Intelligent Air Frame Circuit Breaker Unit

The Intelligent Air Frame Circuit Breaker Unit is a next‑generation protection device from Zhejiang Chenhai Electric. It features a microprocessor‑based trip unit with zone‑selective interlocking, reducing fault stress on downstream components. Rated currents from 800A to 6300A, with Ics=100% Icu. The LCD display shows real‑time current, voltage, power, and trip history. Optional Smart Energy Solutions integration allows remote monitoring and control via Ethernet. This breaker coordinates with Surge Protectors and Voltage Stabilizers to provide comprehensive electrical safety. For motor control centers, it pairs with Counters and Timing Control Devices to log start‑stop cycles and run hours. The drawout chassis includes position switches (connected, test, disconnected) for interlocking with Microcomputer Protection Devices. The electronic trip unit has eight selectable protection curves, making it suitable for transformers, generators, and long cables. Optional arc flash detection redu…
