Our Helio Box junction box dedicated to photovoltaic applications is fitted with Surge Trap® protective devices.
Surge Trap® are designed with a TPMOV™ as a core. TPMOV™ is a metal oxide varistor with a built-in and patented self-disconnecting system. Surge Trap® provide an optimized safety to photovoltaic equipment and installations. Indeed disconnecting via a fuse in series is not possible due to too low fault current and via a breaker let the user without any protection against overvoltages.
Before the end of life of the Surge Trap, the result of disconnecting is visible in front via an indicator.

UNI series Features
This general purpose filter with single phase input is proposed in a very compact size. It can be mounted as desired or attacked directly on the device through biadhesive. The RC + Varistor is a particularly interesting serie because it allows to use the filter without considering the load. In fact it is enough to choose the operation voltage and the circuit RC + Varistor will do the suppressing action in the better way.

MEASUREMENT & CONTROL
Measurement and control devices are highly sensitive and exposed to overvoltages and they do therefore require fine protection for they can withstand a small level of residual voltage (level of protection) from upstream protectors.
Terminal connector based protectors
The BNV series of surge protective devices has been designed for protection of analog and digital signals against transient overvoltages. These devices do both provide common mode and differential mode protection along with built-in disconnection.
