Square D LHL36200 - 200 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Square D LHL36200 is a 200A, 600V, 3-pole molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Its compact form respects panel space while providing robust protection, making it a practical choice for modern electrical installations in residential, commercial, and light industrial settings.

Key Features

• Compact molded-case design maximizes available space inside panels, helping you fit more protection without expanding cabinet depth.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining thermal and magnetic sensing for both gradual overloads and instantaneous short circuits.
• OEM-compatible designed to pair with matching Square D loadcenters and panelboards for seamless installation and optimal performance.
• Versatile application suitable for residential, commercial, and light industrial circuits that require reliable branch-circuit protection.

Why it matters

In busy electrical spaces, panel real estate and dependable fault protection are critical. The LHL36200’s three-pole configuration provides balanced protection across phases, reducing the risk of unequal loading and nuisance trips. The thermal-magnetic trip mechanism responds quickly to faults while avoiding unnecessary trips during normal operation, helping keep systems running smoothly and safely.
