Material Compliance and Certifications
The JT3100T is UL Listed. For additional compliance information, contact the manufacturer. No other material-compliance certifications were included in the supplied product data, so they should not be assumed.
Where It Works Best
The JT3100T is intended for compatible Eaton Series C molded-case circuit breaker assemblies that require a 100A, three-pole thermal-magnetic trip unit with the T185 trip type, JT breaker type, and J-K frame size. That makes it particularly relevant when maintaining existing or legacy equipment, where the original electrical and physical configuration must be preserved.
Before installation, compare the JT3100T catalog number, 100A rating, three-pole configuration, T185 trip type, JT breaker type, J-K frame designation, and dimensions with the existing assembly. Checking those details together is a much better way to establish form, fit, and functional compatibility than relying on amperage alone.
