Size 0 through 4
The following features are characteristics
of Sizes 0 through 4.
Gravity Dropout — For added reliability,
the gravity dropout of the armature and
contacts is assisted by stainless steel
springs which help provide quick, precise
opening of the contacts. Also provides
straight through wiring.
45 Degree, Wedge Action — The 45
degree, wedge action contacts reduce
tracking and provide faster arc quench-
ing. The resulting self cleaning and
reduced contact bounce mean cooler
operation and longer life for the large
silver cadmium oxide contacts.
Terminal Design — Control terminals
are self rising pressure type.
Auxiliary Contacts — Front mounted as
well as side mounted auxiliary contacts
are available. A maximum of four can be
mounted on sizes 0 through 1
