Product FAQs
6 answersWhat is required to make the LA3400PRF frame operational?
Because this is a frame-only component, you must install a compatible Eaton or Westinghouse LA-frame interchangeable thermal-magnetic trip unit to complete the circuit breaker and provide overcurrent protection.
Are Eaton and Cutler-Hammer trip units compatible with this Westinghouse frame?
Yes. Since Eaton acquired the Westinghouse electrical distribution division, Eaton and Cutler-Hammer LA-frame trip units and internal accessories are fully interchangeable with this Westinghouse frame.
Can the LA3400PRF be used in direct current applications?
Yes, in addition to its standard alternating current ratings, this LA-frame breaker is rated for use in DC electrical systems up to 250V DC.
What safety standards does the LA3400PRF meet?
This molded case circuit breaker frame is UL 489 listed, ensuring it meets the required safety and performance standards for commercial and industrial electrical distribution equipment.
What types of internal accessories can be installed in this frame?
The LA3400PRF supports standard TRI-PAC LA-frame accessories, including motor operators, undervoltage releases, and auxiliary switches for advanced control and monitoring.
What are the installation benefits of the bolt-on connection?
The bolt-on design provides a rigid, vibration-resistant mechanical and electrical connection to the panelboard bus, which reduces the risk of loose connections in heavy commercial or industrial environments.
