Ready to use “Plug and play”

  • Modular design of IP 20 housing and built-in heat sink for optimized operating conditions.
  • Easy mounting on standard 35 mm/1.378 in. DIN rail with a secure mounting latch.

Compact design

  • Requires less panel space due to slim width and thus reduces the size of your enclosures.
  • Optimized modular design available in various sizes (22.5 and 45 mm width) with load output current of 20, 30, 45, and 55 A.
  • Wide choice of relays with single-phase options and current ratings from 20 A to 55 A.
  • Zero Voltage switching for resistive loads.
  • UL and cUL approved including the general purpose and motor controller rating standards.

SSM solid state relays are compact designed relays with greater power density. The modular IP 20 housing design and built-in heat sink offers optimized operating solutions.

The SSM relay range comprises:

  • SSM1: Single phase SSR relays with 20, 30, 45 and 55 A ratings

SSM1 relays, 22.5 mm/0.886 in. (20 A, 30 A) width and 45 mm/1.771 in. (45 A, 55 A) width

  • Lugs for panel mounting
  • Built-in heat sink for heat dissipation
  • Control input connection terminals
  • Control input voltage LED indicator in green
  • Bracket for mounting on 35 mm/1.378 in. DIN rail
  • Load output connection terminals
