Short description
KT plug-in electrical connection with screw-type terminals for power connection and
spring clamp terminals for control contacts.
KM version with additional support terminals (terminal blocks) via terminal carrier.
Both versions (KT and KM) are available with terminal compartment in protection
type Ex e (increased safety) as well as in protection type Ex d (flameproof enclosure)
(refer to Ex marking on name plate).
Plug-in connection is made via the connection frame. For cable connection, simply
remove the cover. The connection frame with the cable entries remains within the
device. The flameproof interior of the connected devices remains sealed.
