Siemens 3VA5322-6EC61-0AA0 Molded Case Circuit Breaker

This molded case circuit breaker is rated 225A and 600VAC. Use these ratings when evaluating the circuit's load, conductor protection requirements, and operating voltage.

The interrupting ratings are 100kA at 240VAC, 65kA at 480VAC, and 25kA at 600VAC. Compare the available fault current at the installation point with the rating for the circuit voltage; it must not exceed that interrupting rating.

The thermal-magnetic trip provides long-time overload protection and instantaneous short-circuit protection. The thermal setting is fixed, while the magnetic setting is adjustable, allowing adjustment of the instantaneous trip threshold.

This is a two-pole, single-phase breaker. Use those characteristics when selecting protection for the conductors requiring breaker protection in a single-phase circuit.

The breaker uses unit mounting and measures 9.76 in high, 5.43 in wide, and 4.33 in deep. Use the mounting style and dimensions to plan its mounting layout and physical space.

The breaker has lug terminals, which secure conductors through a clamped connection. Plan conductor termination for lugs and tighten the connections using the applicable installation torque requirements.

HACR refers to heating, air-conditioning, and refrigeration applications. When selecting protection for these circuits, evaluate the HACR rating together with the equipment's required breaker ratings.

The breaker carries UL 489 and IEC 60947-2 standards, with CE, CSA, UL, and VDE approvals. Use these when checking the project's required circuit-breaker standards and approval criteria.

The temperature rating is -25C to 70C. Compare this range with the temperature conditions at the installation location when selecting the breaker.
