Industrial Motor Starter Switch

The Killark FXSX52 is a single-gang control station rated for 20 A AC service. It carries Class I Division 1 and 2 Group C and D hazardous-location approvals alongside Class II Division 1 and 2 Group E, F, G and Class III Division 1 and 2 ratings. A built-in pilot light provides local status indication for motor circuits in demanding environments.

Sustained Load Behaviour

The two-pole switch handles continuous duty at the full 20 A rating across single-phase 120 V and 240 V supplies delivering 2 hp, and three-phase 480 V and 600 V supplies delivering 3 hp. One thermal unit is required for overload protection, and the enclosure dimensions of 3.688 in by 5.344 in by 6.813 in house the operator handle without additional IP sealing.

Replacement And Upgrade Context

This station replaces legacy single-gang motor starters that lack hazardous-location certification or an integrated pilot light. The jump is worthwhile when the application demands Division-rated construction for Class I, II and III atmospheres and a compact footprint that matches the listed enclosure size. It does not suit installations needing multi-gang configurations or higher current ratings.

Questions about this item

How much heat does the 20 A motor starter generate when running continuously?

The unit carries a 20 A rating and is built for hazardous-location enclosures, so heat dissipation depends on the conduit and ambient conditions at the installation site.

What conduit size must I already have to mount this 3/4 in control station?

It requires a 3/4 inch conduit entry and a single-gang opening for the operator handle and pilot light.

Will the 2 hp single-phase rating at 120 V AC work with my existing 120 V motor?

Yes, the station is rated for 2 hp at 120 V AC single-phase and also at 240 V AC single-phase, matching common legacy motor voltages.
