Noark Ex9CS 12 A Miniature Contactor

Ex9C contactors have a robust design and construction intended for various applications including heavy industrial applications. Splitting into various frame sizes brings optimization of electrical parameters and mechanical dimensions. Frame sizes include: 6~12A (miniature), 9~38A, 40~100A, 115~500A. All these frame sizes share accessory auxiliary contacts. Overload relays differ with the frame sizes in order to fit respective contactor of given rated current.

Product features include:

· Contactors according to IEC/EN 60947-4-1, IEC/EN 60947-4-1, UL 60947-1 and UL 60947-4-1

· Rated current from 6~12 A.

· Built-in auxiliary contacts; additional auxiliary contacts are front mounted.

NOARK Ex9RD 11.5 A Thermal Overolad Relay

Thermal overload relays are economic electromechanical protection devices for the main circuit. They are used mainly to protect motors against overload and phase failures. Starter combinations are setup together with contactors.
The overload relays have a setting scale in Amperes, which allows the direct adjusting of the relay without any additional calculation. In compliance with international and national standards, the setting current is the rated current of the motor and not the tripping current (no tripping at 1.05 x I, tripping at 1.2 x I; I = setting current). The relays are constructed to protect themselves in the event of an overload. The overload relay has to be protected against short-circuit. The appropriate short-circuit protection devices are shown in the table..

Product features include:

· Rated current from 6~12 A @ 600 Vac, 50/60 Hz.

· ROverload protection trip Class 10 A.

· Phase loss sensitivity.

· Temperature compensation from -13 to 131 F (-25 to +55 C).

· Adjustable current setting for overload protection.

· Automatic or manual reset selectable.

· Trip-free mechanism.

· Status indication.

· STOP and TEST function.

· Direct mount to contactors or 35 mm DIN rail mounting base option.
