TeSys™ D IEC Style Instantaneous Control Relays
CAD32
These 600 V relays are approved for use around the world. TeSys D relays are usually
mounted on 35 mm DIN track, but can also be mounted directly to a panel. The contacts
have NEMA A600 and Q600 ratings, in addition to the standard IEC ratings, making
them suitable for use in most any control circuit. Low consumption versions are available
for use with low level DC control signals from a computer or a PLC. Adder decks can be
added to a basic five pole relay to make it up to an 11 pole relay. The serrated silver-
nickel contacts with wiping action provide excellent reliability in 12 or 24 V control
circuits. Special auxiliary contacts are available for switching low power down to 5 V at
10 mA. Timer and mechanical latch attachments are available.
