MS2 3PHASES VCB

It is used in air-insulated switchgear and SF6 ring main units, enabling applications such as fast circuit breaking, arc suppression, line selection, phase selection, and bypass. The MS‑series circuit breaker employs three single‑stable magnetic‑control mechanisms—one per phase—arranged vertically. All switching‑actuating components are axially symmetrical, and all moving parts undergo linear, vertical motion. The three operating mechanisms are housed within a single mechanism box and achieve synchronized operation and position indication of the auxiliary switches via a common synchronization shaft. The vertical arrangement of the magnetic‑control mechanism and the vacuum interrupter optimizes the interrupter's dimensions while significantly extending both its electrical and mechanical service life.

MS4 PILLAR TYPE 3-PHASES CIRCUIT BREAKER

Applicable to SF6‑filled switchgear and air‑insulated switchgear; the MS‑series circuit breakers employ three single‑stable magnetic‑control mechanisms, one per phase, arranged vertically. All switching‑actuating components are axially symmetrical, and all moving parts undergo linear, vertical motion. The three operating mechanisms are housed within a single mechanism enclosure and achieve synchronized operation and position indication of the auxiliary switches via a common synchronization shaft. The vertical arrangement of the circuit breaker's magnetic‑control mechanism with the vacuum arc‑extinguishing chamber optimizes the chamber's dimensions while significantly extending both its electrical and mechanical service life.

MS5 SHELL TYPE 3-PHASES CIRCUIT BREAKER

For air-insulated switchgear, the MS‑series circuit breakers employ three single‑stable magnetic actuation mechanisms—one per phase—arranged vertically. All switching‑action components are axially symmetrical, and all moving parts undergo linear, vertical motion. The three operating mechanisms are housed within a single mechanism enclosure and achieve synchronized operation and position indication of the auxiliary switches via a common synchronization shaft. The vertical arrangement of the circuit breaker's magnetic actuation mechanism with the vacuum arc‑extinguishing chamber optimizes the chamber's dimensions while significantly extending both its electrical and mechanical service life.
