Current Transformer Protection Units

Used to prevent dangerous voltages in transformer applications, Metrosil Current Transformer Protection Units (CTPU) are designed to deliver superior protection when the secondary side becomes open. Our CTPU devices are connected across the secondary side of the CT to provide permanent protection without the need for user intervention.

CTPU Enclosures

Metrosil’s range of pre-assembled CTPU Enclosures provide advanced shielding against the damaging effects of secondary side open circuits. Type tested and independently certified to IEC 61439 Parts 1 and 2, the units are available in adaptable configurations and flexible fitting options to suit specific application needs.
