Data sheet Weidmller Interface GmbH & Co. KG ADT 2.5 4C Klingenbergstrae 26 D-32758 Detmold Germany www.weidmueller.com Product image In some applications it makes sense to add a test point or a disconnect element to the feed through terminal for testing and safety purposes. With test disconnect terminals you measure electric circuits in the absence of voltage. While the disconnecting points clearance and creepage distance is not assessed in dimensional terms, the specified rated impulse voltage strength must be proven.
