It occupies 2 modular width units (36 mm) on a DIN rail and is designated for retail-line branch circuit protection. The B curve trips between 3–5× rated current, making it a fit for resistive or general-purpose loads where inrush is minimal — think lighting circuits or small control transformers in a retail environment. ## Key ratings and what they mean for fit The 6 kA breaking capacity at 415 V AC per EN 60898 is the standard residential/commercial fault-interruption rating — adequate for most panelboards fed by a distribution transformer with typical available fault current under 6 kA. The 6 A continuous rating at 30 °C derates in higher ambient temperatures; the part is rated for operation from -40 °C to 75 °C, covering unheated enclosures and rooftop gear. Rated for 250 V AC single-phase and 440 V AC multi-phase operation, the 2-pole configuration handles split-phase or two-leg circuits. DC rating extends to 72 V, useful for control power or battery-backed loads. Overvoltage category III and pollution degree 2 suit fixed-installation panels in dry, non-conductive environments. Mechanical service life is 10,000 switching cycles typical. The breaker is halogen-free and silicon-free, and is sealable for tamper-proof installations. ## Mounting and integration Snap-on mounting to 35 mm DIN rail per EN 60715. Any mounting position is permitted. Installation depth is 70 mm behind the panel face; overall depth is 76 mm including the toggle. The IP20 rating with connected conductors means the busbar stabs and terminals are finger-safe only when wired — standard for distribution board use. Width of 36 mm (2 MW) fits standard modular enclosure cutouts.","metaTitle":"Siemens 5SJ6206-6RC SENTRON MCB, 2P, 6A, B Curve, 6kA","metaDescription":"Siemens SENTRON 5SJ6206-6RC miniature circuit breaker, 2-pole, 6 A, B characteristic, 6 kA breaking capacity per EN 60898.
