The Siemens 5SL42407RC miniature circuit breaker is designed for reliable overload and short‑circuit protection. It offers precise tripping characteristics, high breaking capacity, long mechanical and electrical life, and compatibility with Siemens distribution boards and enclosures.
It is widely used in residential, commercial, and industrial distribution boards, control panels, feeder circuits, and final sub‑circuits requiring dependable protection.
It automatically disconnects the circuit when overload or fault currents exceed the set limits, helping prevent cable overheating, equipment damage, and potential fire hazards.
Check the rated current, number of poles, breaking capacity (kA), tripping curve (B/C/D), system voltage, and coordination with upstream and downstream protective devices.
Ensure correct DIN‑rail mounting, proper line and load connection, torque tightening of terminals, and adherence to Siemens wiring diagrams and local electrical standards.
Pricing varies based on rating, poles, and series. Visit Electrihub to view current Siemens MCB prices, offers, and stock availability.
