Safety-Oriented Lever Setting
Grooves which engage the lever every 90° are cut in the
operation indicator disk to prevent the lever from slipping
against the rotary shaft.
Reset Head
The direction of the reset head can be adjusted to any of
the four directions.
Built-in Switch
Has a positive opening mechanism separating the con-
tacts when the contacts are welded.
Cover
The cover, with a hinge on its lower part, can be opened by
removing the screw of the cover, which ensures ease of
maintenance and wiring.
