Notes:
1. For case grounded loads and other ratings, consult the
factory.
2. For applications requiring other shock and vibration
levels, consult the factory.
3. For other ratings consult the factory.
4. Relay contacts which have switched high level currents
are no longer suitable for switching low level loads.
5. Contacts were placed in the position shown by placing
voltage with the polarity shown on the indicated coil
(reset). To switch contacts, a voltage of indicated
polarity must be applied to the other coil (Latch).
6. Contacts were placed in position shown by placing
voltage with the polarity indicated on the coil. To switch
contacts a voltage of the reverse polarity must be
applied to the coil.
