Emerson Edco PB Series

Alpine Power Systems' experienced technical support & sales team is here to assist your needs:

The Edco PB modules are solid-state protectors for Intercom Extension Pairs. As a new alternative to the “OPX”, the standard Edco intercom protector, the PB adds fusing and a new component layout. These hybrid protectors are intended to be used in conjunction with the Edco MGB ground rail and a standard MI-50 punch down block. The PB 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.

Features and Benefits:

  • Over current protection
  • Replaces bridging clips on M1-50 bock
  • UL 497B listed
  • Utilizes MGB grounding rail
  • Test point accessible
  • 5-year warranty
