FLAIR 23DM is an intelligent voltage monitoring device developed by Schneider Electric for medium voltage gas insulated ring main units (RMU, model SM6/RM6). It integrates three-phase voltage measurement, grid fault alarm, live-line detection and remote Modbus communication. It can be matched with VPIS-V0 voltage presence indicators and EMS58423 connecting cables as a complete set, widely used in distribution switching stations and outdoor RMU cabinets.

Surge Protective Device (SPD), also known as lightning arrester, is an electronic safety apparatus designed to safeguard various electronic equipment, instruments, meters and communication lines. When external interference induces sudden peak currents or voltages in electrical circuits or communication lines, the SPD will conduct and divert surge currents within an extremely short time, preventing surges from damaging other equipment on the circuit. This SPD is applicable to AC power supply systems with a frequency of 50/60 Hz and a rated voltage of 220 V / 380 V. It provides protection against electrical surges caused by direct and indirect lightning strikes or other transient overvoltages, and meets surge protection demands for residential buildings, the tertiary industry and industrial sectors.

HYM1 series molded case circuit breaker (hereinafter referred to as circuit breaker) is suitable for distributing network of AC 50Hz (or 60Hz), rated insulation voltage 690V, rated working voltage 690V or below and rated current 1250A or below. It can be used to distribute electric energy and protect the circuit and electric equipment against overload, short circuit and under voltage, furthermore, the circuit breakers of frame size 400A below also can protect the motor against overload, under voltage and short circuit. Under normal condition, the circuit breaker also can be used to switch the circuit and start the motor infrequently. The products are in conformity with such standards as IEC 60947-2 and GB 14048.2.

Reactors, also known as inductors, are widely used in circuits. Due to the electromagnetic induction effect, there is a certain degree of inductance in the circuit, which can prevent changes in current. When a conductor is energized, it will generate a magnetic field within a certain spatial range it occupies, so all conductors that can carry current have a general sense of inductance. However, the inductance of an electrified long straight conductor is relatively small, and the magnetic field generated is not strong. Therefore, the actual reactor is a hollow core reactor in which the wire is wound into a solenoid form; Sometimes, in order to increase the inductance of this solenoid, an iron core is inserted into the solenoid, known as an iron core reactor. Reactance is divided into inductive reactance and capacitive reactance. A more scientific classification is that inductive reactance (inductor) and capacitive reactance (capacitor) are collectively referred to as reactors. However, due to the existence of inductors in the past, which were called reactors, capacitors are now referred to as capacitive reactance, while reactors specifically refer to inductors.
