Area of application
Our master and EMERCENCY-STOP switches provide absolute
safety, even during maintenance and repair work. All-round
safety for people and machines.
With their high degree of protection of IP65, they can even with-
stand dust and water spray, providing unparalleled safety in the
building and industrial installations as well as the food and
chemical industry. Even with their enclosures open, they con-
form to protection class 2. IP20 is the minimum degree of protec-
tion.
■
Functions
The concept and mechanical construction of these switches are
designed for reliable function even under the harshest condi-
tions. In emergencies, every second counts, and our switches
allow immediate isolation.
Our enclosed master and EMERGENCY-STOP switches can be
locked with up to three padlocks and are available in two ergo-
nomically designed versions: from 16 A to 1000 A.
