The C60H3P6AD is a 3-pole C60H miniature circuit breaker from the Multi9 range, rated 6 A at 40 °C with a D tripping curve (magnetic trip at 10–14 × In). The 6 A rating means it protects a branch circuit drawing up to 6 A continuous; for motor duty, that usually corresponds to a fractional-horsepower load or a control transformer primary. Breaking capacity is rated per IEC 60947-2: 30 kA Icu at 230–240 V AC, 15 kA at 400–415 V AC, and 10 kA at 440 V AC.
The toggle mechanism provides ON/OFF local indication and a contact position indicator for visual confirmation of isolation. It's certified for isolation per IEC 60947-2, meaning you can safely use it as a disconnecting means for the downstream circuit during maintenance.
