The Siemens SENTRON 5SV6016-7MC25 is an AFDD-MCB combination unit — an arc-fault detection device and miniature circuit breaker in one compact 18 mm-wide housing. It occupies a single modular width on a DIN rail, rated for 230 V AC with a 6 kA breaking capacity per EN 60898-1. The 2-pole (1P+N) design with tripping characteristic C makes it suitable for final circuits where both overcurrent protection and series arc-fault detection are required in a single enclosure.
What the ratings mean for fit
The 6 kA breaking capacity at 230 V AC (EN 60898-1) covers most residential and light commercial final circuits — adequate for a standard distribution board where the prospective short-circuit current stays under that threshold. The C-curve trips between 5 and 10 times rated current, so it handles motor-starting inrush from small pumps or compressors without nuisance tripping. The 1 MW power measurement range (voltage, current, active/reactive/apparent power, frequency, power factor) is seamless and displayed on the front panel, with accuracy of 0.5 % for current and voltage, 1 % for active power — useful for submetering or energy monitoring without a separate meter.
Deployment context
Snaps onto a DIN rail (REG) and fits any mounting position. The 68.5 mm depth plus 70 mm installation depth means it sits flush in standard distribution boards. IP20 on the rear side, IP40 on the front — protected against tools and wires from the front, but not washdown-rated; keep it inside a panel. The operating temperature range from -40 °C to 75 °C covers unheated utility rooms and outdoor-adjacent enclosures. Halogen-free and silicon-free construction matters for sensitive environments like data centers or medical facilities where outgassing can damage contacts or optics.
