Compact construction and a 600 volt rating make these\nswitches suitable for a wide range of industrial and commercial uses. Typical\napplications include small machine tools, pumps, fans, conveyors and many\nother types of electrical machinery. They can also be used on non-motor loads\nsuch as resistance heating applications.. 30 amperes at 250 volts max, 26.4\namperes at 277 volts, 20 amperes at 600 volts max, 30 amperes resistive at 600\nvolts max.. Two speed manual switches may be used with separate winding three\nphase or single phase AC motors where overload protection is not required or\nis provided separately. Two switches are employed to give “ON-OFF” control in\neach speed.. Reversing manual switches provide a compact means of starting,\nstopping and reversing AC motors where overload protection is not required or\nis provided separately. They are suitable for use with three phase squirrel\ncage motors and for single phase motors which can be reversed by reconnecting\nmotor leads. Two switches are used, one to connect the motor forward rotation\nand one for reverse.. Class MMS, MRS, NEMA Type 1 surface mounting enclosures\nare sheet steel with a thermo-plastic wrap-around cover for convenience in\nwiring. The NEMA Type 1 enclosure is also available in an oversized version\nwhich allows more wiring space. A zinc alloy die casting is used for NEMA Type\n4 enclosures.. Red or green neon pilot light units are available for flush\nmounting plates, NEMA Type 1 enclosures, and NEMA Type 4 enclosures. Pilot\nlights may be either factory or field installed. (For switches that contain a\npilot light, a Red light is standard. For a Green pilot light add ”G” to the\nend of the catalog number.). Binding head screw type terminals are suitable\nfor 10 or smaller copper wire, and are accessible from the front. All\nterminals are clearly marked.. Open types without a pilot light fit standard\nsingle gang switch boxes, and can be used with any cover plate having a\nstandard toggle cutout. Single-unit flush mounting types, including those with\npilot lights, are suitable for wall mounting in a standard switch box or for\nmachine cavity mounting without a box.. Available with toggle handle or with\nremovable key type operator to discourage unauthorized operation.. A toggle\noperator extender is available for Class MMS, MRS, NEMA Type 1 surface mounted\nunits. The extender has a red vinyl button that provides a fast and easy\nmethod for locating and switching the device‘s toggle operator into the OFF\nposition. The Emergency Off Actuator is available in kit form only for field\ninstallation.. An optional handle guard on Class MMS, MRS, NEMA Type 1\nenclosed switches prevents accidental operation of the toggle operator and\nalso allows the toggle operator to be padlocked in either the “ON” or “OFF”\nposition. This handle guard is available in kit form for field installation on\nNEMA Type 1 surface and flush mounting enclosures. Standard NEMA Type 4\nmetallic enclosures include provisions for padlocking the device in the OFF\nposition.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eCountry Of Origin: United States\u003c\/li\u003e\n         \u003cli\u003eModel Number: MMSK01\u003c\/li\u003e\n         \u003cli\u003eItem Package Dimension: 4.\" L x 2.\" W x 2.\" H\u003c\/li\u003e\n         \u003cli\u003eItem Package Weight: 0.35 lb\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n","brand":"Siemens","offers":[{"title":"Default Title","offer_id":41604615241908,"sku":"B0094KVV6Y","price":199.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/products\/B0094KVV6Y.jpg?v=1656055199","url":"https:\/\/auspowers.com\/products\/siemens-mmsk01-fractional-hp-switch-single-and-3-phase-open-type-toggle-operator-type-standard-switch-feature","provider":"AusPower Australia","version":"1.0","type":"link"}
