GAF-Contactors
General
The GAF Contactors are fitted with an electronic coil interface. For a given
coil, this interface allows the contactor to accept a very wide voltage range
as well in d.c. as in a.c. , 50 or 60 Hz.
Control with voltage on A1 and A2
Operating of GAF-Contactors can be done as with conventional contactors by
applying 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
GAF-Contactors comply with international standards IEC 947-1, IEC 947-4-1 and European standards EN 60 947-1, EN 60 497-4-1. Moreover in
environment 2, they meet the electromagnetic compability rules (EMC): additional clauses A11 and A11 to above mentioned EN standards.
Using these materials in environment 1 may lead to radio-interferences requiring the use of aditional mitigation methods. Here are the definitions
given in the additional clause A11 to standard EN 60 497-1.
Environment 1: "Mainly relates to low-voltage public networks such as residential, commercial and light industrial locations/installations.
Highly distributing sources such as arc welders are not covered by this environment".
Environment 2: "Mainly relates to low-voltage industrial networks/locations/installations including highly distrurbing sources".
According to UL 508:
Use wire Cu 75 C only.
GAF 185: Enclosure with min. dimension 24 by 20 by 10 inches should be used.
GAF 300: Enclosure with min. dimension 36 by 30 by 12 inches should be used.
