1CU5R | Circuit Breaker | 50A | 2-Pole | 240V

Engineered for reliability in demanding electrical environments, the 1CU5R circuit breaker is a 50A, 2-pole unit designed for 240V circuits. Ideal for maintenance, retrofit, and replacement tasks where precise specifications matter, this breaker protects your equipment and minimizes downtime.

Why this matters: A correctly rated 2-pole breaker on a 240V circuit ensures clean, predictable tripping behavior to safeguard wiring, motors, and control circuitry. The 1CU5R is the best-reference part number for compatibility when matching your panel or feeder configuration.

Key specifications:

• Amperage: 50A
• Poles: 2-Pole
• Voltage: 240V
• Reference/Part number: 1CU5R

Practical use cases:

• Maintenance and servicing of industrial panels that run on 240V two-pole circuits
• Retrofits to upgrade or standardize protection across a fleet of equipment
• Replacement for worn or failed breakers in compatible installations

How to confirm compatibility and avoid mismatches:

• Always refer to the part number 1CU5R as the primary compatibility reference.
• Verify your panel’s rating and the overcurrent protection requirement matches 50A / 2-pole / 240V.

Efficiency in the field? Absolutely. Adopting the 1CU5R as your standard for 50A, 240V, two-pole protection simplifies parts inventory, streamlines maintenance workflows, and reduces the risk of mismatched replacements—keeping critical systems online when it matters most.
