Product details

The Siemens SENTRON 5SL4301-7CC is a 3-pole miniature circuit breaker with a C tripping characteristic, rated 1 A at 400 V AC and a breaking capacity of 10 kA per EN 60898.

Above that, the thermal-magnetic element derates: 0.95 A at 40 °C, 0.92 A at 45 °C, 0.89 A at 50 °C, and 0.86 A at 55 °C. If the panel runs warm — say a crowded enclosure near a drive cabinet — factor the actual load against the 40 °C or 50 °C figure, not the 30 °C nameplate.

The housing carries IP20 protection with connected conductors, standard for live-part protection inside a closed panel. The breaker is sealable, halogen-free, and silicon-free, which simplifies compliance documentation for RoHS and REACH tracking.

Frequently asked questions

What are the key ratings of the 5SL4301-7CC?

It is a 3-pole miniature circuit breaker with C-curve, rated 1 A at 400 V AC, with a breaking capacity of 10 kA per EN 60898. The thermal derating curve is provided from 30 °C through 55 °C.

Where can I buy the 5SL4301-7CC and how is it priced?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at the time of quotation — submit an RFQ for a firm quote on your required quantity.

Does the 5SL4301-7CC replace the 5SL4363-7 in an existing panel?

Both are 3-pole C-curve MCBs from the SENTRON 5SL series, sharing the same 3-module DIN-rail footprint and 10 kA breaking capacity. The primary difference is the current rating — this unit is 1 A per pole, while the 5SL4363-7 is a higher-rated variant. If your existing panel was wired for a specific load current, verify the rating matches before substituting; the mechanical fit and wiring layout are identical.
