CJ40-160~250A/4

CJ40 series AC contactor (hereinafter referred to as the contactor) is mainly used for AC 50 Hz or 60 Hz, rated voltage 660V or 1140V, current 1000A circuit connected with the breaker in the power system, and with the appropriate thermal relay or electronic protection device combination into motor starter, in order to protect the possible overload circuits. Standard: GB, IEC 60947-4-14048.4 1.

The normal working conditions and installation conditions

·  ambient air temperature is: - 5 ℃ + 40 ℃, its average no more than 35 ℃ + within 24 hours.

· Altitude: not more than 2000 m.

· Atmospheric conditions: + 40 ℃, the highest temperature of air relative humidity no more than 50%; At low temperature can be allowed to have a higher relative humidity,For example, 90% at 20 ℃. Due to temperature change occasionally produce condensation special measures should be taken.

· Pollution levels: level 3.

· Install categories: Ⅲ class.

· Installed condition: surface and vertical gradient is not more than + / - 5 °

· Impact vibration: the product should be installed and used in no significant shake, impact and vibration.

· Contactor is straight moving type structure, contact arc extinguishing system is located in the upper, the electromagnetic system is located in the lower part, contact for the breakpoints, made of silver. 63A and above products have six of auxiliary contacts, three kinds of combination.

· CJ40-63A product arcing cover the arc resistance of the plastic and iron gate, on the one hand, overcomes the drawback of clay arcing cover fragile, on the other hand has the advantages of high breaking capacity, high reliability.

· Action condition: and voltage (85% ~ 110%) Us; Release voltage: normal (20% ~ 75%) for Us, 

     the rest for Us (10% ~ 75%)

· Us for coil control supply voltage: AC 50 Hz, 110V, 127V, 220V, 380V; DC 110V, 220V.

· Mechanical life: less than 250A 10 million times, 315~500A 6 million times, 630~1000A 3 million times.
