Sinotimer AFDD2-63 B10 is a 1P+N AFDD protection device designed to protect single-phase circuits from various types of electrical faults.

It combines arc fault detection (AFDD), residual current protection, overload protection, and short-circuit protection in a single device. Arc fault detection helps reduce the risk of fire caused by faulty contacts, damaged conductors, or other faults that can produce electrical arcs.

The model offered features a Type B trip curve, a rated current of 10 A, and a residual current sensitivity of 30 mA.

Built-in Protection Functions

• AF – Arc fault: detects characteristic arc fault current signals and interrupts the circuit.
• GF – Ground fault / leakage current: 30 mA residual current protection, Type AC.
• Overload: disconnects the power supply when the current exceeds the B10 trip curve characteristics.
• Short circuit: provides tripping at high fault currents, with a rated breaking capacity of 4.5 kA.

Front Panel Features

The device features an ON/OFF lever, an orange TEST button, a blue reset button, and three LED indicators:

• RUN – green: operating status;
• GF – red: fault indication;
• AF – yellow: arc fault detection indication.

The mechanical indicator provides an additional visual status: green – normal status, red – fault status.

Installation

The device is designed for mounting on a 35 mm DIN rail inside an electrical panel. As a 1P+N device, the phase and neutral must be connected according to the diagram and markings on the device. Installation should be carried out by qualified personnel with the circuit power supply switched off. The AFDD rated current should be selected according to the circuit, conductor cross-section, installation method, and electrical installation requirements.

Important: For the rating shown in the images, the characteristic is B10 = 10 A. The manufacturer's table also lists other current ratings in the AFDD2-63 series, but these do not represent the specifications of this B10 model.
