What is internal arc classification?
The definition of internal arc classes (IAC) describes mainly the types of accessibility, test arrangement, test procedure and acceptance criteria. The types of accessibility A and B (for authorised personnel only and general public, respectively) are extended to type C for pole mounted metal enclosed switchgear.

What IEC 61439?
IEC 61439 defines which points the manufacturer and the user of a switchgear and controlgear assembly have to define. The switchgear and controlgear assembly is viewed as a so-called black box, whose interfaces to the environment are defined in 4 areas.
What is a BS 60947-2?
BS EN 60947-2 (EN 60947-2, IEC 60947-2) relate to low-voltage circuit-breakers for use in industrial and similar installations. In the UK these are traditionally known as moulded case circuit-breakers (MCCB’s) or air circuit-breakers (ACB’s) according to the construction.
What is the difference between switchgear and controlgear?
Switchgear consists of switch disconnectors, fused Switches, switch fuses, isolators, while controlgear consists of DOL/Star,delta contactors, time clock/switches, relays, overload, stop buttons, PLCs. As professional switchgear supplier we can provide our clients high quality switchgear.
What is IEC circuit breaker?
IEC 60947-2 governs circuit breakers (CBs) for industrial applications. They protect electrical power distribution of up to 1000 volts a.c. and 1500 volts d.c. with an entire spectrum of rated currents from 0,5 to 6300A.
What is the IEC standard for HV breaker?
IEC standard high voltage circuit-breakers: Practical guidelines for overvoltage protection in generator applications. Abstract: The IEEE C37. 013, [1] standard defines the overvoltage withstand requirements for circuit breakers (CBs) intended for use in generator applications.
What is AFL and AFLR?
A-F, A-FL and A-FLR are defined in IEC 62217-200 and help to define internal arc performance of medium voltage or high voltage switchgear. The following definitions are described as: – A-F front protection only for users. A-FL front and side protection for users. A-FLR all sided protection for users.
What is internal arc fault?
An internal arc fault is one that occurs inside switchgear. The internal arc resistance of switchgear denotes its ability to withstand arc faults. And, should an arc fault occur, to contain it within a single compartment in the cubicle and divert the hot gases away from personnel.
Is standard for VCB?
The IEC 62271 series consists of the IEC 62271- 100, which is the standard for the main body of the VCB, and the IEC 62271-200, which is the standard for the switchgear in which the VCB is housed.
What is the difference between 60439 and 61439?
IEC 61439-5 will replace IEC 60439-5 (still valid) The new IEC 61439 standard applies to enclosures for which the rated voltage is under 1000 V AC (at frequencies not exceeding 1000 Hz) or 1500 V DC. The standard defines the design verified ASSEMBLIES and eliminates completely the categories TTA and PTTA.
Is IEC 60439 obsolete?
After 5 years of transition period International Electrotechnical Commission has made the IEC-60439 obsolete but IS-8623 is still in use. The latest IEC has forbidden the PTTA & TTA concept of assemblies and put a new concept verified assemblies.
What is a BS 60947 3?
IEC 60947-3:2020 applies to switches, disconnectors, switch-disconnectors and fuse-combination units and their dedicated accessories to be used in distribution circuits and motor circuits of which the rated voltage does not exceed 1 000 V AC or 1 500 V DC.
What is the difference between RMU and switchgear?
