High Breaking Frame Circuit Breaker ACB

The High Breaking Frame Circuit Breaker ACB from Zhejiang Chenhai Electric is engineered for demanding applications such as marine, mining, and heavy industry. It offers Icu up to 150kA at 690V and short‑time withstand current (Icw) equal to Icu for selective coordination. The drawout chassis includes a self‑locking mechanism that prevents accidental movement. The electronic trip unit provides adjustable protection parameters, including long‑time pickup and delay, short‑time pickup and delay, instantaneous, and ground fault. For environmental control, the breaker can be monitored by Temperature and Humidity Controller to ensure optimal operating conditions inside the panel. Integration with Timer Switches allows scheduled load shedding. The breaker works with Digital Pressure Gauges & Transmitters in hydraulic power systems where pressure and electrical protection must coordinate. Optional motor‑operated mechanism enables remote closing and tripping via SCADA. The auxiliary contact…
