Product details

The 3VA1580-5EF32-0AJ0 is a Siemens 3VA1 IEC frame 1000 circuit breaker rated Icu=55kA at 415V AC, class M breaking capacity. The 3-pole construction and TM240 thermal-magnetic trip unit with ATAM (adjustable thermal, adjustable magnetic) give you overload protection adjustable Ir=560A to 800A and short-circuit protection fixed at Ii=5×In.

Built-in auxiliaries and trip alarm

The aux switches give remote status of the main contacts — open/closed — while the trip alarm signals a fault trip independently of the handle position. That matters for a PLC-based monitoring scheme: you get two separate signal paths, so a remote I/O card can distinguish a manual open from an overcurrent trip without extra wiring.

Frequently asked questions

What is the breaking capacity of this breaker?

Rated Icu=55kA at 415V AC, class M breaking capacity per IEC 60947-2. That is the maximum short-circuit current it can safely interrupt at that voltage.

What are the overload and short-circuit protection settings?

Overload protection Ir is adjustable from 560A to 800A via the TM240 thermal-magnetic trip unit. Short-circuit protection Ii is fixed at 5×In (4000A for In=800A).

Where can I buy 3VA1580-5EF32-0AJ0 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is listed here, but a quote request will return both.
