This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The steep drop at 690 V means it is not a primary choice for 690 V line-side protection unless fault current is tightly bounded; at standard 400/415 V distribution levels the 121 kA rating handles most industrial service-entrance and feeder applications.
Maximum power loss is 28 W, manageable for enclosed panel thermal budgets.
This part is sourced to order against an RFQ through independent distribution. Submit a request for quote to confirm current availability and pricing.
The breaking capacity is 121 kA at 415 V.
Yes, it is equipped with an undervoltage release (UVR) as the auxiliary release.
