The Siemens 5SL5825-7 is a 2-pole miniature circuit breaker rated 25 A with C-curve tripping characteristic, breaking 6 kA at 110 V DC. That 6 kA DC rating is the one that matters for DC circuits — AC breaking capacity is higher but the DC figure governs fit for battery banks, DC bus feeds, or solar combiner boxes. The C-curve means it holds through moderate inrush (motor starts, capacitor banks) and trips fast on hard shorts.
Lifecycle status is current/active. No end-of-life notice on record, so this part is still in standard production. For a BOM freeze or spares kit, you can spec it without worrying about a near-term LTB. RoHS compliance effective 28-02-22; REACH Article 33 duty applies due to lead content above 0.1% w/w — factor that into your substance declaration if you ship into EU markets.
