- Scope
- This standard specifies the product classification, basic parameters, requirements, instructions for use, test methods, inspection rules, marking, packaging, transportation, storage, etc. of explosion-proof operating columns. This standard applies to the design, manufacture and inspection of explosion-proof and anti-corrosion-proof operating columns with a rated working voltage of 380V and below. The operating column is mainly used in factories with explosive gas environments or corrosive gas environments around them to operate electromagnetic appliances at long distances, or to control on, off, and conversion of signals and control circuits. It can also be used to control on-site or indirectly near the controlled motor. The motor starts, stops and reverses; the operating column equipped with ammeter and signal light can also monitor and display the motor operation or circuit conditions.
