The SCHRACK circuit breakers MC and MO blend proven technology with state-of-the-art innovation. The switches are intelligent and perfectly match when combined. Both circuit breakers MC and MO sport modern communication functionalities. They offer more than just perfect protection from 0.16A to 6300A. The MC and MO switches mark a new generation of circuit breakers, which are sufficiently modular to allow each and every type of power distribution application. SCHRACK circuit breakers save money, they can be combined most flexibly and are suitable for integration in cross-connected system solutions.
The communication capabilities of the SCHRACK circuit breakers MC and MO open up a new world of possibilities for power distribution and automation. Relevant information can be obtained simultaneously. All results are available on site and the transfer of data to higher-level systems is easy as pie. The system becomes more transparent and the response times to critical events, such as overcurrent, phase imbalance or phase failure are minimised. Consequently, these switches help to take selective measures to prevent system failure and to schedule maintenance activities in time. They can increase plant and system availability and avoid costly production down-times.
The SCHRACK circuit breakers MC and MO are designed to achieve high selectivity. Setting up a selective network is easy with these switches.
Circuit breakers protect, connect and disconnect as required.
Circuit breakers always switch all three phases, which prevents motors from running on only two phases.
Once the problem has been resolved, a tripped circuit breaker can be simply re-activated.
Circuit breakers can be switched on and off remotely while indicating the state of the device.
These circuit breakers from 630A to 1600A are especially suitable for the Modul 2000TT models. The type tests were conducted with these circuit breakers.
The accessories can be easily retrofitted from the front. The installation point is the same for all sizes. The auxiliary contacts and the tripping indicator are contact elements from the SCHRACK control and signalling unit programme. They are available in screw and cage clamp technology. This shortens assembly time and reduces costs. Shunt or remote releases and undervoltage releases, also combinable with leading auxiliary switches for emergency stop function or load shedding circuits, offer elegant solutions for a wide range of applications. With the connection technology of the MC circuit-breaker series, you can react flexibly to any requirement of the system. Whether copper or aluminium cable, copper strip or copper rail, the MC has the right solution for every type of connection. An additional element increases the available touch protection level.
SCHRACK Technik offers a circuit-breaker range for all application needs, from among the small MC1 to our MC4 circuit-breaker, you will always find the right solution.
For all applications, there are different versions with thermobimetals or communication-capable digital electronics for various protection tasks: Both for AC or DC networks, from cable/line protection, including motor/generator protection to transformer protection, applications such as main, emergency main switches and coupling switches can be implemented with the switch-disconnectors up to 1600A.
