LDC3350L - 350 Amp Circuit Breaker

LDC3350L - 350 Amp Circuit Breaker

One detail makes the LDC3350L especially easy to distinguish when you’re checking a replacement: both line and load terminals are included. From there, the rest of the match comes down to the numbers and configuration already in your equipment. Rather than relying on the catalog number alone, compare the amperage, poles, LDC type, trip configuration, terminal arrangement, electrical ratings, and dimensions with the breaker already in service. When correctly matched, installed, and maintained within its stated ratings, the LDC3350L is built to last.

Key Features and Benefits

• Line and load terminals included: An important configuration detail to confirm when matching the LDC3350L with an existing installation.
• 350A current rating: Clearly identified for equipment requiring this exact amperage.
• Three-pole configuration: Provides the specified pole arrangement for compatible three-pole applications.
• Type LDC: A key identifier when replacing a Type LDC breaker in existing or legacy electrical equipment.
• Interchangeable trip unit: Part of the specified breaker configuration and worth checking against the device currently installed.

Material Compliance and Certifications

The supplied specifications identify the LDC3350L as HACR-rated. No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance information was provided for this exact part number.

Where a particular certification or material requirement applies, verify that requirement for the exact LDC3350L and the intended installation.

Where It Works Best

The LDC3350L 350A 3-pole circuit breaker is best suited to compatible existing and legacy electrical equipment that calls for a Type LDC thermal-magnetic breaker with an interchangeable trip unit and both line and load terminals. That terminal arrangement is worth noting—it’s one of the details that separates this configuration from similar breakers that may not be supplied the same way.
