What this 4-pole MCB does on the line
The Siemens 5SL4604-7 is a 4-pole (3P+N) miniature circuit breaker from the SENTRON 5SL4 series, rated 4 A with a C-curve tripping characteristic. The integrated neutral pole switches the neutral conductor, which simplifies wiring in single-phase or three+N distribution boards.
Panel fit and wiring constraints
The 5SL4604-7 occupies 4 width units (72 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. It accepts solid or stranded conductors from 0.75 mm² up to 25 mm², with a recommended tightening torque of 2.5 to 3 N·m on the screw terminals.
It is designed for any mounting position, which gives flexibility in tight enclosures. The overvoltage category is 3, and the energy limiting class is 3 — meaning it limits let-through energy effectively for downstream equipment protection. The product carries the standard Siemens compliance documentation for CE, RoHS, and REACH; specific UL or IEC certificates are available on request with the order.
