DiversiTech Contactor 2P 30A 120V TMX230B2

The DiversiTech TMX230B2 is a two pole contactor rated 30 amps with a 120 volt coil.

Interchangeability between contactor series is a practical question that arises whenever a specific part is unavailable and a substitute is proposed.

The specifications that must match are the coil voltage, the pole count, the current rating including locked rotor capability, and the physical mounting and dimensions. Terminal type and arrangement must also suit the existing wiring, since a contactor with different terminal positions may require the harness to be reworked.

What need not match is the manufacturer. Definite purpose contactors are broadly standardised in their mounting patterns and dimensions, which is why aftermarket replacements are practical.

What is frequently overlooked is the current rating basis. Contactors may be rated in different ways by different manufacturers, and a nominal amp figure alone is insufficient. Comparing full load and locked rotor ratings, rather than the headline number, avoids fitting a contactor that is nominally equivalent but functionally undersized.

Where any doubt exists, selecting against the equipment nameplate rather than against the outgoing part is the more reliable method.

At 30 amps with a 120 volt coil this suits line voltage controlled equipment in light commercial HVAC and refrigeration.
