The Siemens 5SV6016-6MC16 is a SENTRON AFDD-MCB combination — a single compact unit that packs arc-fault detection, overcurrent protection, and energy metering into one 18 mm-wide module (one modular width). It protects a 1P+N circuit with a B tripping characteristic and a 6 000 A breaking capacity per EN 60898-1, meaning it clears short-circuit faults up to 6 kA at 230 V AC without needing an upstream fuse backup in most residential or light-commercial panels.
Integrated metering — what you can read off the front
Unlike a plain MCB, this unit includes a voltmeter, ammeter, wattmeter, frequency meter, and reactive-power meter — all visible on the front display. Accuracy for current and voltage is 0.5 %, for active power 1 %, per IEC 61557-12, IEC 62053-22, and IEC 62053-23. The display cycles through voltage, current, active/apparent/reactive power, active energy, line frequency, power factor, temperature, switching cycles, operating hours, tripping events, and warnings — enough data to trend a circuit's health without a separate power meter.
Where it fits — panel integration and environment
Depth is 68.5 mm, installation depth 70 mm — it clears most shallow enclosures. Rated IP40 on the front, IP20 at the rear (with conductors and protective device connected).
Compliance and ruggedness notes
Tested for shock and vibration per IEC 61373, so it holds up in rail-vehicle or mobile-equipment panels. Supports a wireless protocol for data readout — no separate communication module needed to pull metering data off the unit.
