A) Eight-hour working system: This working system is the basic working system. The agreed free air heating current Ith of the Modular Contactor is determined by this working system.
B) Intermittent periodic working system: The operating frequency of the AC contactor is 30 times/h and the load factor is 40%.
Action (operation) condition
In the ambient air temperature range of - 5 +60℃, when the suction coil of the contactor is applied with a quota to control the power supply voltage Us so as to heat it to a stable state, the contactor should be reliably closed at any voltage in the range of (85%~110%) Us, and released and disconnected between 75% and 20% of the rated control power supply voltage Us.
Product life
Mechanical life: The mechanical life of modular contactor is not less than 1 million times.
Electrical life: The electrical life of analog contactor is not less than 100,000 times.
