The Tier 460 Terminal Block Motor/System Contactor Controller Restart Device will protect a motor, or an entire system, from power quality events. It runs onboard contactor restart in series with the load and the system. The contactor will disconnect the load at predetermined levels, and will reconnect the load at separate predetermined levels automatically.

 

Transient impulses can significantly impact your facility’s power quality, easily disrupting or damaging your process or equipment. While its important to protect against high-energy events, a more frequent, yet often overlooked power quality concern is the damage caused by a phase loss, a temporary voltage sag or a voltage swell condition. Disconnecting your sensitive loads during these longer duration power quality events is the easiest way to safeguard important equipment.

We will be happy to accommodate your needs.
