LDC3500 - 500 Amp Circuit Breaker

LDC3500 - 500 Amp Circuit Breaker

There's more to matching an LDC3500 than finding a 500A breaker with three poles. The trip setup matters. So do the terminals, interrupting ratings, and physical size. The LDC3500 is a Type LDC thermal-magnetic circuit breaker with an interchangeable trip unit, and this version comes with load terminals. Compare the complete configuration—not simply the LDC name or 500A rating—with the breaker being replaced. When properly matched, installed, and maintained within your stated ratings, the LDC3500 is built to last.

Key Features and Benefits

• 500A, three poles: The obvious place to begin when checking the LDC3500 against an existing breaker.
• Interchangeable trip unit: An important part of this breaker's configuration and something you'll want to match carefully.
• Type LDC: Helps narrow down compatibility when working with existing Type LDC equipment.
• Thermal-magnetic design: The specified protection configuration for the LDC3500.
• Load terminals are included: Useful to know up front when checking the required connection arrangement.
• 40°C rated: Another application detail to confirm against the equipment requirements.
• HACR rated: Identified as HACR-rated in the supplied product specifications.

Material Compliance and Certifications

The information supplied for the LDC3500 identifies it as HACR-rated. No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance information was provided for this exact part number, so don't assume those approvals.

Where It Works Best

The LDC3500 belongs in applications where existing or legacy equipment calls for the same 500A, three-pole Type LDC thermal-magnetic configuration with an interchangeable trip unit.
