Fitted accessories and communication
This variant ships with a shunt trip (STL) release and a complement of auxiliary switches: two auxiliary switches plus one trip alarm switch HQ. That covers remote tripping and status feedback without ordering separate add-on kits. A communication function is built in, which means it can talk to a higher-level controller or BMS for metering and status — no external module required on this order code.
Dimensions and panel fit
The case measures 86 mm deep, 105 mm wide, and 181 mm tall. That depth (86 mm) means it fits standard-depth panel enclosures without protruding past the gland plate, and the 105 mm width occupies three pole spaces on a DIN rail or mounting plate.
