What it is and where it fits
The Siemens 5SM6014-2 is a SENTRON arc-fault detection device (AFDD) block — not a standalone breaker, but a detection module designed to snap onto a 5SY60 miniature circuit breaker (MCB) or RCBO, forming a combined 1P+N arc-fault protective unit. It occupies a single modular width (36 mm) on a DIN rail and is rated for 1-40 A at 230 V AC, 50 Hz, making it the go-to component for residential and light-commercial final circuits where series and parallel arc faults need to be caught before they escalate into a fire.
Deployment context and IP rating
The block mounts in any position on a standard DIN rail (REG) and carries IP20 protection with the connected protective device and conductors in place — meaning it's intended for use inside a distribution board or enclosure, not in wet or dusty environments. The 70 mm installation depth (68.5 mm body depth) fits standard shallow enclosures.
Environmental and mechanical specs
Halogen-free and silicon-free construction, rated for ambient temperatures from -40 °C to 75 °C (with 95% RH up to 55 °C). Mechanical service life is 10,000 operating cycles typical. Overvoltage category III, pollution degree 2 — standard for fixed-installation final circuits.
