Operating Mechanism for MCB Miniature Circuit Breaker (1053023)
The operating mechanism is a mechanical system that drives the contact opening and closing. Its core functions are: ① Provide sufficient power to quickly close or open the contacts; ② Keep the contact pressure stable in the closed state; ③ Quickly trigger the opening in the event of a fault (cooperate with the release)
HAIPART utilizes a high-energy spring-loaded mechanism (charge time ≤ 8ms) combined with tungsten-copper alloy contact material to achieve a contact opening distance of ≥8mm at a 4.5kA breaking capacity for MCB products. A precision guide rail structure ensures contact pressure fluctuations of <5N (rated 100N). The product has passed the 10,000-cycle mechanical life test according to IEC 60947-2.
Why Choose the HAIPART Operating Mechanism?
✅
Mechanical optimization for millisecond-level breaking response
✅
Deep adaptation for smart power distribution scenarios
✅
Special protection requirements for new energy equipment
Applications
Suitable for smart power distribution terminals, industrial motor protection, new energy infrastructure, and other fields.
