ASI is pleased to offer the Giovenzana International motor reversing switch, motor speed switch and motor start switch families. Giovenzana is a world leader in man machine interface products such as rotary cam switches, disconnect switches, pendant stations, push button switches and a variety of customer specific switches and control stations.

One Moment

The ASI rotary motor switch line is available in a AC motor reversing switch, with or without spring return, for reversing 3 phase motors up to 50 horsepower. For reversing a single phase motor you will find several options, including a single phase motor reversing switch for motors with a centrifugal cut out switch. Single phase motors from .5 horsepower to 10 horsepower can be controlled using the ASI motor star. When used as a drum switch in a reversing drum switch application the ASI motor switch can be used with single phase and 3 phase motors, depending on the model selected. The drum switch wiring diagram can be found on each of the product pages and in the drum switch data sheet.

The single phase and 3 phase motor starter switches and the motor reversing switches are available in rear panel mounting and fully enclosed in a NEMA 4X housing. A wide range of handles are available for use with the drum switches, motor start switches and the motor reversing switch including those capable of being locked with up to 3 padlocks.

The silver alloy contacts on the rotary cam motor reversing switch are double break and feature a unique design that maintains high pressure for increased contact reliability and long life. The housing of the motor reversing drum switch is made of a high impact thermoplastic that carries a UL94V0 flammability rating. The housings of the ac motor start and ac motor reversing switch is laser engraved to simplify wire positions and identification of the specific model.

Wiring to the single phase and 3 phase motor switches is made simple with captive metal parts that feature a screw clamp termination and to prevent shock hazard are fully insulated up to the 40 amp models.

All Giovenzana cam switches carry a cUL508 Listing, CE Mark, CCC, EAC, and other approvals, making them ideal for international applications. In addition, these compact designed rotary motor start and motor reversing switches carry AC21, AC22, AC23, and DC21 and DC22 ratings, making them suitable for just about any type of electrical application in an industrial environment.

In addition to the hundreds of models of standard rotary cam switches, including the rotary motor reversing switches and reversing drum switches, custom configurations of rotary cam switches and enclosed cam switches are available upon request.
