This Siemens 3VA6210-5KM31-0AA0 is a 3-pole molded-case circuit breaker designed for system protection. It features an operational current of 100A at temperatures up to 70°C and a voltage rating of 690V.
The circuit breaker provides adjustable overload protection (Ir) from 40A to 100A and adjustable short-circuit protection (Ii) from 1.5 to 12 times the nominal current. It also includes adjustable ground-fault protection (Ig) from 0.2 to 1 times the nominal current with a response time (tg) adjustable from 0.05 to 0.8 seconds. The tripping function for ground faults can be set to I2t=ON/OFF.
With a mechanical service life of typically 20,000 switching cycles and electrical endurance ratings up to 7,500 cycles at 600V, this breaker is built for durability. It meets IEC 60947 standards with a breaking capacity (Icu) of up to 85 kA at 240V and UL 489 standards with a breaking capacity of 35 kA at 480V.
The unit has a height of 7.8 inches (198 mm), a width of 4.1 inches (105 mm), and a depth of 3.4 inches (86 mm). It is designed for DIN rail mounting and features a lever actuator. The breaker also supports communication and other measurement functions.
