The Model 410 Auto-Charged Capacitor Trip Device is a high-speed capacitor-type circuit breaker tripping unit. It differs from the conventional capacitor trip device in that it has a self-contained standby power source, which is capable of maintaining full operating voltage for several days. This device is primarily for use with circuit breakers which require some form of AC power for their closing operation: i. e. , circuit breakers having either a stored energy closing mechanism with an AC-operated release coil, or an AC solenoid-operated closing mechanism. There are no field adjustments required. The Model 410 has a cover-actuated safety switch, which discharges the capacitor and disconnects the primary source when the cover is removed. The Model 410 can be tripped manually, or by means of a voltage-sensing or phase loss monitor. Versions are available for 120 VAC or 240 VAC operations.
