In the switch, a lockable lever that can be twisted from the front (lockable in the OFF position). The switch is 4-pole (can be connected to either 4- or 2-pole series).

Nominal voltages and current values (examples):

• 1500 VDC (DC21B), nominal current 25 A (when connected in 4-pole series, one string)
• 1000 VDC (DC21B), nominal current 11.5 A (when connected 2 x 2 poles in series, i.e. two strings)

There are two M20/M25 breaching blanks in the upper and lower part of the case. The delivery includes four M25 sleeve seals with rubber seals for four 6-8 mm DC cables.
