DiversiTech Definite Purpose Contactor C350C

The DiversiTech C350C is a three pole definite purpose contactor rated 50 amps with a 208/240 volt coil.

Conductor sizing at a contactor of this rating deserves verification rather than assumption. A 50 amp contactor implies conductors sized for the actual load, and where a contactor is being replaced with a higher rated unit because the original failed repeatedly, the conductors and the branch circuit protection do not automatically become adequate for the larger rating.

The correct sequence is to establish the load from the equipment nameplate, size the conductors and overcurrent protection to the code for that load, and select a contactor rated for it. Fitting a larger contactor to solve a failure problem, without establishing why the original failed, frequently addresses nothing: if the cause was short cycling, poor terminations, or an equipment fault drawing excessive current, a larger contactor simply fails more slowly.

Terminal capacity is also worth checking. A contactor's terminals accept conductors within a stated range, and a conductor too large for the terminal cannot be terminated properly, which reintroduces the loose connection problem the larger conductor was meant to avoid.

At 50 amps in three poles this contactor suits substantial commercial equipment. Applications include commercial air conditioning, refrigeration, and process cooling.
