Square D LHL36250 - 250 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Square D LHL36250 — a 250A, 600V, 3-pole molded case circuit breaker engineered to deliver dependable branch circuit overcurrent and short-circuit protection for panelboards and load centers. Built for demanding electrical environments, this breaker integrates advanced protection with space-efficient design to keep your systems safe and flowing smoothly.

Why this breaker stands out

• Compact molded case design maximizes panel space without compromising protection, helping you fit the protection you need in tighter installations or dense electrical rooms.
• Thermal-magnetic trip unit delivers stable, repeatable protection by addressing both overloads (thermal) and short circuits (magnetic) with precise trip curves. This means fewer nuisance trips and more predictable performance in real-world conditions.
• Three-pole construction is ideal for 3-phase systems common in commercial and light industrial applications, ensuring coordinated protection across all phases.
• OEM-compatible integration designed to drop into matching OEM load centers and panelboards, guaranteeing proper fit, bus compatibility, and straightforward installation.
• Versatile applications suited for residential, commercial, and light industrial environments that demand reliable branch-circuit protection and rapid fault interruption.

What problems does it solve?

The LHL36250 provides robust protection for critical circuits against overcurrent and short circuits, reducing the risk of wiring damage, equipment downtime, and fire hazards. Its thermal-magnetic trip ensures fast, predictable responses to faults while minimizing unnecessary interruptions in normal operation.

Ideal use scenarios

- Protect branch circuits feeding critical equipment in commercial spaces, such as offices, retail, and data centers.

- Safeguard residential subpanels and multi-wire branch circuits where space-saving protection is a priority.

- Serve light industrial panels where reliable 3-phase protection is essential and compatibility with OEM load centers is a must.
