⋆ NORMALLY CLOSED CONTACTS: Listed relays are supplied with all contacts normally open. These contacts can be readily converted to normally closed in the field.
‡ OVERLAP CONTACTS: Overlap contacts (normally open contact closes before the normally closed contact opens) can be supplied. See for information on kits for field installation of overlap contact cartridges.

⋆ NORMALLY CLOSED CONTACTS: Listed relays are supplied with all contacts normally open. These contacts can be readily converted to normally closed in the field. Relays having combinations of normally open and normally closed contacts can be supplied.
‡ OVERLAP CONTACTS: Overlap contacts (normally open contact closes before the normally closed contact opens) can be supplied. See Accessories for information on kits for field installation of overlap contact cartridges.
§ BIFURCATED CONTACTS: To order a relay with bifurcated contacts, add the letter “B” after the letter “T” in the Cat. No. Example: Cat. No. 700-NT200A1 becomes Cat. No. 700-NTB200A1.
