Product details

The Siemens 3VA1020-4ED36-0DA0 is a SENTRON molded case circuit breaker (MCCB) built for line protection in commercial and industrial distribution panels. It's a 3-pole unit rated 20 A at 40 °C, with a breaking capacity of 75.6 kA at 415 V AC — enough to handle heavy fault currents on a 400 V class feeder without cascading upstream. The built-in undervoltage release (UVR) lets you trip the breaker on loss of control voltage, which is handy for emergency-stop circuits or mains-supervision schemes.

The 3VA1020-4ED36-0DA0 fits a standard 76.2 mm wide (3-inch) DIN cutout, 130 mm tall, 70 mm deep. That 70 mm depth is shallow enough to clear most gland plates and back-panel wiring — no need to oversize the enclosure just for this breaker. The TM210 thermal-magnetic trip unit is fixed, so there's no interchangeable trip to order separately; it's a straight drop-in for a 20 A feeder.

Frequently asked questions

Where can I buy the 3VA1020-4ED36-0DA0 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is the breaking capacity at 415 V?

75.6 kA at 415 V AC — that's the interrupting rating for typical 400 V class industrial feeders.
