Rated power:
1) 8-hour service.
This is the basic task, and the conventional heating current Ith of the contactor is determined by this working system2) Intermittent periodic service
The rated operating frequency of the contactor under this operating condition is 30 times/h and the load factor is 40%.
Action (process) condition:
If the ambient temperature is in the range of -5 °C to +60 °C, apply the control current supply voltage Us to the suction coil of the contactor so that it heats up in a steady state. Then the contactor should be reliably closed under any voltage by (85% ~ 110%) us. Its trigger voltage is (20% ~ 75%) US.
Package list:
1 x AC contactor.
