The Siemens 3VA5170-6ED21-0AA0 is a 2-pole molded-case circuit breaker from the SENTRON series, designed for system protection applications. This breaker features a frame size of 125A with a permanent rated current (Iu) of 70A, adjustable from 70A to 70A for overload protection (Ir) and 700A to 700A for short-circuit protection (Ii).
With a maximum rated operational voltage of 415V AC and 250V DC, it provides reliable circuit protection. The breaking capacity according to IEC standards is 70 kA at 415V and 150 kA at 240V. Under UL 489 standards, it offers a breaking capacity of 65 kA at 480V and 25 kA at 600Y/347V. The breaker is built with a TM210 overcurrent release and an LI protection function.
Mechanically, the unit has a height of 140 mm (5.5 in), a width of 50.8 mm (2 in), and a depth of 76.5 mm (3 in). It is designed for DIN rail mounting and features a lever actuator. The typical mechanical service life is 15,000 switching cycles, with electrical endurance ratings varying based on voltage and load conditions.
This circuit breaker is compliant with CCC, CE, CSA, EAC, UL489, and VDE standards. It is also RoHS3 compliant and has an MSL of 1.
