應用場景
廣泛用于建筑、工廠、礦山等領域的低壓配電系統(tǒng)，尤其適合需要對電動機或線路進行過載、短路保護的場合。其可靠性在頻繁啟停或復雜電網(wǎng)環(huán)境中表現(xiàn)突出，可替代傳統(tǒng)熔斷器實現(xiàn)更精準的保護。91521
Product Overview
The DW15-630 630/400A thermal-type AC220V universal circuit breaker is designed for AC power distribution networks, providing overload and short-circuit protection for electrical lines and equipment. With a rated current range of 400A to 630A and compatibility with AC220V, it suits industrial and commercial applications. Its compact structure and reliable operation ensure enhanced electrical safety. 169
Key Features
Featuring a thermal-magnetic trip mechanism, this breaker eliminates the need for undervoltage accessories. Its modular design integrates contacts and operating mechanisms on an insulated base, paired with an arc-extinguishing system. The drawer-type configuration (available in select models) simplifies maintenance, while its current-limiting capability makes it ideal for high short-circuit current environments. Manual and electric operation options are supported. 3612
Specifications
- Rated Current: 400A/630A (adjustable)
- Rated Voltage: AC220V
- Trip Type: Thermal-magnetic
- Mechanical Life: ≥2,000 cycles
- Arc Distance: ≤120mm (model-specific)
- Operating Conditions: -5℃ to +40℃, altitude ≤2,000m
The product meets general industrial requirements for motor protection or infrequent circuit switching. 2717
Applications
Ideal for low-voltage distribution systems in construction sites, factories, and mining facilities, particularly where motor or line protection against overload/short-circuit is critical. Its performance excels in dynamic grid environments with frequent start-stop cycles. 91521
