ABB 2CDS384001R0064 S304P-C6 4P 6A 100kA DIN Rail Miniature Circuit Breaker (MCB)

Rated at 6 A, the ABB 2CDS384001R0064 (S304P-C6) is a 4-pole S300P miniature circuit breaker with Curve C tripping and a 100 kA breaking capacity at 415 V AC. Built to IEC/EN 60898-1 and IEC/EN 60947-2 and listed to UL 1077 at 10 kA / 480Y/277 V AC, it switches and protects DIN-rail feeder and branch circuits.

Selection Notes

At 6 A, this is the highest-current member of the S304P-C 100 kA group, which also includes the 1 A, 3 A and 4 A frames; above 6 A the family's Icn drops sharply to 25 kA at 10 A. The low let-through energy at this current level keeps the thermal-magnetic trip well within its mechanical breaking limits even at very high prospective fault currents, so it suits infeed or control circuits on boards with high fault levels. Curve C's 5-10 x In magnetic trip threshold still applies, matching loads with inrush rather than pure resistive loads. The 4-pole configuration switches all three phases plus the neutral, which is needed on TN-C-S or TT systems where the neutral must also be isolated.
