A heavy duty 3 pole relay housed in an electrical box. Controlled from an iVAC Pro Switch S11520-A-NA or an iVAC Pro Switch Box SB-NA (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 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 kit includes the following materials:

• Contactor 3PPole 42 Amp 120Vac control cCSAus approved
• 6' control cable, 3 x 18G NEMA 5-15P UL/CSA approved
• 204 x 108 x 139 mm, IP65 CE enclosure box
• 2 x PG21 cable glands UL listed
• 1 x PG16 cable gland UL listed

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 for your workshop. iVAC recommends the use of the iVAC Contactor for:

• vacuums/dust collectors operating on 115Vac that are over 1HP
• vacuums/dust collectors over 2.0HP operating on 240Vac
• commercial/industrial units with a continuous rating of up to 10HP
