LDC3350 - 350 Amp Circuit Breaker

LDC3350 - 350 Amp Circuit Breaker

With the LDC3350, it’s worth looking beyond the 350A rating. Put all of that together—the LDC type, amperage, poles, trip configuration, terminals, ratings, and footprint—and you have a much clearer way to judge form, fit, and functional compatibility. When correctly matched, installed, and maintained within its stated ratings, the LDC3350 is built to last.

Key Features and Benefits

• 350A, three-pole configuration: One of the first details to check when comparing the LDC3350 with the breaker being replaced.
• Type LDC: Helps narrow the match when the existing equipment calls for this specific breaker type.
• Interchangeable trip unit: An important part of the LDC3350 configuration and something that should be included in the compatibility check.
• Thermal-magnetic design: Matches applications requiring the specified thermal-magnetic breaker arrangement.
• Load terminals included: You know the supplied load-side connection arrangement before installation.
• 40°C rated: Another specification to compare against the requirements of the existing equipment.
• HACR rated: A documented rating for applications where HACR suitability is required.
