The Siemens 5SL4206-7RCZ24 is a high-precision 5SL4 series Miniature Circuit Breaker (MCB) engineered for effective overload and short-circuit protection in commercial, industrial, and automation control systems. Featuring a 2-pole configuration, 6A rated current, and Type C tripping characteristics, this MCB offers a reliable 10kA breaking capacity at 415V AC, ensuring robust defense for low-power control circuits, instrument loops, and sensitive automation equipment.
10kA Short-Circuit Breaking Capacity: Certified for a high short-circuit breaking capacity of 10kA at 415V AC, safeguarding fine wiring and connected devices from severe electrical faults.
6A Rated Current & 2-Pole Design: Safely protects both phases or phase-and-neutral conductors in 2-pole AC electrical distribution circuits.
Type C Tripping Characteristic: Operates instantaneously at 5 to 10 times rated current ($5 \times I_n$ to $10 \times I_n$), making it ideal for loads with moderate inrush currents like small control power supplies, solenoids, contactor coils, and relay logic loops.
Modular DIN-Rail Mounting: Standard compact footprint allows quick, tool-free snap-on mounting on standard 35mm DIN rails inside distribution cabinets.
Finger-Safe IP20 Touch Protection: Terminal shrouds prevent accidental direct contact, providing safety for installers and maintenance personnel.
Industrial-Grade Quality: Built to Siemens SIRIUS/SENTRON quality standards for long mechanical and electrical service life under continuous operation.

Q1: How does the 6A model (5SL4206-7RCZ24) differ from higher current models like 10A or 16A in this series?
A: All models share the same 2-pole, 10kA, Type C design framework; the primary difference is the continuous current rating. The 6A model is calibrated to trip at very low continuous current thresholds, making it ideal for low-power control transformers, instrument loops, and thin-wire circuits.
Q2: What does "Type C" tripping characteristic mean for this MCB?
A: Type C characteristic means the breaker trips instantaneously at 5 to 10 times its rated current, accommodating standard startup inrush surges without nuisance tripping.
Q3: Can this MCB be installed on a standard 35mm DIN rail?
A: Yes, it features a standardized modular housing designed for quick, tool-free snap-on mounting on standard 35mm DIN rails.
Q4: Is this breaker suitable for 415V two-phase or phase-plus-neutral circuits?
A: Yes, its 2-pole construction and 415V AC voltage rating make it well-suited for two-phase or phase-plus-neutral line protection.
