ASCO Model 130 (Edco PB Series) Surge Protective Device

The ASCO Model 130 modules are solid-state protectors for Intercom Extension Pairs. These hybrid protectors are intended to be used in conjunction with the ASCO MGBW ground rail and a standard M1-50 punch down block. The Model 130 modules feature solid-state resettable fuses (PTCs) between the protected equipment and the over voltage clamping components. This unique design prevents problems with “All-Call” in the event of catastrophic protector failure.
