• By combination with miniature circuit breaker PLHT => RCBO-Unit (MCCB)

• Add-on residual current unit (screw connection) for 80 or 125 A

(2-pole and 4-pole)

• High flexibility and ease of installation thanks to variable wiring (400 mm

flexible connection wires 2p = 2 units, 4p = 4 units included in the set)

• Free selection of main power supply

• Auxiliary switch 1 NO included as standard in all PBHT versions

• Permits combinations with a variety of characteristics thanks to the different

rated currents and characteristics of the miniature circuit breakers PLHT

which can be connected

• For trade and industry applications

• For subsequent mounting onto 2, 3, 3+N and 4-pole-miniature circuit break-

ers PLHT

• Toggle (serves as switch position- and tripping indicator)

• The screw connection to the PLHT-device can be unscrewed at any time.

Consequently, in case of modifications of the systems to be protected, the

installation can be adapted to new requirements at any time.
