Heavy Duty Duplex Controllers

Combination Circuit Breaker · Class 84

Duplex Heavy Duty Controllers are designed to perform duplexing and alternation.

The duplexing function provides capacity for system peaking or above normal demand without having the full motor capacity spinning at all times. It also provides standby capacity for use when one of the motors or pumps is disabled.

The alternation function reverses the lead and lag mode for the two motors in a duplex system. Upon alternation, the first motors becomes the lag motor and the second motor assumes the lead function. The alternation function equalizes wear on the two machines and extends the life of seals and bearings.
