( Brand: Ge ), ( Part Type: Starter ), ( Manufacturer Part Number: CR408B694R31DAJJA )
The General Electric (GE) CR408B694R31DAJJA Magnetic Starter is a versatile and reliable electromechanical device designed to control and protect inductive loads, such as motors and compressors, in industrial and commercial applications. This magnetic starter from GE's industrial solutions portfolio is a combination type, which means it integrates both magnetic contactors and overload relays in a single housing.
The magnetic contactors in this starter are designed to handle inductive loads up to 400 volts and 60 amps. They feature gold-plated contacts, ensuring excellent electrical conductivity and long-term reliability. The contactors are mechanically operated by a set of magnetic latching plungers, which are actuated by the applied current to the coils. This design offers several advantages, including faster making and breaking times, reduced wear and tear, and improved safety.
The overload relays in the GE CR408B694R31DAJJA Magnetic Starter are designed to protect the motor or compressor from overloading, which can lead to overheating, premature failure, or even fire hazards. They are thermally operated, meaning they respond to the heat generated by the motor or compressor, and they come with adjustable trip settings to cater to various application requirements.
This magnetic starter also features a number of other useful features, such as:* A lockout/tagout system for safety during maintenance and repairs
* A manual restart button for manually restarting the motor or compressor in case of a tripped overload relay
* A built-in current transformer for monitoring the load current
* A clear and conveniently located indicator lamp for visual confirmation of the starter status
The housing of the GE CR408B694R31DAJJA Magnetic Starter is robust and rugged, designed to withstand harsh industrial environments. It is constructed from die-cast aluminum and features an IP20 degree of protection, which means it is protected against dust and dripping water from all directions. The starter is also UL listed, ensuring compliance with various safety and performance standards.
The GE CR408B694R31DAJJA Magnetic Starter is easy to install and operate, with clear markings and accessible terminals. It comes with mounting holes and can be mounted on a DIN rail or on the wall using the provided mounting brackets. The starter also comes with a comprehensive instruction manual and wiring diagrams to facilitate easy installation and setup.
In summary, the General Electric CR408B694R31DAJJA Magnetic Starter is a robust and reliable electromechanical device designed to control and protect inductive loads in industrial and commercial applications. Its combination of magnetic contactors and overload relays, along with its numerous features and easy installation, make it an excellent choice for applications that require safe, efficient, and cost-effective motor or compressor control.
