The 1220B operates on 240 volts and constant current of 5 amperes. The 1210B and 1220B operate from 0 to line voltage only. There is no reduction in allowable output current up to 1500 hertz.

Uncased models have the shaft extending from the base end. This shaft is fully adjustable and can be extended from either end for general utility mounting. Cased styles, which have a "CT" suffix, feature the protective screening over the coil assembly and a terminal box cover with knock‐outs to accept conduit.

Motor driven units are available in single, two, and three ganged assemblies; cased or uncased styles as identified by the prefix "M" in the type number. The synchronous motor is designed for operation on 120 volts, 50/60 hertz single phase lines and draws approximately 0.3 amperes. If a motor driven model is ordered, be sure to prefix the part number with the desired travel time from 0 to maximum of 5, 15, 30, or 60 seconds.
