GENERAL:
These devices are open or enclosed type magnetically operated lighting
& heating contactors.
Ratings - They are rated as follows. All tungsten and ballast ratings
are 1 phase, 2-pole and 3-phase, 3-pole. Resistive ratings are per pole,
including 1 pole, 1 phase; 2-poles, 1 phase; 3-poles, 3 phase. (Wye or
inside the delta, normally open).
All resistive ratings were tested for 250,000 operations to cover
resistance heating applications:
