Notes:
Short circuit protection: Observe the maximum permissible fuse of the contactor with
direct device mounting. See MN03402001E
for more information on overload relays for
Frame B – G.
Suitable for protection of EEx e-motors. EC
prototype test certificate available upon
request.
Observe manuals MN03402001E and
