Description

Specification: Rated Control Supply Voltage (Us): AC 24V, AC 220V/230V(Optional) Rated Current: 20A(AC-7a), 7A(AC-7b) Conventional Thermal Current (lth): 25A Rated Insulation Voltage (Ui): 500VAC Rated Working Voltage (Ue): 400VAC Number of Poles: 4P(2NO + 2NC) Maximum Number of Switching Operations: 30times/hour Electrical Life: 100,000 times Mechanical Life: 1,000,000 times Package Weight: Approx. 219g Rated Duty: 1) 8-hour duty This is the basic duty, and conventional heating current Ith of the contactor is determined by this working system. 2) Intermittent periodic duty The rated operating frequency of the contactor under this duty is 30 times/h, and the load factor is 40%. Action(Operation) Condition: When the ambient temperature is in the range of -5°C to +60C, apply the rated control power supply voltage Us to the contactor sucking coil to make it heat up to a steady state, Then the contactor should be reliably closed under any voltage of (85% ~ 110%) Us. Its release voltage is (20%~75%) Us. Package list: 1 * AC Contactor
