Product details

This MCCB's interrupting rating varies with line voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. The 242 kA at 240 V covers most North American 277/480 V panelboard mains where the line-to-ground fault can be extreme.

Built-in monitoring and communication

That means it can report trip events and leakage current over a bus to a PLC or energy management system — useful for a plant engineer trying to isolate a recurring fault without walking every panel. The other measurement function listed suggests it can also track energy or power quality data through the same comms link.

Frequently asked questions

What is the breaking capacity of this MCCB at 415 V?

The breaking capacity is 187 kA at 415 V, which also applies at 440 V. At 240 V it rises to 242 kA; at 690 V it drops to 3 kA.

Where can I buy the 3VA2040-6KQ32-0AA0 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 price and lead time.

Does this breaker have ground-fault monitoring?

Yes, it includes a ground-fault monitoring version using summation current formation on the L-conductor, plus an additional measurement function for energy or power quality data.
