Ethernet Disconnects

Ethernet Secondary Disconnects are secondary dispenser wiring disconnects designed to expand the number and type of cabling that can be disconnected. They are designed for dispensers that use Ethernet network cabling for secondary dispenser communication.

SECONDARY DISCONNECTS

Secondary Ethernet Disconnects expand the capability of the Primary Disconnect. They connect to and are controlled by any Primary Disconnect via the included 6’ and 25’ DB-9 cables. Wall or Rack Mount options available.


Emergency Stop

Secondary Disconnects connect to the Primary Disconnect allowing secondary circuit conductors to be disconnected when the emergency stop system is activated.

Ethernet Disconnect

Handles disconnect for 1 or 2 Ethernet cables for 8 dispensers or disconnect for 1 Ethernet cable for 16 dispensers.

Easy Installation

Individual disconnects for each circuit types allows the disconnect to be located where the conductors enter the building. This can eliminate costly additional wiring and downtime that maybe required to re-route conductors to a central location such as the electrical room, during a retrofit or site upgrade.

Certifications/Approvals

  • cUL Listed 1238.
  • For compliance with NEC® 514.11 and NFPA® 30A Section 6.7 requirements for Emergency Disconnects at Motor Fuel Dispensing Facilities (controlled by E-Stop system).
