  Performance with a refined new design and functional beauty ADVANCED AND EVER ADVANCING MAGNETIC MOTOR STARTERSAND MAGNETIC CONTACTORS (Note)This mark indicates EC Directive Compliance.Products with the CE mark can be usedfor European destinations. series Mitsubishi Electric Corporation Nagoya Works is a factory certified for ISO14001 (standards for environmental management systems) and ISO9001(standards for quality assurance managememt systems)  Medium-and Large-Sized Models:S-N50~S-N800DC Electromagnet with ACOperation (Patented)Even Greater Contact Reliability MATCH WITH ELECTRONICCONTROL FOR FACTORY AUTOMATION If the magnetic relay coil is opened and closed near an electroniccircuit, malfunctioning of the electronic circuit could be inducedby a surge voltage. The UN-SA type surge absorber suppressesthe surge voltage when this coil is opened and closed. Inaddition to the general varistortype and the CR type that laysimportance on suppressing theinduction voltage when starting,the type with operating indicator(varistor type), and the varistortype with CR are available. One-touch surge absorber An easy-to-install terminal cover, which lays importance onfurther safety and is compatible with finger protection, has beenprepared. Finger Protection Compatible A new extinguishing structure, which eliminates the blow off ofhot gas (arc) to the front (direction to door of control panel)when the current is cutoff has been incorporated.In addition to improved safety, the freedom of panel design hasbeen increased allowing space to be saved. The arc blowoff direction has been changed tofurther improve safety and space conservation This is an auxiliary contact unit with low level contact, capable ofopening and closing the low voltage and minute current of theelectronic control circuit. It can be installed with one touch ontothe magnetic contactor or magnetic relay that opens and closesthe power of the motor, etc. The junction relay for opening andclosing the low voltage and minute current is not needed, sothis unit is suitable for opening and closing electronic inputcircuits in programmable logic controllers, etc. A compactmicroswitch is used for the low level contact, so the unit will notmalfunction due to fields andsurge voltages from the maincircuit current and coil of themagnetic contactor.A 1NO+1NC low level contactsand 1NO+1NC standard contactsare built-in, so the opening andclosing of 200VAC and 24VDCcan be handled with one unit. Auxiliary contact unit with low level contact S 2 types of inputs The long life no-contact output type (UN-SY21, SY31) andcontact output type (UN-SY22, SY32) are available. S One touch installation The UN-SY21, SY22, SY31 and SY32 types can be mounted withone touch onto the coil terminal. Post-installation work is easy. S Single standalone unit A single unit installation type(UN-SY11, SY12) is available forthe S-KR11 and S-N80 to N400magnetic contactor. Interface unit Coil power consumption is greatly low so MS-N Seriescontactors can be controlled by almost any type of relay, evensmall output relays of programmable controllers. Lower Power Consumption When switching a coil, the energy will be desipated within internalcircuit of electromagnetContact reliability has been greatly improved by the bifurcatedauxiliary moving contact Less Noise nor Surge from Coil The number of coil types has been cut by two-thirds and thereis no need to re-wire for different frequencies. The coil alsowithstands large voltage drops. Contactor Coils Have Ultra-Wide Range of Ratings DC excitation does not cause humming so operation is quiet.Internal circuit of the electromagnet Humming Completely Eliminated S-N510101010FrameN50/N65N80/N95N125~N220N300/N400N600/N800S-K1010305010Arc space(mm) Direct installation is possible on the following units:S-N series (Magnetic contactor) 65A frame or lessSR-N series (Magnetic relay) 4-pole, 5-pole and 8-poles types CCoilR ContactspringBifurcated movingcontactBifurcatedmovingcontactStationarycontact Arc space  TYPE REFERENCE LIST ........................................................................................................................................1 1.
