What this MCB does in the panel
The Siemens 5SY6013-7KL is a 1-pole+N miniature circuit breaker from the SENTRON series, rated 13 A with a C-curve trip characteristic and a 6 kA breaking capacity at 230 V AC.
Wiring and mounting — what fits
Terminals accept solid or stranded copper from 0.75 mm² up to 16 mm² — covers everything from a 1.5 mm² lighting circuit up to a 4 mm² or 6 mm² feeder. Tightening torque is 2 to 2.5 N·m (17.7–22.1 lbf·in), which is a standard screwdriver setting; no special tooling needed. The neutral conductor is switched internally (1P+N), so this single module handles both phase and neutral protection in a 230 V single-phase circuit. Storage range is wider at -40 to +75 °C.
Durability and compliance marks
Rated for 10 000 mechanical switching cycles — that's the service life of the mechanism under normal operation, not the electrical endurance at full rated current (which will be lower). The sealable design (tamper-evident cover available) is useful for utility-metered or rental installations where you need to lock the breaker position.
