Mechanically held

(1) Example: 8903 LXG 20 V02 P1.

(2) For electrically held enclosed devices, the first pilot light is wired in parallel with the coil. Operating interlocks are required for all additional pilot lights.

Mechanically held devices require operating interlocks for all pilot lights.

(3) Do not use suffix "X" for any interlock which is wired in series with pilot light, but do specify how pilot light and interlock are to be wired into the circuit.

(4) Available for 24 V, 120 V, 240 V and 277 V applications only.

(5) Electrically held (Type L) multipole contactors cannot add interlocks. Additional poles can be used for the same function, however. Mechanically held (Type LX)

contactors provide one double-throw auxiliary (or status) contact as standard.
