it unaffected by external environmental factors. It is a maintenance-free product. Its spring operating mechanism uses direct chain main drive and multi-level trip system, ensuring high reliability of operation. It is a high-end product among pole-mounted circuit breakers. In addition to its superior sealing performance compared to ordinary vacuum circuit breakers, FRZW20 also features overcurrent protection, trip counting, mechanism spring energy storage indication, and is equipped with an aviation socket for secondary electrical connection, facilitating integration with intelligent controllers and other functions.

2. PRODUCT FEATURE
2.1 Ideal equipment for urban and rural power grid transformation: Can be paired with a controller to achieve remote control, remote measurement, remote signaling, and remote adjustment functions;
2.2 Flexible and convenient operation: This product is equipped with electric energy storage, electric switching, as well as manual energy storage and manual switching, and can be operated remotely at close or long distances;
2.3 Superior breaking performance: Breaking short-circuit current of 20KA up to 30 times;
2.4 Low operating power and high reliability: The newly designed small electric spring mechanism reduces the number of components and operating power (approximately 30W) to the lowest level;
2.5 Maintenance-free characteristics: The main circuit, secondary components, and operating mechanism of the circuit breaker are all sealed in a few gases (zero gauge pressure), unaffected by external environmental factors;
2.6 Reliable sealing performance: Adopt mature sealing structure technology with reliable sealing performance;
2.7 Unique incoming and outgoing line method: Using silicone rubber sleeves to ensure sufficient insulation distance between terminal connections and excellent external insulation characteristics;
2.8 Safe to use: An explosion-proof device is installed on the top of the enclosure, even in the event of an internal malfunction, there will be no leakage of high-temperature gas or splashing materials.
