CLD3600 - 600Amp Circuit Breaker

CLD3600 - 600 Amp Circuit Breaker

The CLD3600 circuit breaker is a high-capacity 600 amp, 3-pole thermal-magnetic circuit breaker designed to provide dependable overcurrent and short-circuit protection in demanding commercial and industrial electrical systems. Built on the LD frame platform, this breaker features an interchangeable trip unit, allowing flexibility in maintenance and system configuration while maintaining precise protection performance. With strong interrupting ratings of 25kA at 600VAC, 35kA at 480VAC, and 65kA at 240VAC, the CLD3600 helps safeguard electrical distribution equipment from damaging fault currents.

Rated for 100 percent continuous operation at 40°C, this breaker is engineered for applications where circuits may carry their full rated load without derating. Its thermal-magnetic trip mechanism delivers reliable long-time and instantaneous protection, helping prevent overheating and electrical faults before they can escalate. The unit also carries an HACR rating, making it suitable for heating, air-conditioning, and refrigeration systems often found in commercial facilities. With included load terminals and a durable build designed for large-capacity panels and switchgear, the CLD3600 provides dependable protection where consistent power distribution is critical.
