Safety Precautions

Please read the instruction manualbefore using the device.

G-199-3-C9173-A HQ1303 Printed in Japan (MDOC)New Publication, effective Mar. 2013.

Specifications are subject to change without notice.

MEDIUM VOLTAGESWITCHGEAR AND CONTROLGEAR

MP Series multi-relay● Combining the MP23 and wide-range

CT makes it easy to cope with the changes in load capacity by using only the CT ratio setting changes of the multi-relay (CT setting ranges are 60~600A and 200~2,000A).

● Display lights protrude from the panels to enhance visibility when viewing panels from side-on.

VPR-C Series VCBs● Comply with Restriction of Hazardous

Substances (RoHS).

● Long-life grease and non-lubricated bearing realize reduced maintenance.

Consideration for easy maintenance

● Through vertical location of the main busbar, maintenance from the back of panels is simplified, reducing maintenance work.

● The number of bolts for busbar connection has been reduced. This contributes to easier maintenance to check the bolt condition.

HIGH RELIABILITYMS is designed with the benefit of Mitsubishi’s vast medium voltage panels production experience of hundreds of thousands of panels over the last almost 60 years. 3D-Thermo Fluid Analysis of the switchgear structure has led to a heat-resistant design in which circuit breakers up to 3150 A are self-cooled (i.e. cooling fans not required).The reduced number of parts decreases the chance of failure.

EASY INSTALLATIONInstallation and testing duration are considerably reduced as the panel is tested and adjusted in the factory and then delivered as a complete unit.

SAFETYPartitions between compartments and an automatic shutter system (for withdrawable equipment primary junctions) completely isolate live parts.

Innovation

Since the 1950s, Mitsubishi Electric has been providing power distribution equipment and systems matched to the needs of the era. Now, inheriting the technologies and reliability forged from this manufacturing record of over half a century, the MS Series switchgear realizes the next evolutionary step forward.

ON/OFF of circuit breaker, REMOTE/LOCAL control mode selection, enable trip output contact, enable CB closing during a fault, setting of general purpose inputs and outputs, CB-ON delay timer

ON/OFF output of circuit breaker, TRIP output monitoring (using sequential logic), CPU condition, memory, AD converter, internal power supply, ratio check of analogue circuit

Standard equipping of MP Series digital multi-relays realizing even higher reliability

For the protective control device, MP Series digital multi-relays equipped with protection/control functions are adopted. Failsafe/Accident diagnosis functions are equipped, realizing an even high level of reliability. Furthermore, adding an optional transducer/transmission function and overall computerization of the power distribution equipment simplifies the interface with the central monitoring and control equipment.

High reliability

●The MP Series digital multi-relay centralizes measurements, protection and control functions into one unit, reducing wiring inside the panel by 50%.

●As a result of adopting the MP Series digital multi-relay and wide-range CT, it is not necessary to replace the CT in response to load changes. In addition, through adopting a composite CT*1 (optional), it is possible to achieve simplification of the ZCT high-voltage cable processing.

●MP Series digital multi-relays have five kinds of overcurrent protection properties equipped as standard, and it is not necessary to replace the relay.
