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 startup 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 Pro Switch.
Installation of a contactor should be performed by a certified electrician as it involves custom connections.
The iVAC Contactor kit contains the following materials:
- Contactor 3Pole 42 Amp 120Vac control cCSAus approved
- 6′ control cable, 3 x 18G NEMA 5-15P UL/CSA approved
- 204 x 108 x 138 mm, IP65 CE enclosure box
- 2 x PG21 cable glands UL listed
- 1 x PG16 cable gland UL listed
Not Sure About Your Shop Dust Extraction Requirements?
Shop vacuums and dust collector HP ratings 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
