Description
Built for industrial power distribution, the Eaton L3500 is a 500A, 3-pole molded case circuit breaker. It utilizes a thermal-magnetic trip mechanism with adjustable magnetic settings for accurate protection. This unit-mount breaker integrates into Westinghouse and Cutler-Hammer panelboards and is a cross-reference for the LD3500. Delivering a 42kAIC capacity at 240VAC, the L-Series breaker includes factory-installed line and load lugs.Specifications

Product FAQs
5 answersCan I use the Eaton Series C LD3500 to replace a legacy L3500?
Yes, the LD3500 is the direct Series C replacement for the legacy Westinghouse and Cutler-Hammer L3500. While the LD3500 offers higher interrupting capacities, it shares the same physical L-frame footprint for retrofitting into existing panelboards and switchboards.
What type of equipment is the L3500 compatible with?
This unit-mount breaker is engineered for legacy power distribution systems. It integrates directly into older Westinghouse and Cutler-Hammer panelboards, switchboards, and motor control centers that require a standard L-frame footprint.
Are line and load lugs included with the L3500?
Yes, this breaker includes factory-installed lugs on both the line and load sides. The terminals are rated to accept two 250 to 500 kcmil aluminum or copper conductors per phase.
How does the trip unit on the L3500 operate?
It utilizes a thermal-magnetic trip mechanism with LI (Long-Time and Instantaneous) functions. The thermal element provides fixed overload protection, while the magnetic instantaneous trip can be adjusted in the field to coordinate with specific fault current requirements.
Is the L3500 suitable for direct current applications?
Yes, in addition to its AC ratings, the L3500 is rated for up to 250VDC with an interrupting capacity of 10 kAIC. This makes it suitable for specific industrial DC control and distribution circuits.
