Eaton WMZT3DX0 Three-Phase Molded Case Circuit Breaker

The Eaton WMZT3DX0 is a three-pole molded-case circuit breaker rated for 10 kAIC at 480/277V. It features a D Curve trip characteristic and is identified by the WMZT3DX0 part number. This device provides overcurrent protection for three-phase circuits operating at 480/277V, helping to limit fault currents and protect downstream equipment. With molded-case construction, it is designed for integration into electrical distribution assemblies where compact form factor and reliable interrupting performance at higher voltages are required. The combination of three poles and the 10 kAIC rating specifies the maximum fault current the breaker can interrupt safely under the stated voltage conditions. Always verify compatibility with your specific panel or enclosure and confirm that the 480/277V rating and D Curve behavior meet your protection requirements.
