Relays complying with IEC standards

What’s IEC? IEC shorts for The International Electrotechnical Commission, it was established in 1906. It is the world's earliest established international electrotechnical standardization organization, responsible for international standardization in the fields of electrical engineering and electronic engineering.

IEC standards are divided into the following 8 categories:

First category

(Basic standard): terminology, measurement unit and its letter symbols, graphic symbols, line end marks, standard voltage, current rating and frequency, insulation coordination, insulation structure, environmental testing, classification of environmental conditions, reliability and maintenance Sex.

Second category

(Raw material standards): Working fluids for electrical instruments, insulating materials, measuring methods for electrical characteristics of metal materials, magnetic alloys and magnetic steel, bare aluminum conductors.

Third category

(General safety, installation and operation standards): Electrical installations under severe outdoor conditions on buildings and ships, electrical appliances in explosive gases, electrical equipment in industrial machinery, protection of enclosures, live working tools, lighting protection devices, laser equipment .

Fourth category

(Measurement, control and general test standards): Electric energy measurement and load control equipment, electronic technology and basic electricity measurement equipment, industrial process measurement and control, nuclear instruments, instrument transformers, high-voltage test devices and technology.

The fifth category

(Standards for the generation and utilization of electricity): rotating electrical machines, water turbines, steam turbines, power transformers, power electronics, power capacitors, primary cells and battery packs, power relays, short-circuit currents, solar photovoltaic systems, electrical traction equipment, electric welding, electric heating equipment , Electric cars and trucks.

Sixth category

(Standards for power transmission and distribution): switchgear and control equipment, wires, low-voltage fuses and high-voltage fuses, surge arresters, power system remote control, remote protection and communication equipment, overhead lines.

Seventh category

(Telecommunication and electronic components and component standards): semiconductor devices and integrated circuits, printed circuits, capacitors and resistors, micro fuses, electronic tubes, relays, fiber optics, cables, wires and waveguides, electromechanical components, piezoelectric components, magnetics Components and ferrite materials.

Eighth category

(Telecommunications, electronic systems and equipment and information technology standards): radio communications, information technology equipment, data processing equipment and office machinery safety, audio and video system equipment, medical electrical equipment, digital data communications for measurement and control systems, remote control and Remote protection, electromagnetic compatibility, measurement, limitation and suppression of radio interference; alarm system; navigation instrument.

IVY attaches great importance to the IEC standards, so our meters are strictly in accordance with the IEC standards, especially most IVY relays comply with the IEC62055-31 UC2 UC3 certification verified by the TUV laboratory, you may be interested in us.
