The Siemens 5SL6214-7CC is a SENTRON miniature circuit breaker from the 5SL6CC design family, rated 0.3 A at 400 V AC with a C-curve tripping characteristic and a 6 kA breaking capacity per EN 60898. This 2-pole unit occupies 2 width units (36 mm) on the DIN rail and accepts conductors from 0.75 to 25 mm² solid or stranded.
The 0.3 A rated current and C-curve (5–10× In magnetic trip) make this MCB suited for protecting small lighting circuits, control transformers, or instrumentation loops where inrush is moderate. The 2-pole configuration switches both phase and neutral, though the neutral conductor is not switched internally (no neutral switching function per the spec). Vibration resistance at 50 m/s² (25–150 Hz per IEC 60068-2-6) is solid for industrial panels near rotating machinery.
Wiring and installation notes
The 76 mm depth and 70 mm installation depth fit standard distribution boards; 2 width units (36 mm) mean it replaces a 2-pole MCB in any 18 mm-module DIN rail panel. Halogen-free and silicon-free construction is noted for sensitive environments like healthcare or clean-room adjacent panels.
