LM3700L | Circuit Breaker | 700A | 3-Pole | 600V

Meet the LM3700L, a purpose-built industrial circuit breaker designed to protect three-phase power systems with precision and reliability. With a 700A rating and a 3-pole configuration, this unit is tailored for heavy-load environments requiring robust protection at up to 600V.

Why choose LM3700L for your system

• Precise three-phase protection: The 3-pole design ensures synchronized isolation across all phases, reducing the risk of unbalanced faults and equipment damage.
• High-capacity current handling: The 700A rating supports large motors, presses, conveyors, and other demanding loads without nuisance trips from transient surges.
• 600V applicability: Engineered for standard industrial distribution networks, data centers, manufacturing lines, and infrastructure where 600V class equipment is used.
• Direct replacement compatibility: The LM3700L is identified by its part number as the best reference for matching fit, ratings, and mounting in your existing panel or switchgear.

Ideal use cases

• Maintenance and retrofit projects where you need a like-for-like replacement that preserves electrical characteristics and protection coordination.
• New installations where you require a dependable, high-current breaker in a 3-pole configuration for three-phase systems.
• Equipment refresh in industrial facilities, pump stations, processing lines, and large-motor drives.

How to ensure the right fit

Before ordering, verify the fit and ratings align with your equipment. Notes: Confirm fit and ratings before ordering. The LM3700L part number is the best reference for compatibility. While installing, confirm the enclosure rating and mounting interface match your panel's specifications.

Practical procurement tips

• Keep a procurement trail: record part numbers, amperage, voltage, and pole configuration for future replacements.
• Store spares in original packaging when available to protect terminals and contact surfaces from corrosion or damage.
• Coordinate replacements with maintenance schedules to minimize downtime during retrofits or upgrades.

Designed for reliability in industrial environments, the LM3700L 700A 3-Pole 600V circuit breaker makes maintenance, retrofit, and replacement straightforward—delivering consistent protection and peace of mind for critical power distributions.
