Square D KAL36250WB circuit breaker is a purpose-built protection device designed for demanding 3‑phase, 600V electrical systems. With a 250A rating and a 3‑pole configuration, this unit delivers reliable, clear disconnection to help keep industrial power distribution safe and downtime minimal. Engineered for maintenance, retrofit, and replacement scenarios, it’s the precise choice when exact specs matter and compatibility is non-negotiable.

Key specifications

• Amperage: 250A
• Poles: 3‑Pole
• Voltage: 600V
• Part number: KAL36250WB
• Compatibility note: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.

Why this part matters

In systems where three‑phase protection is essential, using the exact Square D KAL36250WB ensures proper mounting, electrical interface, and panel compatibility. This isn’t a generic replacement—it’s the specific reference your panel catalog expects, reducing the risk of incompatibility during routine service or an expansion project. By aligning the amperage, pole count, and voltage with your existing distribution, you maintain consistent protection and system behavior without surprises.

Ideal use cases

• Keep a ready replacement on hand for fast swap‑out in 3‑phase, 600V circuits.
• Retrofit: Refresh aging protection in a panel or distribution board that requires a 250A, 3‑pole unit.
• Replacement: Replaces a failed or tripped breaker in industrial or commercial facilities with 600V three‑phase services.

Who it's for

• Facilities with Square D panels or systems that specify the KAL36250WB reference.
• Electrical contractors performing panel refurbishments or upgrades on 600V distribution networks.
• Maintenance teams that prioritize precise part compatibility to minimize downtime and installation guesswork.

Practical tips for buyers

• Always verify panel catalog numbers and bus configuration to ensure the KAL36250WB matches your equipment.
• Confirm that 600V is appropriate for your distribution network before installation.
• Keep a spare KAL36250WB on hand for rapid replacement during scheduled maintenance or unplanned outages.
• Adhere to standard electrical safety practices during handling, installation, and testing of circuit protection devices.
