CJ40-400 AC Contactor 500A Three Phase Electrical Contactor 3 Poles
Magnetic Contactor
Product Description:
CJ40 Series AC Contactors are primarily used in AC circuits at 50
Hz or 60 Hz, with a rated voltage up to 660 V or 1140 V and a
current up to 1000 A. They are designed for switching and
disconnecting circuits and can be combined with an appropriate
thermal relay or an electronic protection device into a motor
starter, protecting circuits that may be overloaded. Meet the
standards: GB / T14048.4, IEC / EN 60947-4-1.
Product Feature:
The CJ40 series contactors have a direct-acting structure, with the
contact and arc extinguishing system located at the top and the
electromagnetic system at the bottom. The contact is double-break
and made of silver alloy. Products 63A and above come with six
pairs of auxiliary contacts in three different combinations. For
CJ40-63A and above, the arc chute is composed of arc-resistant
plastic and iron grid plates. This design overcomes the fragility
of ceramic arc chutes while offering the benefits of high breaking
capacity and high reliability.
