IVAC C115-A-NA Contactor

The main limitation to controlling dust collectors is the start-up current surge, not the running current. In many cases the start-up current can be as much as four to five times the running current and last for several seconds. This initial surge can, over time, damage the contacts in the iVAC Dust Collection Switch Boxes. If you have a dust collector that requires power that exceeds the specifications of the either an iVAC Switch Box or the iVAC Pro Switch , the iVAC Contactor is the solution to this problem. The iVAC Contactor is basically a heavy duty 3-pole relay housed in an electrical box. Used inconjunction with an iVAC Switch Box or Pro Switch, the iVac Contactor has the ability to withstand surge (start-up) currents of up to 150 Amps and then maintain a running current of up to 40 Amps. It is also rated to operate at up to 230VAC single-phase or up to 600VAC three-phase, and has the ability to control dust collectors up to 10HP (depending on the configuration of the collector). The use of a iVAC Contactor is strongly recommended for any dust collectors operating on 115VAC that are over 1 HP, and for any dust collector over 1.5 HP operating on 240VAC. NOTE: Because the installation of the contactor usually requires a custom connection, the installation must be performed by a certified electrician. The installation guide can be seen on the iVAC web site. iVAC Contactor Kit: Contains a Contactor; Electrical Box; an Interconnect Cable to the iVAC Switch Box or iVAC Pro Switch S11515NA and S11520NA; and a set of required Hardware. All electrical materials are UL certified. Specifications Electrical Box - Measures 8" x 8" x 4". UL E109311. Contactor Rating - 240V AC , Surge Current 150 Amps, Running Current 40 Amps, 3 Pole, Control Voltage 115V AC, UL E249187. Control Cable - 115V AC - 6 ft. long, UL approved.

A heavy duty 3 pole relay housed in an electrical box. Controlled from an iVAC Switch Box or an iVAC Pro Switch S11515NA/S11520NA (not included). Withstands startup currents up to 150A and maintains running current up to 40 Amps. Contacts are rated at up to 600Vac, single or three phase. Warning! You must use a 115 volt Switch with the iVAC Contactor regardless of the operating voltage of your dust collector. iVAC Contactor – for larger workshops with heavy duty/industrial vacuums and dust collectors The iVAC Contactor allows you to connect a high powered dust collector or shop vacuum to your iVAC system. In larger workshops it’s common to see large dust collectors, sometimes up to 10 horsepower. These larger units can place heavy demands on your electrical circuits, and in many cases the start up current can be as much as four to five times the operating current and last for several seconds. This initial surge can over time damage the contacts in the iVAC Switch. The iVAC Contactor High Power Dust Collector Controller can withstand start-up currents of up to 150 Amps and then maintain a running current of up to 40 Amps. It’s also rated to operate at up to 600Vac in either single or three phase mode and can be used to control dust collectors up to 10HP and larger if the dust collector is operating on a higher voltage or 3 phase power. Installation of a contactor should be performed by a certified electrician as it involves custom connections. The iVAC Contactor High Power Dust Collector Controller kit contains the Contactor unit in a rigid electrical box, a connecting cable to an iVAC Pro Switch and required hardware. All electrical materials are UL certified. Not Sure About Your Shop Vacuum’s Requirements? Shop vacuums and dust collectors can be a bit confusing. To compel you to purchase, high horsepower figures are often stated on even the smallest machines, using the term “Peak Horsepower”. However, peak horsepower is the point at which a vacuum’s motor stalls, and does not represent the actual horsepower under typical operating conditions, or the unit’s vacuum pressure. Most residential shop vacuums that are sold over the counter are designed to operate on a typical 115Volt, 15 Amp circuit. That said, here are some rules of thumb for deciding whether or not you require an iVAC Contactor High Power Controller for your workshop. iVAC recommends the use of the iVAC Contactor for vacuums/dust collectors operating on 115Vac that are over 1HP, acuums/dust collectors over 2.0HP operating on 240Vac, or commercial/industrial units with a continuous rating of up to 10HP.
