Product Technical Feature
Circuit breaker using Three-phase pillar type fully enclosed structure, sealed performance is good, help to improve the moisture proof, prevent the condensation performance. Particularly applicable to cold or wet regions
The imported materials with good insulation performance, high temperature, UV-resistance and anti-aging.
Breaking performance is stable and reliable, no combustion and explosion danger.
Free maintenance, small volume, light weight, long service life.
Manual points brake or electric switching and remote control is viable.
Assort with intelligent controller to realize distribution automation. Or assort with reclosing controller, formed auto-recloser, sectionalizer.
Can be installed two phase or three phase current transformer for over-current or short-circuit protection.
Can provide current sampling signal for intelligent controller.
Can add measuring current transformer if customer required.
