The KDCM-40.5/630-20-X series 33KV Medium Voltage Circuit Breaker Operating Mechanism is a critical component in medium-voltage power distribution system, as a circuit breaker actuator which governs the opening and closing of the main circuit breaker. Manufactured by Cotenele, a professional China supplier, this operation mechanism utilizes a unique dual-spring system:a tension spring for closing and a compression spring for opening,This dual-spring system can ensure reliable operation of circuit breaker.

Cotenele International Trade (Wenzhou) Co., Ltd., a leading Chinese manufacturer, produces the 22kV Vacuum Circuit Breaker with Load Break Switch, a core switching element in ring main units (RMUs), typically used to achieve safe and reliable power control in medium-voltage distribution networks. Its three-position load break switch integrates visual isolation and grounding functions, primarily used to interrupt load current under normal operating conditions. In modern power distribution systems covering voltage levels from 6kV to 40.5kV, this load break switch is a crucial core component of ring main unit switchgear.

The KDCM-24D/630-20 series 22KV Medium Voltage Switchgear Electrical Mechanism from Cotenele International Trade (Wenzhou) Co., Ltd combines tension and compression springs to ensure reliable operation, with a mechanical endurance exceeding 10,000 operations. Supporting both manual and electric operation, the mechanism features anti‑misoperation design and complies with GB 1984 - 2014 (high-voltage AC circuit breakers) and GB/T 1985‑2023 (high-voltage AC disconnectors) standards.
