The 15 kA breaking capacity matches typical industrial panel fault levels at 415 V; if your SCCR study shows higher available fault current upstream, this breaker is not the right fit. The 2-pole design switches both phase and neutral simultaneously, but the neutral is not switched independently — the product component entry confirms no neutral conductor switching, so it is a solid-neutral configuration. For applications requiring a switched neutral, look at a 1P+N or 3P+N variant in the same family. Thermal derating is published from 30 °C upward: 20 A at 30 °C, 18.8 A at 40 °C, 18.2 A at 45 °C, 17.4 A at 50 °C, 16.8 A at 55 °C, 16.2 A at 60 °C. If the breaker lives in a sealed enclosure or near heat sources, use the 40 °C or 50 °C column for continuous load sizing — not the 30 °C figure. Snaps onto standard DIN rail. Width is 18 mm (2 modular width units), depth 76 mm, height 90 mm, with a 70 mm installation depth behind the panel surface. Mounting position is any orientation — no derating for sideways or inverted mounting. ## Approvals and compliance documentation Rated and tested to EN 60898 and IEC 60947-2, which are the governing standards for miniature circuit breakers in residential/commercial (EN 60898) and industrial (IEC 60947-2) installations. The 15 kA breaking capacity applies under both standards, meaning the same hardware meets both the domestic and industrial certification paths.","metaTitle":"Siemens Betagard 5SL7220-8RC MCB, 2P D 20 A 15 kA","metaDescription":"Siemens Betagard 5SL7220-8RC miniature circuit breaker, 2-pole, D-curve, 20 A rated, 15 kA breaking capacity per EN 60898.
