Solid State Relays

Solid State Relay

Solid State Relays (SSR), designed by AMETEK, are used for loads up to 50 amps at 28 VDC, with no derating necessary for inductive and incandescent loads. The relay combines the functions of a power relay and an arc fault circuit breaker into a small module. The SSR is designed to trip on arcs, and over-current events without false tripping on normal inrush currents. Although the relays can handle loads up to 50 amps, the trip threshold can be programmed to a lower value.

Features and Benefits:

  • User adjustable trip curve and trip free reset
  • Discrete trip status output
  • Low off state leakage
  • Patented "fail-open" circuitry
  • No derating for inductive or incandescent loads
  • No wear out mechanism
  • Low voltage drop: efficiency >99%
  • Damage free interrupting capacity >1000A
