Load break switch, size h1600, 4-pole, 1250A. The load break switch in accordance with DIN EN 60947-3, size h1600, is used to switch electrical systems and networks. The load break switch separates the incoming side from the outgoing side in electrical systems. Mounted on a mounting plate. The three different operating states can be identified by the position of the knob (ON = top, OFF = bottom, tripped = middle position). The switches have a mechanical test button. The function of the circuit breakers can be expanded using various accessories. Including phase separators and connection lugs.
