AF-Contactors
General
The AF-Contactors have the same dimensions and nearly the same apperance as
the A-Contactors of equal rating. The only difference is that AF-Contactors are
fitted with an electronic coil interface. For a given coil, this interface allows the
contactor to accept a very wide voltage range a well in d.c. as in a.c. , 50 or 60 Hz.
Control with voltage on A1 and A2
Operatin of AF-Contactors can be done as with conventional contactors by
applaying and removing voltage on A1 and A2. The function limits are very exact
compared with a conventional contactor and there is a built in hysterises in the
function.
Note: Minimum length of the starting pulse=70 ms
AF-Contactors comply with international standards IEC 947-1, IEC 947-4-1 and European standards EN 60947-1, EN 60947-4-1.
Moreover the AF-contactors comply with the EMC requirements environment A in IEC 60947-1, EN 60947-1.
Environment A relates to low-voltage non-public or industrial networks/locations/installations including highly disturbing sources.
Environment A corresponds to equipment class A in CISPR 11.
