Product details

The Siemens 3VA1140-3ED42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker from the 3VA1 series, rated for line protection with a TM210 thermal-magnetic trip unit. Overload protection is fixed at 40 A (Ir = 40 A), and short-circuit protection trips at 10 × In (Ii = 10 × In).

Integration Notes

Mounts in a standard DIN-rail enclosure or direct panel mount via the frame lugs. The 4-pole configuration covers three-phase plus neutral; note the N conductor is unprotected (solid neutral), so the breaker does not provide neutral overload or short-circuit protection — the neutral bar is a pass-through.

Frequently asked questions

Where can I buy 3VA1140-3ED42-0AA0-ZD00?

This part is available to order against an RFQ through our independent distribution channel. Submit a request for quote to confirm current availability and pricing.

What does the 25 kA breaking capacity at 415 V mean for my panel?

The 25 kA Icu at 415 V means this breaker can safely interrupt fault currents up to 25,000 amps at 415 VAC without failing or requiring an upstream breaker to clear the fault — critical for achieving selective coordination in a 400 V distribution system.

What is the short-circuit protection setting on this breaker?

The magnetic short-circuit pickup is fixed at 10 × In, so for this 40 A breaker, instantaneous trip occurs at 400 A. This is a non-adjustable setting on the TM210 trip unit.
