Shunt Trip Safety Switch

Application Description

Eaton’s tried and true heavy- duty safety switch line expands to include shunt trip capability—remote switching and visible means of disconnect for commercial and industrial applications.

The shunt trip technology enhances safety by providing a means to open a safety switch electronically. When using an emergency stop, safety interlock, or similar means, the remote operation capability of the shunt trip switch no longer requires personnel to manually open the switch with the handle, enhancing safety and improving productivity.

The shunt trip safety switch builds on Eaton’s extensive portfolio of safety switch solutions, incorporating a side-handle operation mechanism and visible blade indication that have decades of successful installation and operation.

The shunt trip safety switch can be configured to meet the needs of safety applications in industrial and commercial environments. The switches can be signaled to electronically operate the trip mechanism and interrupt the flow of power when a defined electrical condition is detected via protection relay (for example, ground fault, Undervoltage, blown fuse shutdown).

Application Examples

  • E-stop
  • Safety interlocking
  • Machinery OEM interlocking
  • Remote opening (distant from the switch)
  • Cost-effective solution for high-interrupt applications
  • Ground fault
  • Phase reversal/phase loss 1
  • Blown fuse shutdown
  • Undervoltage release

Note

The shunt trip switch provides a solenoid/coil to facilitate shunt trip, specific relay, and applicable power supply provided by others.
