Application
The devices are climate-proof and suitable for marine
applications.
Safety EMERGENCY-STOP pushbuttons according to
ISO 13850/EN 418
For controls that comply with IEC 60204-1 or EN 60204-1
(VDE 0113 Part 1), the mushroom-head pushbuttons of the
3SB2 series are suitable for use as safety EMERGENCY-STOP
pushbuttons.
Safety circuits
The standards IEC 60947-5-1 and EN 60947-5-1 require positive
opening. Hence for the purposes of personal safety, the assured
opening of NC contacts is expressly stipulated for the electrical
equipment of machines in all safety circuits and marked accord-
ing to IEC 60947-5-1 with the symbol
Category 4 according to EN 954-1 can be attained with the
EMERGENCY-STOP mushroom pushbuttons if the correspond-
ing failsafe evaluation units are selected and correctly installed,
e.g. the 3TK28 safety relays or matching units from the ASIsafe,
SIMATIC or SINUMERIK product ranges.
