The following product line is being discontinued. A recommended replacement is shown at:

For DC control input applications: C Family SSRs

For AC control input applications: C Family SSRs




Single phase, up to 50, 75, 100 amp, din rail contactor

Features

  • For larger amperage applications
  • I²T fuse is built-in, replaceable, and it has a fuse failure LED
  • Automatic shutdown on over-temperature situations
  • Universal mounting bracket for din rail or bolt-on applications
  • Zero crossing activation -- low EMI, low noise to nearby electronics
  • Internal, oversized thyristors for high inrush capability
  • 1200 volt peak blocking voltage
  • UL recognized, CSA, CE
 50, 75, 100 amp solid state contactor

Part Number

DDA-6V50   up to 50A, 660V max, 4-28 VDC activated Buy
DDA-6V75   up to 75A, 660V max, 4-28 VDC activated Buy
DDA-6V100   up to 100A, 660V max, 4-28 VDC activated Buy

Please note: the above models are being phased out, due to the lack RoHS compliance. A suitable replacement is one of the following:

  • HDA-6V50E-HS1.0 for applications up to 40 amps (same physical size as a DDA-6V50), shown at: H Family SSRs
  • HDA-6V90E-HS1.0 for applications up to 60 amps (same physical size as a DDA-6V50), shown at: H Family SSRs
  • CZ2H-IDC2 for applications up to 100 amps (similar physical size as a DDA-6V75), shown at: C Family SSRs
  • A CZ2H-IDC2 will replace 2 of a DDA-xxxx. From a price perspective, one CZ2H-IDC2 costs less than 2 of DDA-xxx AND it is stronger, smaller, and repairable.
