The Siemens 5SL5810-7 is a 2-pole miniature circuit breaker rated 10 A with a C tripping characteristic, interrupting 6 kA at 110 V DC. The C curve means it handles moderate inrush — typical for motor starters, small transformers, and lighting banks — without nuisance trips. At 18 mm per pole (1 MW), it fits standard DIN-rail enclosures; two poles occupy 36 mm total.
