Engineered Fusible Shunt Trip Disconnect

Ferraz Shawmut’s Engineered Switches offer modular industrial control panels featuring a fusible shunt trip to allow for remote disconnection. An array of available options allows for maximum functionality to be built in a single compact panel. Panels built for elevator applications feature control transformers (fusing both primary and secondary sides), a fire safety interface relay with a fire alarm voltage monitoring relay and mechanically interlocked auxiliary contacts. Use of Ferraz Shawmut’s Amp-Trap 2000® AJT Class J fuses permits easy selectivity coordination, while providing the panel and its components with superior current limitation and the ability to withstand high fault conditions. AJT fuses provide added system reliability since no maintenance or periodic testing is required as with other electromechanical over-current devices.

  • Industrial Control circuit transformer Primary (208, 240, 480 or 600 VAC)
  • Fire safety relay for control interface (DPDT Relay, choice of Coil Voltage: 120 VAC, 24 VDC or 24VAC)
  • Oil-tight Key Switch to test 2 position selector switch.
  • Oil-tight Power enabled power light (choice of lens colors: Red, Green, White or Yellow) to terminals Isolated neutral lug – 100%.
  • Oversized 200% for excessive Non-Linear loads.
  • Auxiliary and Alarm Contacts are both Form C contacts. The Auxiliary contacts change state when the switch is in the on position. Alarm contacts change state when the switch is in the tripped position. The Alarm contact is located in place of the second auxiliary contact.
  • NEMA 12, 3R, 4 or 4X enclosure available.
  • Fused switch – provides high current limitation and short circuit withstand
  • Padlockable handle – permits panel to be locked with switch in the off position ensuring load side power isolation during servicing
  • Shunt trip – permits for remote tripping of the main line power prior to the application of water in elevator sprinkler system applications
