The ABB 2CCS473001R0045 is a B-curve miniature circuit breaker rated 4 A, 3-pole, with a rated insulation voltage of 440 V and a short-circuit breaking capacity of 10 kA (both Icn and Icu).
Overvoltage category III confirms it's rated for fixed-installation distribution panels, not just downstream equipment.
The 69 mm width (3 module widths at 18 mm each) fits a standard distribution board.
Both Icn and Icu are rated 10 kA at 440 V, meaning it can safely interrupt a short-circuit fault up to that level.
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 commitment.
It has a B-curve characteristic, tripping instantaneously between 3 and 5 times the rated current (12 to 20 A for this 4 A unit), suited for resistive and small inductive loads.
