YHCW1 SERIES INTELLIGENT AIR CIRCUIT BREAKER

YHCW1 Series Intelligent Air Circuit Breaker (ACB) is applicable to AC 50 Hz distribution networks with a rated insulation voltage up to 660V (690V) and rated currents ranging from 630A to 6300A. It is designed to distribute electrical energy and protect power lines and equipment against overloads, undervoltage, short circuits, and single-phase earth faults.
Featuring intelligent protection functions and precise selective coordination, the circuit breaker significantly enhances power supply reliability while minimizing unnecessary outages. Furthermore, it is equipped with an open communication interface supporting the "Four-Remote" functions (Remote Metering, Remote Signaling, Remote Control, and Remote Adjustment), thereby meeting the requirements of control centers and industrial automation systems.

Reclosing residual current protective circuit breaker

The YHM5EL series circuit breaker is a multifunctional, compact, and intelligent device designed for IoT‑enabled distribution networks. It is suitable for three‑phase four‑wire power supply and consumption systems with a directly grounded neutral point, capable of comprehensively measuring electrical parameters such as power, energy, power factor, and harmonics. Equipped with protection functions including overload, short circuit, phase loss, overvoltage, undervoltage, and residual current tripping, it safeguards circuits and electrical equipment from damage while also providing protection against ground faults and indirect contact hazards.

HIGH-VOLTAGE MOLDED CASE CIRCUIT BREAKER

Model YHM6 High-Voltage Molded Case Circuit Breaker
It is applied in high-voltage power grid circuits with rated operating voltages of 800V, 1000V, 1140V and rated operating current ranging from 63A to 800A. Equipped with overload and instantaneous short-circuit protection functions, it is used for power distribution and protects cables and power equipment against damages caused by overload and short-circuit faults.
