Product details

Its 200 A rated continuous current (Iu) holds flat from 40 °C to 50 °C, then derates to 176 A at 70 °C, so the thermal curve is stable across most switchroom ambient conditions without oversizing. The 4-pole construction handles three-phase-plus-neutral systems, and the TM240 overcurrent release provides fixed thermal-magnetic protection — no electronic adjustment, but no programming either. The 187 kA interrupting rating at 240 V and 121 kA at 415 V give serious fault-current headroom for industrial mains; at 690 V it still clears 17 kA, which covers most motor-drive line-side applications. The integrated auxiliary trip accessory (3VA9608-0BB11) is already specified, so no separate order for shunt or UVR add-ons.

The breaker measures 140 mm wide × 158 mm high × 70 mm deep — a standard 4-pole MCCB footprint for 200 A class. The undervoltage release and auxiliary contacts are wired at the factory; no field assembly of trip units is required.

Frequently asked questions

Where can I buy 3VA1220-5EF42-0BC0 and how do I get a price?

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 3VA1220-5EF42-0BC0's interrupting capacity at 415 V?

It is rated 121 kA at 415 V, which covers most industrial mains fault levels.

Does this MCCB include an undervoltage release?

Yes, an undervoltage release (UVR) is integrated — the breaker trips on loss of control voltage.
