What the ratings mean for fit
The Siemens Betagard 5SL7202-7RC is a 2-pole miniature circuit breaker rated 415 V AC with a C-curve tripping characteristic. The 15 kA breaking capacity per EN 60898 covers most commercial and light industrial panelboard applications; the 20 kA rating per IEC 60947-2 gives headroom for higher-fault installations where the upstream transformer is close. The C-curve means the magnetic trip operates at 5 to 10 times rated current — standard for motor and lighting circuits where inrush is moderate. The 2-pole design switches both phase and neutral, and the 2-module-width (18 mm per pole) footprint fits standard DIN-rail enclosures. Rated for industrial environments with overvoltage category III and pollution degree 2, this MCB is suitable for fixed installations inside control panels. The IP20 rating applies with conductors connected — the breaker itself is not sealed against washdown, so it belongs inside a cabinet, not on the machine exterior.
Integration and compliance
Mounts in any position on a DIN rail. Depth is 76 mm, installation depth 70 mm — verify enclosure depth clearance if retrofitting into a shallow panel. The 18 mm width per pole (36 mm total for 2 poles) occupies two modular units. Sealable, halogen-free, and silicon-free construction suits environments where outgassing or contamination is a concern. Vibration resistant per IEC 60068-2-6, with a mechanical service life of 10 000 operating cycles typical. Power loss is 1.2 W per pole at rated current in hot operating state — negligible for thermal budgeting in a populated enclosure.
