MS2 3PHASES VCB

"Used for air-insulated switchgear (AIS) and SF6 ring main units (RMU), it can be applied for rapid breaking, arc suppression, phase selection, line selection, and bypassing. The MS series circuit breaker adopts three monostable magnetic actuators (one per phase, arranged vertically). All switching operation components are axially symmetrical, and all movable parts execute linear and vertical motion. The three operating mechanisms are built into a single mechanism enclosure and achieve synchronous operation and auxiliary switch position indication via a synchronization shaft. The benefit of the vertical arrangement between the magnetic actuator and the vacuum interrupter is that it optimizes the size of the vacuum interrupter while greatly increasing its electrical and mechanical 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 relative to 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 relative to the vacuum interrupter optimizes the interrupter's dimensions while significantly extending both its electrical and mechanical service life.
