Tier 460
The Tier 460 Disconnect 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.
