MCB
Prologue to Miniature Circuit Breakers (MCBs)
All wires should be supplanted with MCB for better security and control when they have carried out their responsibility before. In contrast to a wire, an MCB works as a programmed switch that opens in case of over the top current coursing through the circuit and once the circuit comes back to typical, it tends to be reclosed with no manual substitution. MCBs are utilized basically as an option in contrast to the wire switch in the vast majority of the circuits. A wide assortment of MCBs have been being used these days with breaking limit of 10KA to 16 KA

RCCB
What is an RCCB?
Leftover Current Circuit Breaker (RCCB) is a differential current detecting gadget used to ensure a low voltage circuit if there should arise an occurrence of a spillage shortcoming. It is in some cases otherwise called Residual Current Device (RCD). It contains a switch gadget that switches off (in a small amount of a second), at whatever point the present breaks out and doesn’t return through impartial
If there is even a few mill-ampere, it will detect and trip the power supply. The current that leaks out of the system is called residual current. The RCCBs are designed in such a way that, they are capable to continuously sense and compare the difference i.e. the residual current values between the live and neutral wires

ACB
Air Circuit Breaker (ACB)
Air Circuit Breaker (ACB) is an electrical insurance gadget utilized for impeding overcurrent security up to 15kV with an amperes rating of 800A to 10kA. It works in the air (where air-impact as a curve extinguishing medium) at environmental strain to ensure the associated electric circuits. ACB has supplanted by oil electrical switch since it is as yet a best decision to utilize an ACB because there is zero chance of oil fire like in oil switch
Sorts Air Circuit Breaker
There are four sorts of ACBs utilized in the control and insurance to keep up and stable activity of change gears and indoor medium voltage.
Plain Break Type Air Break Circuit Breaker or ACB
Attractive Blowout Type Air Break Circuit Breaker
Air Chute Air Break Circuit Breaker
Air Blast Circuit Breaker
ATS
Programmed Transfer Switches (rack ATS) give dependable, repetitive rack mount capacity to single-corded gear. The rack ATS has double info power lines providing capacity to the associated load. In the event that the essential force source gets inaccessible, the rack ATS will consistently source power from the optional source without hindering basic burdens. The Rack ATS has worked in arranging availability, which takes into account remote administration through Web, SNMP, or Telnet interfaces
They used to be called Robotic Transfer Switches. A three-stage switch will have sensors that sense every one of the three stages from the fundamental force source, and if anyone eliminates drops it will start an exchange arrangement. This is frequently first, shutting a transfer which starts firing up a generator, at that point when the generator power comes up to evaluated voltage, switches the three principle load stages over to the generator gracefully lines
