Top = Top Mounted Secondary Disconnects (TSD). Side = Side Mounted Secondary Disconnects (SSD). (Available on Envelope 1 only.) NOTE: N, U, M, S characters are for Envelope 1 only with top mounted secondary disconnects (TSD). When ordering codes A, B, C, D, Side Secondary Disconnects (SSD) are supplied as standard on Envelope 1. Codes N, U, M, S are not valid for Envelopes 2 and 3. Envelope 1 (Type N and H, 400A - 2000A). NOTE: DC Ratings; trip unit not included. DC Rated Circuit Breakers require external control devices (e.g., Type 37 or Type 76 DC Relays). NOTE: Side Secondary Disconnects are specifically intended for 5-High ("high density") equipment designs. With Side Mounted Disconnects (SSD), the following Aux. Switches are not valid (In Digit 12); Auxiliary Switch, 8NO+8NC (Power Rated) or Aux. Switch, 4NO/4NC (Power Rated) + 4NO/4NC (High Fidelity).

– 60 1 Switches (Digit 2 = M, S, C, D) do not have current Sensors or a trip unit –
