Direct Opening Mechanism
1NC/1NO Contact (slow-action)
Conforms to EN60947-5-1 Direct Opening
(Only the NC contacts have a direct opening function.)
When contact welding occurs, the NC contacts are separated from
each other by pushing in the plunger.
Contact Form
Note: Terminal numbers are according to EN50013; contact symbols are according to IEC60947-5-1.
Lever
Improved safety of the lever-setting (Form lock configuration).
Many grooves are incised on the lever and the rotating shaft
that mesh with each other to prevent a slip between the lever
and the rotating shaft.
The lever can be set for positioning in steps of 9 degrees.
Built-in Switch
Has a direct opening mechanism separating
the contacts when the NC contacts are welded.
