TSF
Transient Surge Filters combines ERICO’s Transient Discriminating (TD) technology, with a low pass filter for transient events, and to attenuate small signal RFI/EMI noise problems. Ideal for PLC controllers, SCADA systems, MCCs, and other critical applications.
SRF
Surge Reduction Filters combine high-energy surge diversion with surge filtering, making these ideal for primary service protection. Their efficient low pass filtering stage also dramatically reduces the rate-of-voltage rise and the let-through.
