The Siemens 5SJ4215-8HG42 is a 2-pole miniature circuit breaker from the SENTRON 5SJ4 family, with a D tripping characteristic and a rated current of 1.6 A at 40 °C. Rated for AC/DC operation up to 60 V DC, it's suited for control panels in mechanical engineering and industrial environments.
The 1.6 A rating holds steady up to 45 °C ambient. At 50 °C it derates to 1.5 A, and at 60 °C to 1.4 A.
This part is sourced to order through independent distribution. Submit an RFQ for current availability and pricing; stock and lead time are confirmed at quote time.
No. The 5SY4116-7CV is a single-pole B-curve 16 A breaker; the 5SJ4215-8HG42 is a 2-pole D-curve 1.6 A. Different poles, curve, and rating — it requires rewiring and a coordination check.
The depth is 70 mm, which matches the installation depth for DIN-rail mounting.
The width is 36 mm, which corresponds to 2 modular width units on a standard DIN rail.
