This Siemens 3VA6210-5HL31-0AA0 is a molded-case circuit breaker from the SENTRON series, designed for system protection applications. It features a 3-pole configuration and an operational current of 100A across various temperature ratings.
The circuit breaker is built with an ETU320 electronic trip unit and supports LI (Long-Time and Instantaneous) protection functions. It boasts a high breaking capacity according to both IEC 60947 and UL 489 standards, with a maximum short-circuit current (Icu) of 85 kA at 240V and 35 kA at 480V (UL).
Key electrical specifications include an insulation voltage of 600V and adjustable overcurrent response settings for Ir (40A-100A) and Ii (1.5-12 x In). The mechanical service life is typically 20,000 switching cycles, with electrical endurance varying by voltage and load conditions.
Mechanically, the unit has dimensions of 198mm height, 105mm width, and 86mm depth. It is designed for DIN rail mounting and has a front protection class of IP40. The operating temperature range is from -25°C.
