The 3SDH relay is designed for 100,000,000 operations at low levels. It is a four pole double throw Grid-space relay. The 0.150 inch pin spacing allows the user to insert the relay with no intermediate pin spreaders. There is adequate clearance for conductor to reach all pins.

Electrical Characteristics

• Contact Ratings —
  DC resistive — 2 amps at 28 volts,
  (DC 100,000 operations)
  DC inductive — 0.3 amp at 28 volts,
  (L/R not greater than 0.008)
  AC resistive — 0.5 amp at 115 volts,
  400 or 60 Hz (enclosure isolated from
  ground, or enclosure and movable
  contact at same potential)
  AC resistive — 0.125 amp at 115 volts
  (enclosure at line potential with respect
  to movable contact)
  Low-level — 50 μA at 50 mV
  Peak AC or DC
• Contact Resistance —
  0.050 ohms max.;
  0.150 ohms after life test
• Life — 100,000 operations at rated
  loads listed; 100,000,000 operations at
  low-level loads
