Phasing Hub is designed to phase inline or concentric shaft. The unit is bored to accommodate a given shaft diameter. When used inline the unit will phase 2 independent shafts. Also can be mounted onto a shaft and coupled to a sprocket or gear. The unit functions as a rigid shaft coupling. However, when adjusting ring is manually rotated, the assembly creates a 100:1 ratio.

Carlo Gavazzi has expanded their already comprehensive range of three-phase monitoring relays to include the DPB71 and the DPC Series. These are three phase devices which are ideal for protecting machinery and people in instances where three phase voltage is used, such as with industrial automation machinery, switchgear and elevators/escalators.

The DPB71 Series is constructed i... (read more)

A single ATC Diversified brand SLU Phase Monitoring Relay can be easily adjusted for the voltage, imbalance percentage and time delay requirements to protect against unbalanced voltages or single phasing regardless of any regenerative voltages. (read more)

Citel MSB series have been designed to protect single-phase circuits (16-amp current limit) against harmful lightning surges and electrical transients. Consists of a hybrid technology that combines a 3-element surge arrester gas tube and MOVs (metal-oxide varistors) to provide a high power-handling capability (20kA – 8/20 ms waveform) per phase.
