STC-SS Series - Data/Signal Line Protection

The STC-SS Series suppressors are designed for the
water and wastewater industry. These multi-stage hybrid
suppressors address overvoltage transients with gas tube
and silicon avalanche technology. In addition, sneak and
electrical fault currents are mitigated with PTC devices
which consist of solid-state resettable fuses. The units are
encapsulated in stainless steel pipe nipples making them
suitable for use in severe environments.
