Description
Crafted for commercial maintenance, this 50-amp molded case breaker provides essential long-time and instantaneous protection. The two-pole device is engineered for facilities operating on older distribution equipment. Electricians rely on this bolt-on unit to service classic Westinghouse and Eaton panelboards. Matching the original E-Frame dimensions eliminates the need to retrofit panels for the newer EHD2050 substitute. Rated to interrupt 10kA at 240VAC, it includes load side lugs.Specifications

Product FAQs
6 answersIs the Westinghouse EB2050 obsolete, and what is the modern replacement?
Yes, the original Westinghouse EB-frame breakers are obsolete. The direct modern replacement is the Eaton EHD2050, which shares the same physical dimensions and bolt-on mounting configuration for seamless installation in existing panels.
Which panelboards are compatible with the EB2050 circuit breaker?
This bolt-on breaker is designed for use in classic Westinghouse and modern Eaton panelboards that accept E-Frame breakers. Always verify your specific panel's labeling to ensure E-Frame or EB-type breakers are listed as approved for use.
Can the EB2050 be used in direct current (DC) systems?
Yes, in addition to its 240VAC rating, this breaker is rated for DC applications. It provides an interrupting capacity of 5kAIC at 125/250VDC, making it suitable for specific DC control circuits.
Are the trip settings on the EB2050 adjustable for custom coordination?
No, this breaker features a non-interchangeable, fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory-set and cannot be adjusted in the field.
What type of wire can be used with the EB2050 load lugs?
The factory-installed load lugs accept both copper (Cu) and aluminum (Al) conductors ranging from 14 AWG up to 1/0 AWG. Ensure you apply the correct torque as specified on the breaker's faceplate during installation to prevent thermal issues.
How does the EB2050 connect to the panelboard bus?
It utilizes a bolt-on connection type, which provides a secure, mechanically fastened connection to the panel bus. This design is standard for commercial and industrial distribution equipment to ensure a reliable connection and prevent arcing.
