Timers & Monitors
Industrial timing relays, voltage/current/phase monitors, and solid-state relays that protect and sequence equipment.
Anderson-Bolds supplies industrial timers and timing relays from ATC and SSAC, three-phase and voltage/current monitor relays from ATC Diversified, and solid-state relays from Carlo Gavazzi. Phase monitors protect three-phase motors from phase loss, reversal, and unbalance.

Timers & Monitors — questions buyers ask
What does a phase monitor relay protect against?
It protects three-phase equipment from phase loss, phase reversal, voltage unbalance, and over/under-voltage by opening a control contact before the fault damages the motor.
