Product details

Four poles suit three-phase plus neutral or dual-feed configurations. Panel integration: the 70 mm depth and 140 mm width fit standard MCCB mounting footprints — verify the existing bus-bar drill pattern against the 158 mm height before committing the gland plate.

Breaking capacity across voltage classes

The interrupting rating drops with system voltage as expected: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. For a 480 V panel the relevant figure is the 440 V or 500 V entry — the 75.6 kA at 440 V is the conservative reference for 480 V class applications.

Thermal derating and auxiliary configuration

Rated current holds at 200 A from 40 °C through 50 °C (–), then derates linearly: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C. The maximum power loss is 42 W.

Frequently asked questions

What is the breaking capacity of 3VA1220-6EF42-0KH0 at 480V?

The datasheet provides 75.6 kA at 440 V and 30 kA at 500 V. For a 480 V system, the 440 V figure (75.6 kA) is the conservative reference.

What auxiliary switches and releases come with this MCCB?

It includes a shunt trip release (STL), two auxiliary switches, and one trip alarm switch HQ. No undervoltage release or ground-fault monitoring is fitted.

Where can I buy 3VA1220-6EF42-0KH0 and get current pricing?

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 commercial offer.

Will 3VA1220-6EF42-0KH0 drop into a panel specified for 3VA1110-5ED36-0AC0?

Both are SENTRON 4-pole MCCBs, but the 3VA1220-6EF42-0KH0 is a 200 A frame versus the smaller 3VA1110 frame. Physical dimensions and bus-bar centers differ — verify the mounting footprint and lug spacing against the existing panel layout before substitution.
