AC contactor, BCH8-40M 2P 40A 230V Household AC DIN rail mounting with manual control switch for domestic applications (2NO)

With a very long service life, the contactor can withstand 100,000 full-load cycles in the AC-7a load category. Super quiet, it eliminates the obvious impact noise of traditional contactors upon activation and the low-frequency hum during operation. Very energy-efficient, in operation, the contactor requires a long power supply to keep the coil closed, which necessitates a large amount of electrical energy. This contactor significantly reduces the required power. Superior insulating material is used to greatly enhance operational safety. AC contactor 2 pole 40 amps 24v AC contactor coil 1 pole 30 amps AC Specification: Rated control supply voltage (Us): AC230V Rated current: 40A (AC-7a), 18A (AC-7b) Conventional thermal current (Ith): 63A Rated insulation voltage (Ui): 500 VAC Rated operating voltage (Ue): 250 VAC Number of contacts: 2NO, 2NC, 1NO - 1NC (optional) Maximum switching time: 30 times/hour Electrical life: 100,000 times Mechanical life: 1 million times Rated service: 1) 8-hour service This is the basic service, and the conventional heating current Ith of the contactor is determined by this working system. 2) Intermittent Periodic Duty: The nominal operating frequency of the contactor in this duty cycle is 30 times/hour and the load factor is 40%. Operating Condition: When the ambient temperature is between -5°C and -60°C, apply the nominal control supply voltage Us to the contactor's suction coil to heat it to a steady state. The contactor must close reliably under any voltage of (85% ~ 110%) Us. Its tripping voltage is (20% ~ 75%) Us.
