1. The matching cutter is equipped with a locking device. The hook plate, the self-locking plate, the torsion spring pull rod, the clamping plate and the limiting pin are connected with each other to form a clamping structure In opening and closing, the locking device automatically opens without human intervention and the locking device will act only when the rotating shaft is operated to ensure the reliability of the locking device;
2 .Static contacts should adopt L-shaped terminal conductive structure with good guiding performance. Material requirements: T2Y and above copper conductive system is more reliable, current capacity is enhanced, and temperature rise is low. It has passed the dynamic thermal test in Xigao Institute;
3. The circuit breaker adopts three-phase pillar structure, which has the characteristics of stable and reliable breaking performance, no combustion, danger, safety, maintenance-free, small volume, light weight and long service life;
4. The circuit breaker adopts totally enclosed structure, has good sealing performance, moisture-proof and frost-proof performance, and is especially suitable for severe cold or high temperature areas. The direct distance between the primary circuit and the box body is cut off by the umbrella skirt inside the three-phase pillar, so that the creepage distance is large.
5.We customize our products according to customer requirements.
