MXL36800G - 800 Amp Circuit Breaker

MXL36800G - 800 Amp Circuit Breaker

Finding the right replacement breaker usually comes down to the details. The MXL36800G is a 3-pole, 800-amp Type MXL molded-case circuit breaker with a cable-in/cable-out configuration. Its interrupting ratings are 25 kA at 600 VAC, 65 kA at 480 VAC, and 65 kA at 240 VAC.

This breaker also offers adjustable protection settings, including long-time ampere rating and delay, short-time ampere rating and delay, instantaneous pickup, and ground-fault pickup and delay. It is a current-limiting, thermal-magnetic breaker with Micrologic functionality included in the supplied specifications.

For maintenance teams working with older electrical equipment, the important thing is getting a breaker that matches the existing application. If your equipment calls for an MXL36800G, matching the amperage, poles, voltage, interrupting capacity, connections, and protection functions can help avoid unnecessary changes to the existing setup. It's a straightforward replacement option for compatible MXL applications and built to last in its intended use.

Material Compliance and Certifications

• The available MXL36800G specifications did not include specific material compliance, listing, or certification information. If your installation requires a particular certification or listing, check the breaker nameplate and authoritative product documentation before installation.

Where It Works Best

• The MXL36800G is best suited for existing electrical equipment designed for a compatible Type MXL 800A, 3-pole breaker. It can be especially useful when you're maintaining a legacy system and want to preserve the original equipment configuration instead of making unnecessary changes.
  
• Before using it as a replacement, check the complete application—not just the amp rating. Confirm the part number, number of poles, voltage, A.I.C. rating, cable connections, physical fit, protection settings, and equipment compatibility.
