Product details

The Siemens 3VA1140-5EE42-0AA0-ZD00 is a 4-pole IEC molded-case circuit breaker on the 3VA1 frame, sized for line protection in 40 A circuits where a 55 kA interrupting capacity at 415 V is required. The thermal-magnetic TM220 trip unit gives adjustable overload protection (Ir = 28 A to 40 A) and a fixed short-circuit pickup at 10× In (400 A), so the same breaker can be dialed in for a 32 A motor feeder or a 40 A lighting panel without swapping hardware.

Deployment context

The 4-pole configuration (three phases plus switched neutral) suits a TN-S or TN-C-S system where the neutral must be disconnected for isolation. The N conductor unprotected note means the neutral pole does not carry a trip element; it switches only, so the breaker relies on the phase poles for overcurrent sensing.

Frequently asked questions

Where can I buy 3VA1140-5EE42-0AA0-ZD00 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ through the storefront for a firm commercial response.

What is the breaking capacity of this breaker?

The interrupting capacity (Icu) is 55 kA at 415 V, which is the class M rating on the 3VA1 IEC frame — sufficient for high-fault industrial mains where the available short-circuit current exceeds standard 25 kA or 36 kA breakers.

What does the TM220 trip unit mean for adjustment?

The TM220 thermal-magnetic trip provides adjustable overload protection from 28 A to 40 A (Ir) and a fixed short-circuit pickup at 10× In (400 A). The thermal element is calibrated for the 40 A frame; the magnetic element responds instantaneously above the pickup threshold.
