Product details

The Siemens 5SY6214-8 is a SENTRON 5SY6 series miniature circuit breaker — two-pole, D-curve, rated 0.3 A at 400 V AC.

Installation depth to the rail is 70 mm. Mounting position is unrestricted, which helps when the panel layout forces a horizontal or inverted orientation.

IP20 with conductors connected — fine inside a closed panel, not for wet or washdown zones.

Listed as current production — no phase-out notice on record. The 5SY6 platform is Siemens' standard modular MCB line for industrial and commercial distribution. If you're filling a BOM line or swapping a failed unit, this order code is the direct replacement for any earlier 5SY6 variant with the same rating and curve.
