ACB Is Air Circuit Breaker.
Masterpact, reliability
Merlin Gerin latest technology has produced a new concept for the Power Circuit Breaker. With all the advantages of modular construction in polyester enclosure, Masterpact offers performance that is more than just meeting international standards. Masterpact has a high thermal resistance to enable the workings of the so-called Total Discrimination. This is to ensure continuity of service due to a power source in the event of disruption (short circuit), Masterpact would "suspend" disconnection, before all the circuit breaker on the bottom side cut off (trip). Thus, if such interference can only occur at one point, then the circuit breaker in that area alone is disconnected.
Masterpact, without treatment
Without treatment, Masterpact can be operated as many as 10,000 times on the 1600A. If it happens 2 times a day trip, then Masterpact to serve the plant for 13.7 years without treatment. Only by changing the contact point and the arc chutenya, Masterpact to operate 20,000 times on the 1600A.

- Circuit breaker can be removed and inserted quickly without removing the power circuit, thus simplifying the treatment
- Can be conducted test / test trip unit
- Position the circuit breaker can be known ("connected", "test", "disconnected")
- By adding the buffer can be formed into a fixed type
Masterpact NT & NW
- Can be conducted test / test trip unit
- Position the circuit breaker can be known ("connected", "test", "disconnected")
- By adding the buffer can be formed into a fixed type

Optimal dimensions
- 1 frame size for Masterpact NT, power circuit breaker in the world's smallest
- 2 frame size for Masterpact NW
- 1 frame size for Masterpact NT, power circuit breaker in the world's smallest

Arc chute with a new design that is equipped with stainless steel filter
- Absorb the energy generated during disconnection so as to limit the stress that arises in the installation
- Filter and cool the gas produced and reduce splashing out particles that arise at short circuit.
Micrologic, intelligent trip unit
- The function of protection and an integrated measurement
- Display LCDdigital
- Protection system can be set using the dial or keypad (double setting)
- Choice of communication to integrate the circuit breaker into the supervision system, so that the function of protection, control and monitoring can be done remotely
Just desire to say your article is as amazing. The clarity on your put
ReplyDeleteup is simply great and i can assume you're a professional on this subject. Fine with your permission allow me to seize your feed to stay updated with forthcoming post. Thanks a million and please keep up the gratifying work.

I ωas curіous if you eѵer thоught of changing the ѕtructurе of your sitе?
ReplyDeleteIts very well written; I love what youve gοt to say.
But maybe уou could a little morе in the way of content so peoρle could connect with it bettеr.
Yοuve got an awful lοt of text for only having 1 or
2 pіctures. Maybe yоu could space
