1 By special order it is possible to complete the CBs with entries with an increased creepage distance. .2 By separate order 3-amp current release can be supplied. 3 By a separate order, they can be supplied with independent release of direct current at a voltage of 110 V.4. By way of a separate order, additional CSAs are installed (6 N.W. + 6 N.O.).5 By request, a second shut-off electromagnet is installed, except for the PEM-UETM®-3 version.

Note:1. For circuit breakers with dependent drive power, the operating voltage range of the alternating current at the rectifier terminals is 200-242 V. The single-phase transformer power to supply the rectifier is at least 25 kV • A. This ensures the inclusion of a latching on short circuit currents up to 12.5 kA. No inductive energy storage required.2. If it is necessary to increase the number of signal circuits, it is allowed to use both (closing and opening) contacts of the BKM node provided that the circuits have a common point (a jumper is installed between the closing and opening contacts of the BKM) and do not carry an inductive load.
