Product details

C-curve trip for motor and lighting circuits

The Siemens 5SJ4202-7HG42 is a 2-pole miniature circuit breaker from the SENTRON 5SJ4 series, rated 10 kA breaking capacity per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC.

AC and DC voltage ratings

Rated 400 V AC and 60 V DC maximum, the 5SJ4202-7HG42 covers single-phase branch circuits in 400/230 V distribution panels and low-voltage DC control circuits up to 60 V. The 2-pole design switches both phase and neutral (or two line conductors) in a single 36 mm-wide module, fitting standard DIN-rail enclosures.

Current production and sourcing

Listed as current production. No official cross-reference or direct replacement is on record — confirm the BOM position count and the panelboard compatibility before specifying.
