Siemens | LMXD62A800L | Circuit Breaker | 800A | 3-Pole | 600V

Meet the Siemens LMXD62A800L, a high-current circuit breaker built for heavy-duty 3-phase systems. Rated at 800 A, with 3 poles and a 600 V maximum, it's designed for maintenance, retrofit, and replacement projects where exact specifications matter. Use the part number LMXD62A800L as your primary compatibility reference to ensure a seamless fit in compatible Siemens panels.

Key Specifications

• Amperage: 800 A
• Poles: 3-Pole
• Voltage: 600 V
• Part number: LMXD62A800L

Designed for Maintenance, Retrofit, and Replacement

The LMXD62A800L is intended for scenarios where you need to upgrade, replace, or retrofit a panel with a like-for-like current rating and form factor. This ensures minimal downtime and preserves the existing protection scheme while accommodating demanding loads.

Why This Siemens Breaker Stands Out

• Exact compatibility reference: The part number LMXD62A800L provides the most reliable cross-reference for fit in compatible Siemens panels.
• High-current capability: With an 800 A rating, it supports heavy-load facilities and large-distribution feeders typical in commercial and light-industrial settings.
• 3-pole configuration for 3-phase systems: Ideal for balanced or near-balanced three-phase power distribution, helping maintain stable protection across phases.
• Industry-standard 600 V rating: Suitable for common commercial and industrial power distribution voltages while maintaining robust protection margins.

Use Scenarios

Examples include upgrading large feeders in commercial buildings, retrofitting industrial equipment circuits, or replacing aging breakers in maintenance shutdowns. This unit is a like-for-like swap in compatible Siemens electrical infrastructure, helping you keep system protection consistent with existing design parameters.

Installation and Safety

Installation should follow all relevant electrical codes and be performed by qualified personnel. Before ordering, always confirm fit and ratings. The product notes emphasize that the part number is the best reference for compatibility, ensuring you select the correct 800 A, 3-pole, 600 V device for your panel.
