JB21250SMW | Circuit Breaker | 250A | 3-Pole | 480V

Designed for demanding industrial electrical systems, the JB21250SMW circuit breaker delivers dependable overcurrent protection for 480-volt networks. This 3-pole unit is rated at 250A, providing robust interruption capability for motor loads, feeders, and control circuits in rugged environments.

As a precise, spec-matching device, the JB21250SMW is intended for maintenance, retrofit, and replacement projects where exact amperage, pole configuration, and voltage are required.

• Amperage: 250A
• Poles: 3-Pole
• Voltage: 480V
• Part number reference: JB21250SMW (best reference for compatibility)

Why this matters

• Exact-spec compatibility minimizes the risk of misfit parts and reduces downtime during replacements or upgrades.
• Using the correct 3-pole, 480V breaker helps protect critical loads, from motors to feeders, ensuring smoother operation and reliable interrupt protection.
• The JB21250SMW part number serves as the most reliable anchor for sourcing and cross-checks, simplifying procurement in busy maintenance environments.

Ideal use cases

• Maintenance and service of existing 480V distribution panels that require 250A, 3-pole protection.
• Retrofit projects updating legacy systems to current protection specs without changing panel hardware.
• Replacement for failed breakers in industrial plants where precise spec matching is essential for safe operation.

Important note: Confirm fit and ratings before ordering. Having the part number JB21250SMW handy helps ensure you’re pulling the exact unit needed, reducing mis-orders and speeding up your project timelines.
