rcm panel confusion

[Tally Ho]

so i know for the 2t22 you need an rc5 or rc5w motor starter, and for the 3t22 you need a rc6 motor starter. and i was wondering, is there a such thing as a rc6w motor starter? and also if you have a single phase 2t22 you would use a rc5wb motor starter and with the three phase 2t22 you would use a rc5wa motor starter? same thing with the 3t22 or is there only the rc6 motor starter. thanks.

Your thoughts are mostly correct. The RC5(W)A and RC6A are for 3 phase and the "B" variant is for single phase. The W just meant that the motor starter is in a weatherproof cabinet. The non-W variant isn't weatherproof and usually installed inside a building.

The RC6 (both A and B) were already in a weatherproof cabinet and didn't need the W variant. The RC6 has the motor starter for the siren and the flasher to control the solenoid timing and came in the same size cabinet used for Thunderbolt RCMs.

Found this on a thread. Helps you for getting the right controller if you're willing to own more Federal sirens :
