Product details

Siemens 5SL4220-8CC SENTRON MCB — 2-Pole D-Curve 20 A

The Siemens 5SL4220-8CC is a SENTRON miniature circuit breaker (MCB) with a D tripping characteristic, rated 20 A at 400 V AC and a 10 kA breaking capacity per EN 60898. It is a 2-pole design occupying 2 modular width units (36 mm wide) on a DIN rail, with an installation depth of 70 mm and overall depth of 76 mm.

The D-curve's magnetic trip threshold (10–20× In) is the key selection parameter: if you are protecting a fixed-speed motor start or a power supply with a large input capacitor bank, this breaker holds through the inrush that a C-curve (5–10× In) would trip.

Integration Notes

Supplementary devices (shunt trip, auxiliary contacts, alarm switch) can be added on the right side via the product extension feature.

Frequently asked questions

Where can I buy the 5SL4220-8CC?

The 5SL4220-8CC is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.

What is the difference between the 5SL4220-8CC and the 5SL4363-7?

The 5SL4363-7 is a 3-pole C-curve 63 A breaker (3 MW wide, 54 mm), while the 5SL4220-8CC is a 2-pole D-curve 20 A (2 MW, 36 mm). The D-curve on the 5SL4220-8CC handles higher inrush currents than the C-curve, and the pole count and current rating differ — they are not drop-in replacements for each other without rewiring the panel.

What is the depth of the 5SL4220-8CC?

The overall depth is 76 mm, with an installation depth of 70 mm behind the DIN rail.

What is the width of the 5SL4220-8CC?

The width is 36 mm, which corresponds to 2 modular width units on a standard DIN-rail panel.

What compliance documentation is available for the 5SL4220-8CC?

The 5SL4220-8CC is designed to EN 60898 (10 kA breaking capacity), is halogen-free and silicon-free, and carries an IP20 rating with connected conductors. It is suitable for overvoltage category III and pollution degree 2 installations. Specific RoHS/REACH/UL documentation should be requested at quote time.
