INTEGRATED SAFETY A world first: Certified BLOCK FAIL-SAFE transformer for input voltages 230 V and 400 V.


The primary-side concept of the BLOCK FAIL-SAFE transformers guarantees continually safe power interruption in the event of short circuit or overload – now also available for 400 V. This provides complete safety for users and the environment. As such, additional protection is no longer needed.
The VDE Testing and Certification Institute in Offenbach, Germany has confirmed compliance with standards and therefore the safe function of BLOCK FAIL-SAFE transformers, meaning that they have been awarded the ENEC and VDE mark.
The BLOCKIMPEX vacuum impregnation ensures a very high level of corrosion protection and low noise. Up to 160 VA, the BLOCK FAIL-SAFE transformers are equipped with a combi footplate, optionally available for screw or DIN rail mounting.
