Square D’s 30.5mm are now be
supplied with a new type of contact block that makes them easier to use
and more versatile. Pushbuttons fitted with the new blocks are fully
interchangeable with older versions and, like their predecessors, meet
the requirements of BS EN 418 and BS EN 60947-5-5 for ‘tease-proof’
trigger action and latching operation.
The T-Series products are IP66 protected and are supplied assembled with
a choice of 35mm or 57mm diameter red mushroom heads. Versions with a
neoprene protective cap are also available to provide additional
protection in some industrial environments. All types are offered with
one or two normally closed contacts, but where additional normally open
contacts are required, these can be provided by using a Telemechanique
Preventa XPS-AF safety relay.
