CLD3600 - 600Amp Circuit Breaker

CLD3600 - 600Amp Circuit Breaker

The CLD3600 Eaton LD frame circuit breaker is a 600 Amp, 3-pole molded case circuit breaker used in commercial and industrial power distribution systems where larger electrical loads need dependable circuit protection. In everyday terms, this is the kind of breaker you’ll find in main service sections and feeder applications inside switchboards or panelboards that are already built around Eaton LD equipment.

In the field, the CLD3600 is usually part of existing infrastructure rather than a redesign. It’s commonly used when maintaining or replacing breakers in systems already in service, where preserving the original equipment layout matters. Because it belongs to the Eaton LD family, it fits into compatible assemblies without requiring changes to the panel design, which makes it practical for service work and system upkeep.

With interrupting ratings of 65kA at 240VAC, 35kA at 480VAC, and 25kA at 600VAC, the CLD3600 is built for systems where available fault current has to be properly accounted for. The 3-pole design ensures all phases open together, which is standard for three-phase distribution and helps maintain consistent system behavior during fault conditions.
