Product details

The Siemens 3VA1020-3ED36-0CF0 is a 3VA1 IEC frame 100 circuit breaker rated for 20 A with a TM210 thermal-magnetic release — fixed overload Ir=20 A, fixed short-circuit protection Ii=16 x In.

Clamp connection terminals accept copper conductors without lug crimping — speeds panel wiring on a DIN-rail assembly. The 3-pole form factor fits standard 3VA1 mounting footprints; the undervoltage release and auxiliary switch are factory-installed, so no field-assembly labor or spare-parts tracking for those accessories.

Frequently asked questions

What is the breaking capacity of 3VA1020-3ED36-0CF0?

Icu = 25 kA at 415 V AC, breaking capacity class N per IEC 60947-2. That rating handles fault currents typical in commercial and light industrial panelboards.

Where can I buy 3VA1020-3ED36-0CF0?

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

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

Fixed thermal overload Ir = 20 A; fixed magnetic short-circuit protection Ii = 16 x In (320 A). No adjustment dials — set-and-forget for a dedicated 20 A load.
