Product details

The Siemens 3VA1020-3ED36-0AA0 is a SENTRON molded case circuit breaker rated 20 A continuous at 40 °C, with a TM210 thermal-magnetic release that provides adjustable short-circuit pickup up to 320 A. The 3-pole design suits three-phase line protection in switchboards, motor control centers, and feeder panels.

Integration notes

Dimensions: 70 mm deep, 76.2 mm wide, 130 mm tall — fits the 3VA family cutout. The TM210 release is field-adjustable for short-circuit pickup (li max 320 A), but the thermal element is fixed at 20 A.

Interrupting ratings drop with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 500 V and 690 V. At 500 V DC the maximum rated operational voltage is 500 V DC — check the 3VA DC manual for DC switching limits.

Frequently asked questions

What is the rated current of 3VA1020-3ED36-0AA0?

It is rated 20 A continuous at 40 °C, derating to 19 A at 60 °C and above. The thermal element is fixed; short-circuit pickup is adjustable up to 320 A via the TM210 release.

Where can I buy 3VA1020-3ED36-0AA0 and how is it quoted?

The part is sourced to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What compliance documentation does Siemens provide for this MCCB?

The SENTRON 3VA series carries IEC 60947-2 certification. For specific RoHS, REACH, and UL documentation, request the manufacturer's declaration at quote time — the evidence does not list individual certs for this order code.
