The TA45-2R series circuit breaker is a thermal device designed to interrupt electrical currents in the event of overload or short circuits. It features a 700 milliampere (mA) current rating and can handle both alternating current (AC) at 240 volts and direct current (DC) at 60 volts. The breaker has a snap-in design for easy installation on a rocker panel mount, providing a secure and efficient means of protecting electrical systems from excessive loads or faults.
