The Tier 460 Line Cord Receptacle Motor Surge Protection Contactor Restart Device will protect a motor, or an entire system, from power quality events. It runs an onboard surge protection device in series to an onboard contactor restart. The contactor will disconnect the load at predetermined levels, and will reconnect the load at separate predetermined levels automatically. The onboard SPD remains online while the load is disconnected.

This twofold level of protection greatly improves system defenses from power disruption damage.

 

The 460 SPD family is the ideal solution for protecting industrial systems, motors, and equipment from the damaging effects of transients, phase loss, voltage sags and swells.

The 460 is available with a contactor restart option or a shunt -trip controller

 

The 460 Motor Surge Protection Contactor Restart features the industry's most advanced metal oxide varistor (MOV) technology.

Its thermally protective, and arc extinguishing, design has a significant advantage when subjected to abnormal over-voltage and high fault current.

 

The multiple MOV technology allows for the continuation of protection even after a module failure (indicated by our dual color LEDs), giving critical time, under reduced protection, for a repair or replacement (This is covered by our 10 year warranty).

 

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.
