Magnetic Contactors (MC) Durability of Operational Environment Stress Classifications

Magnetic Contactors (MC) Durability of Operational Environment Stress Classifications

DURABILITY TO STANDARD: 

Switching durability(endurance) is classified for the standardization between each manufacturer about contact point by consumption of magnetic contactor, switch when on/off action and on/off durability of device.

(1) Mechanical switching durability(endurance) and electrical switching

durability(endurance)

There are mechanical durability and electrical durability in switching durability(endurance)

of the magnetic contactor, each one is classified by series from 0 to 6 with corresponding to its characteristic.

(2) Indication method of durability(performance)

a) Mechanical switching durability(endurance)

It is switching durability by mechanical consumption when it is switching under standard

conditions without flowing current to the main circuit.

b) Electrical switching durability (endurance)

It is switching durability by electrical consumption when it is switching under standard

conditions with flowing current to the main circuit.
