How it protects your electrical system

The LDC3300 combines a thermal element and a magnetic mechanism to address both overloads and short circuits. The thermal component responds to sustained overcurrent by heating a bi-metallic strip, while the magnetic part rapidly trips during a high-current fault. This dual-action design delivers predictable trip characteristics, helping prevent insulation damage and keeping downstream equipment safeguarded.

Practical applications and tips

• Ideal for retrofits or new installations where OEM compatibility is essential, ensuring plug-and-play replacement in compatible panelboards and loadcenters.
• Choose for three-phase feeders or systems that require balanced protection across all legs, reducing the risk of uneven loading and potential faults.
• When replacing an existing breaker, verify that your panel accepts thermal-magnetic molded case breakers and ensure the LDC3300’s rating aligns with the circuit’s protection needs as indicated on the panel labeling.

With the Eaton LDC3300, you gain a compact, reliable solution that guards wiring and equipment while maximizing panel space. Whether upgrading an existing panel or wiring a new installation, this 3-pole, 600 V molded case circuit breaker delivers consistent protection and straightforward installation through the AmpState catalog.
