Abstract
A protective house-wiring switch with an overcurrent tripping device in a housing containing terminals for phase conductors and a neutral conductor, contacts for interrupting at least the phase conductors, at least one switch latch having at least one device connected to the respective phase conductors for actuating the contacts to interrupt the phase conductors, includes two overvoltage arresters for each phase conductor connected in cascade in direction of energy flow within the housing, one of the two overvoltage arresters being connected to the respective phase conductor ahead of the contact actuating device, and the other of the two overvoltage arresters being connected to the respective phase conductor after the contact actuating device.
