I have used SSR blocks, 25-40 A @ 120-240V with 5 V turn on control with several multi Audio Amplifier rack installations with any difficulty. Easily a 40-50 A turn on surge or higher peak. RF filtering on the control lines is a must for transmitter use. Failure mode is ON so there should be a backup manual switch just in case, altho have never actually seen one short out in rated service. I have used some of the smaller SSR relays to interface between a lower voltage or DC PTT or Antenna Relay switch line when using 120 volt Dow Keys. Works well.
