Product Description

HKL-12 Indoor HV Vacuum Circuit Breaker

Product Description

Overview
This product integrates vacuum circuit breaker, isolating switch, grounding switch current transformer, and sensor; the product is designed as a side-mounted product, which conforms to the trend of miniaturization, and apply to the cabinet size 520x1000x2000mm (WxDxH). Also can be used in high-voltage fixed switchgear with model XGN2,XGN66, etc., The normal switchgear's isolation switches, vacuum circuit breakers, grounding switches, current transformers, sensors, and mechanical interlocks should be installed and debugged separately, The process is complicated, labor-consuming. While this series products are equipped with a multi-functional  vacuum circuit breaker, and this circuit breaker has an isolation position, a circuit breaker position, and a grounding position, so it is more integrated and systematic, and the installation is simple, fast, convenient and reliable.

Using conditions
Ambient air temperature: -25°C ~+40°C;
Relative humidity: Daily average≤95%; Monthly average≤90%
Altitude:≤ 1000M;
No flammable, explosive, strong chemical corrosive and violent vibration
