Product details

Siemens 5SL4614-8CC — 0.3 A D-curve MCB, 3P+N, 10 kA

The Siemens 5SL4614-8CC is a SENTRON miniature circuit breaker (MCB) with a D tripping characteristic, rated 0.3 A at 400 V AC and a 10 kA breaking capacity per EN 60898. The 3P+N pole design (4 poles total) makes it a three-phase-plus-neutral unit, sized for residential and infrastructure branch circuits where the neutral is switched alongside the phases. At 0.3 A, this is a very low-rated D-curve MCB, suited for protecting control transformers or instrumentation supplies rather than power circuits.

Breaking capacity and voltage ratings

Multi-phase operation is rated up to 440 V AC maximum. The overvoltage category is III (fixed installation), with pollution degree 2. For DC applications, the maximum rated voltage is 72 V. Thermal derating is published: 0.3 A at 30 °C, 0.28 A at 40 °C and 45 °C, 0.27 A at 50 °C, and 0.26 A at 55 °C.

Height is 90 mm. Protection class is IP20 with connected conductors.

Frequently asked questions

Will 5SL4614-8CC drop into a panel specified around 5SL4363-7 without rewiring?

No — the 5SL4614-8CC is 4 MW wide (72 mm) versus 3 MW (54 mm) for the 5SL4363-7, and it is 3P+N (4 poles) versus 3P (3 poles). The DIN-rail clip fits, but the panel cutout and wiring plan must accommodate the extra pole and wider footprint.

What is 5SL4614-8CC used for?

This D-curve 0.3 A MCB protects control transformers, instrumentation supplies, or small inductive loads in residential and infrastructure branch circuits where high inrush current would trip a B or C curve.

Where can I buy 5SL4614-8CC and how is it quoted?
