• Type A
Cement-coated, wire-wound, tube-type fixed resistors in screwed-on
condition, with side walls and perforated cover, fixed parallel to the
mounting surface, with two connections wired to porcelain terminals in the
mounted terminal box with conduit thread connection.
• Type B and C
Fixed resistor in steel grid version. Depending on the power, with 2 flat
terminals, 2 stud terminals M6 or M8.
The specified braking power is valid for the mentioned relative duty cycle
(ED) of 6 %, 15 %, 25 %, 40 %, and 60 %, relative to a load cycle of
120 s.
Obviously, other duty cycles are allowed as well. The required clearing
time is reduced in the same ratio.
