Product details

It breaks fault currents up to 15 kA per EN 60898 and 20 kA per IEC 60947-2 at 415 V AC.

Rated 20 A at 30 °C ambient, but derate to 18.8 A at 40 °C and down to 16.2 A at 60 °C. The 2-pole configuration (2P design) switches both phase and neutral, or two phases in a split-phase system.

Snaps onto standard DIN rail, 2 modular width units (18 mm per unit, 36 mm total). Installation depth is 70 mm from the rail face; overall depth 76 mm. Mounting position is unrestricted — horizontal, vertical, or upside-down. IP20 with connected conductors, so it belongs inside an enclosed panel, not exposed to washdown or dust.

Frequently asked questions

Where can I buy 5SL7220-7RC and how do I get a price?

Sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.

When sourcing 5SL7220-7RC, what's the closest functional alternative?

The 5SJ6325-7RC is a 3-pole SENTRON MCB with similar 415 V AC rating and C-curve, but it's 25 A rated and occupies 3 MW units (54 mm wide). It won't drop into a 2-pole, 36 mm panel cutout without rewiring and a wider DIN-rail slot.

What is 5SL7220-7RC's listed depth?

Overall depth is 76 mm; installation depth from the DIN rail is 70 mm.

What is 5SL7220-7RC's listed width?

Width is 18 mm per pole, 2 modular width units for a total of 36 mm.

Will 5SL7220-7RC drop into a panel specified around 5SJ6325-7RC without rewiring?

No. The 5SJ6325-7RC is a 3-pole device (54 mm wide, 3 MW units) rated 25 A; the 5SL7220-7RC is 2-pole (36 mm wide, 2 MW units) rated 20 A. The panel cutout, wiring, and load rating all differ.

What compliance documentation does this brand provide for 5SL7220-7RC?

The Betagard series is halogen-free and silicon-free. The breaker is rated per EN 60898 and IEC 60947-2. Standard Siemens documentation includes CE declaration and manufacturer's test certificates.
