Trigger Actuator

The Trigger Actuator is part of the Mersen (formerly Ferraz Shawmut) disconnect switches line, distributed by Gross Automation.

Trigger Actuator

The Trigger Actuator (catalog number suffix TA) has two functions and is an option available on many Amp-trap fuses. First, it provides visual indication of an open fuse and second, it provides a mount for an Add-On-Switch (AOS-) which can indicate a blown fuse via a signal light or initiate appropriate control action. The Trigger Actuator has no measurable I2t or arc voltage effect on fuses rated 65A or higher. It will add 2 to 5 amperes of long term rating and requires a minimum circuit voltage of 5 to 10 volts to activate.
