Siemens 3VA1 IEC frame 160, breaking capacity class S, 3-pole, line protection TM240, ATAM, In=100A, overload protection Ir=70A...100A, short-circuit protection Ii=5...10 x In, clamp connection, 1 auxiliary switch HQ, 1 trip alarm switch HQ.
The thermal element (overload) is adjustable from Ir = 70 A to 100 A, matching the In = 100 A frame rating. This adjustability lets the panel builder coordinate with downstream feeders without swapping the breaker body.
Includes one auxiliary switch HQ and one trip-alarm switch HQ. The auxiliary reports the breaker's open/closed position; the alarm switch changes state only when the breaker trips on a fault.
Icu = 36 kA at 415 V AC, breaking capacity class S per IEC 60947-2. This is the maximum short-circuit current the breaker can safely interrupt at that voltage.
This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.
Thermal overload Ir adjustable 70 A to 100 A. Magnetic short-circuit pickup Ii adjustable 5 to 10 times In (500 A to 1000 A). The trip unit is a TM240 thermal-magnetic type.
