The Siemens 3VA5180-6EF36-0AA0 is a 3-pole molded-case circuit breaker from the 3VA5 series, designed for system protection applications. This breaker features an operational current rating of 80A at 40°C and a maximum breaking capacity of 65kA at 480V, with higher capacities at lower voltages according to UL 489 standards.
With a rated operational voltage of 690V AC and an insulation voltage of 800V, this circuit breaker is suitable for various industrial and commercial power distribution systems. It incorporates TM240 overcurrent release with LI protection function, offering adjustable overload protection (Ir) from 64A to 80A and short-circuit protection (Ii) from 5 to 10 times the rated current.
The breaker is built for durability, with a typical mechanical service life of 20,000 switching cycles and electrical endurance ratings varying by voltage and load conditions. It is designed for DIN rail mounting and features a lever actuator for ease of operation. The HACR Type designation indicates its suitability for Heating, Air Conditioning, and Refrigeration circuits as per UL 489.
Key technical data includes a maximum power loss of 19.3W and an active power loss per pole of 6.43W under rated conditions. The unit weighs 0.811 kg.
