Product details

The Siemens 3VA1220-5EF42-0DH0 is a SENTRON molded case circuit breaker (MCCB) rated for 200 A continuous current at 40 °C, with a breaking capacity of 187 kA at 240 V — that's the short-circuit rating that determines if this breaker clears a fault without upstream coordination issues.

Above that it drops to 194 A at 55 °C and 176 A at 70 °C, which is the operating limit (cites:-). Breaking capacity steps down with voltage: 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V — the 187 kA at 240 V is the headline number for high-fault panels (cites:-).

Dimensions: 140 mm wide, 158 mm tall, 70 mm deep — it's a 4-pole frame so the width is the key fit check for DIN-rail or panel-mount spacing (cites:-).

Frequently asked questions

Where can I buy 3VA1220-5EF42-0DH0 and get a price?

This part is sourced to order against an RFQ through independent distribution channels. Submit a request for quote; availability and current pricing are confirmed at quote time.

Will 3VA1220-5EF42-0DH0 drop into a panel specified around 5SQ2670-2YA63?

Both are 200 A 4-pole MCCBs, so the basic fit is similar. But the 3VA1220-5EF42-0DH0 carries an undervoltage release and specific auxiliary switch configuration (2 aux + 1 trip alarm) that may differ from the 5SQ2670-2YA63's wiring — verify the control circuit and mounting hole pattern before swapping.

What are the key ratings for 3VA1220-5EF42-0DH0?

Rated 200 A continuous at 40-50 °C ambient, 4-pole, with a breaking capacity of 187 kA at 240 V and 121 kA at 415 V. Insulation voltage is 800 V. Dimensions are 140 mm wide, 158 mm tall, 70 mm deep.
