note

Units are wired for 480 V unless 240 V is stated on order. The 480 V control circuit transformer is reconnectable for 240 V. For 240 V and 480 V, form FT is used. For other voltages, form SY74 must be used.

To get NEMA 12, add form N12 to unit.

Mag-Gard™ circuit breaker combination starter units through Size 4 are UL Listed for 22,000 AIR @ 600 V.

Footnotes

  1. Melting alloy overload relay included; thermal units must be ordered separately.
  2. Includes extra 1/2 space factor (additional space only).
