Vacuum circuit breaker is the most commonly used type of high-voltage circuit breaker, mainly divided into two kinds of indoor and outdoor. We mainly focus on indoor vacuum circuit breakers. (Indoor circuit breakers: High-voltage circuit breakers that do not have the performance of protection against wind, rain, snow, ice and dense frost, etc. and are suitable for installation and use inside buildings.) The vacuum circuit breaker is named after its interrupting medium and the insulating medium of the contact gap after interrupting is high vacuum; it has the advantages of small size, light weight, suitable for frequent operation and interrupting without maintenance, and is more popularly used in the 3kV-40.5kV distribution network. The components of vacuum circuit breaker are vacuum interrupter, electromagnetic or spring-operated mechanism, bracket and other parts. Vacuum interrupter is the core component of vacuum circuit breaker, its main role is, through the excellent insulation of the vacuum inside the tube to make the medium and high voltage circuit cut off the power can quickly extinguish the arc and suppress the current to avoid accidents and accidents.

VSG indoor high voltage vacuum circuit breaker  is used for 24KV power system indoor switching equipment, as power grid equipment, industrial and mining enterprises power design protection and control unit VSG-24C type Side installation Indoor high voltage vacuum circuit breaker used spring to storage energy. The operating mechanism can be operated by two ways, by manual and electromotive operation, The characteristics is according with GB1984-2003 High Voltage AC Circuit Breaker, JB3855-1996 3.6-4.5KV Indoor AC High Voltage AC Circuit Breaker and IEC standard 62271-100:200162271-100:2001 High Voltage AC Circuit Breaker

SOLH CRBU2 ultra-thin free-mount vane rotary actuator is fully interchangeable with equivalent SMC models, available in bore sizes 10/15/20/30/40. Integrated cylindrical body enables bracket-free multi-directional fixing, 12% lighter than CRB2 series, perfect for concealed installation inside compact integrated machinery. Direct vane drive eliminates gear backlash with ultra-high angular repeatability of ±0.01°. Two vane variants: S single vane for max 270° swing, D double vane delivering double torque with limited 90°/100° rotation. Dual piping layouts are offered: standard side ports and suffix-E central axial ports. Optional suffix-W angle adjuster realizes infinitely adjustable stroke from 0 to 240°, and built-in magnetic rings support M9BW reed switches for PLC limit feedback. Low-friction composite sealing ensures oil-free operation with over 5 million service cycles. Widely applied to light-load high-frequency precision rotation tasks including 3C miniature jig turnover, vision camera positioning, screw tightening mechanisms and small-angle packaging switching. Compared with base-mounted CRB2 rotary cylinders, CRBU2 requires no mounting brackets and maximizes space efficiency, ideal for robot end effectors and narrow internal equipment layouts.
