Double Break Mechanism
Double Break Mechanism
ACE2 MCCBs have double break mechanism, which means
Electric characteristics as per IEC 60947-2 Rated current (A) In
n No Load line bias i.e. either terminal can be used for incoming/outgoing termination.
Rated insulation voltage (V) Ui
n Load Line interchangeability enhances ease of termination & that too without reduction in performance.
Rated impulse withstand voltage (kV) Uimp Rated operational voltage (V) Ue

Current limiting Unique rotating double break technique ensures current limiting & very fast clearance of short circuit current.
Current Limiting
n Enhances breaking capacity of the breaker. n Low let thru energy, resulting in lower thermal stresses
Prospective current peak
n Reduces electro-dynamic & thermal stresses on the electrical distribution network. n Low temperature rise & hence lengthen life of associated equipments & cables. n Safety to the plant & operating personal.
Actual current peak
n Increases life of cables & installation.
