
HFD = 200 and 225 amperes, HLD = 600 amperes, HMD = 800 amperes for 240/120 Vac single-phase, 3-wire and 208Y/120 Vac 3-phase, 4-wire systems only.

The Contactor-Based Transfer Switch is currently available in 100, 200, 320, 400 and 600 amperes only. Contact the factory for availability on the 800,
1000 and 1200 ampere switch.

For closed transition contactor, CTC8C3, consult factory.

For Bypass Isolation contactor, BICIC3, consult factory.

4-pole 600 ampere will use an NB breaker.
Note: MCB = Molded Case Breaker, MCS = Molded Case Switch.
