SSM3 DIN Rail Mount SSRs

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.

Enhanced modular solution

  • Three-phase option and current rating of 25A.
  • Zero Voltage switching for resistive loads and Random switching for inductive loads.
  • UL and cUL approved including the general purpose and motor controller rating standards.
