All safety switches can be protected against inadvertent switching on by our integrated locking facility for up to three padlocks in the OFF position.
To prevent manipulations, the enclosure covers cannot be opened in
the locked position without destroying the enclosure itself.
switches feature full AC-3 motor switching capacities and isolating
properties according to EN 60947-4-1 with compulsory opening of the main
current contacts; optional EMERGENCY STOP versions according to EN
60204-1 are also available. Additional lagging/leading auxiliary
contacts guarantee double safety for extreme switching conditions. The
safety switches feature an installation-friendly design and easily
accessible connection terminals.
Versions in impact-resistant polyamide or glassfibre-reinforced
polyester enclosures provide the high degree of protection IP66 for
safety switches up 180 A. These can be optionally supplied with snap-on
moulded plastic or brass flanges. Safety switches for amperages up to
630 A are supplied in metal enclosures. These can be equipped with
screw-on flanges. The described safety switches at the sizes 210 - 630 A
are also available for explosion group IIB, which is sufficient for
many of the applications.
