Square D KAL3625029M - 250 A, 3-Pole Circuit Breaker | AmpState

When you need reliable protection for large electrical circuits, the Square D KAL3625029M stands out. This 250 A, 3-pole molded case circuit breaker from Square D is engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters, making it a trusted choice for residential, commercial, and light industrial applications.

Key features that matter in the field

• 250 A amperage rating provides robust protection for main or feeder circuits in demanding panels
• Three-pole design supports balanced three-phase distribution and proper phase coordination
• Compact molded case design maximizes panel space without sacrificing protection
• Thermal-magnetic trip unit delivers stable, repeatable protection across temperature variations and fault conditions
• Designed for seamless compatibility with matching OEM loadcenters and panelboards for straightforward installation
• Suitable for residential, commercial, and light industrial environments where reliable overcurrent protection is essential

Why this breaker stands out

The integrated thermal-magnetic trip technology combines the benefits of both thermal (overload) and magnetic (short-circuit) protection. This means more predictable performance with fewer nuisance trips during normal temperature shifts, and immediate interruption when a fault occurs. The 3-pole configuration ensures correct phase alignment in three-phase systems, reducing the risk of imbalanced loads in feeders and distribution panels.

Practical use cases

• Main service protection in larger residential and small commercial installations requiring a 3-pole, 250 A solution
• Feeder protection in panelboards serving lighting, outlets, and light machinery in commercial settings
• Upgrades or replacements in OEM panels where a compatible Square D unit is preferred for consistent performance
