CAL18-11 ABB Coil Contactor

Review ABB Rc5-2/250 230v Coil Contactor Used

The ABB Cal18-11 A145-30 RC5-2 250V Coil Contactors, manufactured by ABB (Asea Brown Boveri), are electromechanical devices designed for controlling loading equipment in various industrial applications. These contactors serve as the interface between electrical power sources and the electrical components or loads they power on and off.

This specific model, Cal18-11 A145-30 RC5-2, can handle a contact voltage of 250V. The contacts, identified by the RC5-2 suffix in the model number, are rated for a contact current of 145A and a contact resistance of no more than 5 milliohms at 25 C. The contactor comes with 18 poles, providing the capability to control multiple loads independently.

The Cal11-18 contactor is built with a metal-enclosed construction for improved reliability and safety. Its frame size, identified by the Cal prefix in the model number, is calculated based on the total current that the contactor can carry without causing a temperature rise above acceptable limits. In this case, it is a Cal18, capable of handling inrush currents up to 400A.

The make/break control action of this contactor is achieved through the use of a coil. This coil, which may need to be ordered separately depending on the specific application, powers a solenoid to mechanically open or close the contacts. The contactor can be controlled remotely via an auxiliary contact or pilot device.

This contactor meets various industry standards, including CE and IEC. It is designed to operate in harsh industrial environments with an Operating temperature range of -25 C to 40 C and a Storage temperature range of -50 C to 60 C. The contactor's accessories include terminal blocks, plugs, and pilot contacts compatible with different applications and customer preferences.

With its robust, reliable design and broad application compatibility, the ABB Cal18-11 A145-30 RC5-2 250V Coil Contactors provide reliable electrical switching for demanding industrial needs.

The ABb Cal18-11 A145-30 RC5-2 250V coil contactor is a type of electrical switching device used to control AC power circuits. This contactor comes with specifications that include a contact rating of Cal18-11 (11 contacts, each with a contact current capacity of 18A and a contact voltage of 250V), a coil rating of A145-30 (a coil voltage of 250V and a coil current of 145mA), and a frame size of RC5-2. Here are some potential pros and cons of purchasing this contactor:

1. High Contact Rating: This contactor can handle a high number of contacts, which could be ideal for applications that require multiple contact points.

2. Suitable for Industrial Applications: With its robust design, this contactor is well-suited for industrial environments where heavy loads and frequent switching may be required.

3. Universal Voltage and Frequency Compatibility: The contactor can be operated on voltages ranging from 200V to 250V and frequencies up to 60Hz, making it suitable for use in a variety of applications and regions.

4. Excellent Contactor Controllability: The contactor can be easily controlled using an external coil, providing precise control over the switching of the electrical load.

1. Higher Cost: Compared to single-pole contactors, multi-contact contactors like the Cal18-11 A145-30 RC5-2 250V contactor tend to be more expensive due to their greater complexity and higher contact capacity.

2. Increased Power Consumption: Due to the need for an external coil to control the contactor, there is a small amount of power consumption when the contactor is in the on or off position. This additional power consumption may be a consideration for applications where energy savings are a priority.

The ABb Cal18-11 A145-30 RC5-2 250V contactor offers a high contact rating, making it an excellent choice for applications that require multiple contact points. Its robust design, universal voltage and frequency compatibility, and excellent controllability make it well-suited for industrial environments. However, its higher cost and increased power consumption may be drawbacks for some users. Ultimately, the decision to purchase this contactor will depend on the specific requirements of the application and the priorities of the user.

If you require a contactor with multiple contact points and have applications that can accommodate the added cost and power consumption, the ABb Cal18-11 A145-30 RC5-2 250V contactor is a reliable and robust solution for industrial power switching applications. However, if you have simpler power switching needs, a single-pole contactor may be a more cost-effective option.
