Alex 1) This configuration will not be acceptable for reinforced insulation. But (depends on the application) you may have other ways to bypass the need for reinforced insulation.
2) The transorb is not going to be any good for you since it does not solve your lack of insulation problem Ilan Cohen Technical Director, Safety & Telecom Divisions I.T.L (PRODUCT TESTING) Ltd. 26 Hacharoshet St, POB 211, Or Yehuda, Israel.

The circuit intended to become SELV is accessible to the operator. Questions: 1. Is the combination of Basic Insulation + Fuse&Transorb(15V) equivalent to Reinforced Insulation? 2. Does the transorb have to comply with a specific EN safety standard (like one applicable to Y caps)? Thanks, Alexandru Guidea CAE Inc.
