Eaton/Cutler-Hammer HKDDC3400A1301S5001Z01 Circuit Breaker

No. The Z01 suffix in the catalog number indicates this breaker is supplied without standard line and load lugs. Installers must source the appropriate terminal hardware separately based on their specific wire size and application requirements.

While the standard K-Frame lugs accept either two 3/0 AWG to 250 kcmil or one 3/0 AWG to 500 kcmil conductors, this specific Z01 variant is supplied without lugs. You must select and install terminal hardware that matches your required wire gauge and material.

The built-in 48VDC shunt trip allows for remote opening of the breaker via an external control signal. The 2A/2B auxiliary switch provides two normally open and two normally closed contacts for remote status monitoring and signaling.

For DC applications, multiple poles are typically connected in series to achieve the maximum voltage and interruption ratings. Always refer to Eaton installation instructions for the correct wiring configuration based on whether your system is grounded or ungrounded.

In the Eaton Series C nomenclature, the A13 suffix designates a factory-installed 2A/2B auxiliary switch. The S50 suffix indicates a factory-installed shunt trip, which is configured for 48VDC on this specific model.

In the event of a thermal overload trip, the thermal-magnetic trip unit must cool down before the circuit breaker can be reset. Always investigate and resolve the cause of the fault before reclosing the breaker.

You can use the push-to-trip button located on the front of the breaker to mechanically trip the unit. This checks the tripping function and should be used periodically to exercise the operating mechanism.
