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.
