The 5SL4410-0RC is a Siemens Betagard miniature circuit breaker rated 10 A at 415 V AC, 4-pole, with a Z tripping characteristic and 10 kA breaking capacity per EN 60898. The Z curve trips between 2 and 3 times rated current — designed for semiconductor or sensitive electronic loads where standard B/C curves would nuisance-trip on inrush.
Temperature derating and environmental limits
Rated current holds at 10 A up to 50 °C ambient; above that, derate linearly to 9.5 A at 60 °C. The breaker operates from -40 to 75 °C, storage included, so it handles unheated electrical rooms or outdoor enclosures.
Snap-on DIN rail mount, any position. Installation depth 70 mm behind the panel surface; overall depth 76 mm includes the front toggle. Sealable with a lead seal or adhesive label for LOTO compliance. Halogen-free and silicon-free construction, suitable for clean-room or marine environments where outgassing is restricted.
