iVac Contactor 7HP Capacity

undefined

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.
