RiMS – Advanced MCC system with withdrawable modules


Nabla Slavonija is distributor and integrator of RiMS system, advanced MCC system with withdrawable modules based on Rittal Ri4Power system and IDS’s e-con s.i. innovative system for MCC technology.

Compared to the classic solution with a fixed installation of the equipment, or the solution with plug-in modules, modules with fully withdrawable technology proved to be the best solution for Motor Control Center (MCC-s).
Field of application of systems with withdrawable modules is in critical power systems, in which the withdrawable modules, in case of failure, can be quickly, easily and safely replaced.

RiMS-modularni-dizajnApplication examples for MCC system with withdrawable modules are:
- industry (due to the high cost of production downtime)
- municipal systems (e.g. water treatment plants)
- banks or data centers (due to the high cost of downtime)
- hospitals
- process oriented production plants (e.g. chemical, oil and gas, cement industries and power plants … )



• modular concept ensures high availability and reduced time for repairs
• modules can be replaced under operating conditions
• basic module height of 75 mm ensures high density of installation and save space
• withdrawable modules can be equipped with low voltage equipment of all renowned manufacturers

• RiMS system is arc-free due to:
– the drawer-units are constructed in such a way, that the contacting device, the vertical bus-section and the power-plug form up together an hermetic encapsulation
– the vertical-bus-section of each cubicle are completely insulated, from phase to phase as well as from phase to earth to reduce the risk of an internal arc-fault
– each power-contact is insulated against its neighbor-contact and against earth, that in case of an overload, ionized gases cannot shortcircuit two phases or a phase against earth
– isolated contacts and bus avoids the short circuit caused by a variety of contaminants in the area
• this system has been tested and certified by international testing laboratories

• the contacting-device of the drawer-unit is constructed in such a way that under no circumstances the contacting-pressure will be reduced or even lost during a short circuit.
• moving the drawer-unit to operating- or test-position doesn’t influence the protection-degree of the switchboard.
• moving the drawer-unit to operate-position is possible while the whole power-cabling stays fixed (Power-cabling should not be moved to avoid breaking wires)
• the contacting-device is of self-cleaning type when pushing or turning it to operating-position, so that it will be maintenance free
• each contacting device is individually tested and labeled with a serial number
• contact elem. is controlled by the detachable handle, so on/off operation can be done only by authorized personnel
• extraction of module is prevented if the module is in operating or test position
• it is possible to encode each module with a unique code

• Nabla Slavonija has all relevant certificates required for installation and use of this system
