HYW3 Intelligent Universal Circuit Breaker

Product Overview

The HYW3 series intelligent universal circuit breaker (hereinafter referred to as the "circuit breaker") is suitable for AC 50/60Hz power systems with rated operational voltages up to 690V and rated currents up to 6300A. It is primarily used for power distribution, feeder protection, and generator protection in electrical networks, safeguarding lines and equipment from overloads, undervoltage, overvoltage, current/voltage imbalance, short circuits, and grounding faults. The circuit breaker can also directly protect motors and generators against overloads, undervoltage, and short circuits. Its core component employs an intelligent controller, enabling precise selective protection to minimize unnecessary power outages and enhance power supply reliability, continuity, and safety. It may also include an open communication interface to achieve "Four Remote" functions (remote measurement, signaling, control, and adjustment) for integration with control centers and automation systems.
