What this SENTRON AFDD-MCB combination does
The Siemens 5SV6016-7MC16 is a compact SENTRON AFDD-MCB combination — an arc-fault detection device and miniature circuit breaker in one 18 mm wide unit. It protects a 1P+N final circuit against arc faults, overload, and short-circuit, with a C-curve trip characteristic and 6 kA breaking capacity per EN 60898-1 at 230 V AC. The built-in metering measures voltage, current, active/reactive/apparent power, line frequency, power factor, temperature, switching cycles, operating hours, and trip events, displayed on the front panel. The unit snaps onto a DIN rail (REG) and occupies one modular width (18 mm), with a depth of 68.5 mm and height of 90 mm. It can be mounted in any position. Rear-side protection is IP20; the front face is IP40. The design is halogen-free and silicon-free, and it meets IEC 61373 for shock and vibration resistance — relevant for rail or mobile applications.
Metering accuracy and standards
The metering function is seamless (continuous) and complies with IEC 61557-12, IEC 62053-22, and IEC 62053-23 for error limits. Voltage and current accuracy is 0.5 %; active power accuracy is 1 %. The unit also includes a frequency meter, ammeter, voltmeter, wattmeter, and reactive power meter — all integrated into the 1-MW footprint, eliminating the need for a separate panel meter on that circuit.
Panel integration and environment
Rated for overvoltage category III and pollution degree 2, the 5SV6016-7MC16 is suited for fixed-installation distribution panels. The operating temperature range spans -40 °C to 75 °C, and the unit supports a wireless protocol for data communication — useful for remote monitoring or integration with building management systems.
