Scope
JB/T 11153-2011 is the English-translated version of 单极和双极交流接触器.
JB/T 11153-2011 is a recommended Chinese machinery industry standard for single-pole and double-pole alternating current contactors.
It gives the general rules and requirements for these devices, including terms and definitions, symbols, classification, characteristics, product information, normal conditions of use, installation and transport, structural and performance requirements, and tests.
The standard applies to contactors used on AC at 50 Hz or 60 Hz whose main contacts have a rated voltage of no more than 220 V, in utilisation category AC-8a or AC-8b at a rated working voltage of 220 V and a rated operating current of no more than 63 A, for remote making and breaking of single-phase circuits.
It states that such contactors are generally not intended to break short-circuit currents, so suitable short-circuit protection has to be installed.
