POLE-MOUNTED SWITCH

Magnetic Control Pole-Mounted Circuit Breaker

The HZW32-12/M630 series magnetic control pole-mounted circuit breaker is an outdoor distribution device with a rated voltage of 12kV and a three-phase AC frequency of 50Hz. It is primarily used to close load current and break overload and short-circuit currents in power systems. This circuit breaker can serve as a sectionalizing switch on 12kV distribution main lines, branch lines, and ring networks in urban grids, as well as an incoming line switch for rural grids, industrial and mining enterprises, residential areas, and construction sites.

Magnetic Control Pole-Mounted Circuit Breaker
Features
Efficient Vertical Movement: The mechanism features a completely vertical movement for high efficiency.
Reduced Moving Parts: Only includes a moving iron core, connecting rod, and moving contact, resulting in low mass and fast movement speed.
Simplified Mechanism: Due to the high hardness of the magnetic material, the moving and static iron cores can directly collide, eliminating the need for contact buffering, simplifying the mechanism and facilitating adjustment of overtravel and contact pressure.
High Environmental Stability: The magnetic material has a high demagnetization temperature, providing strong environmental adaptability and high stability.
