EB-VSM-12M-1250-25 12kV Handcart Type Permanent Magnet vacuum circuit breaker
Model: EB-VSM-12M-1250-25
The EB-VSM-12M-1250-25 handcart type vacuum circuit breaker is a high-reliability medium-voltage breaker designed for 12kV power distribution systems. It combines a Permanent Magnet operating mechanism with a high-performance vacuum interrupter, delivering stable switching performance, long mechanical life, and low maintenance requirements.
The breaker adopts a front-rear integrated layout of the permanent magnet mechanism and vacuum interrupter. Its withdrawable (draw-out) handcart design supports both motorized operation and manual operation, making it suitable for various switchgear configurations and user preferences.
The main conductive circuit uses a floor-standing structure. Vacuum interrupters and upper/lower terminals are encapsulated in APG-processed epoxy resin solid insulation poles, which provide:
Excellent dielectric strength
Strong mechanical durability
Dust-proof and moisture-resistant performance
Reliable insulation in high humidity and polluted environments
This model is equipped with an Eberry customized Russian-language control and indication panel, improving usability for Russian-speaking operators.
It is an ideal solution for projects in Uzbekistan, Kazakhstan, Kyrgyzstan, Tajikistan, and Russia, fully matching local operation habits and grid application needs.
The EB-VSM-12M-1250-25 is widely used in medium-voltage switchgear, substations, industrial plants, utilities, and infrastructure projects, offering safe, efficient, and long-term power system protection.
