ABB 2CDS384001R0014 S304P-C1 4P 1A 100kA DIN Rail Miniature Circuit Breaker (MCB)

The ABB 2CDS384001R0014 is a 4-pole S300P miniature circuit breaker (S304P-C1) rated at 1 A with a Curve C tripping characteristic and a 100 kA breaking capacity at 415 V AC. It protects DIN-rail circuits against overload and short circuits according to IEC/EN 60898-1 and IEC/EN 60947-2, and carries a UL 1077 interrupting rating of 10 kA at 480Y/277 V AC.

Selection Notes

At 1 A, this S304P-C family member carries a 100 kA Icn at 415 V AC - the highest rating in the S300P-C line - because the very 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. That headroom suits it to protecting control or instrumentation circuits tapped from busbars with high fault levels, where a low-current device still has to withstand a large short-circuit. Curve C's 5-10 x In magnetic trip threshold still applies, so it remains suited to 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.
