Eaton Cutler-Hammer UVH2RP21K 250A 24V Circuit Breaker, Undervoltage Release | AmpState

The Eaton Cutler-Hammer UVH2RP21K is a 250 A, 24 V circuit breaker equipped with an undervoltage release (UVR) designed for precise protection in panelboards, load centers, and electrical distribution systems. Built for professional installations, it’s the OEM-grade choice when a direct part-number match matters for maintenance, stocking, and reliability.

• Integrated undervoltage release (UVR): automatically trips if control power drops, safeguarding downstream equipment and preventing unsafe energization during power interruptions.
• High-current capability: 250 A rating makes it suitable for feeders and critical circuits in industrial and commercial settings.
• 24 V control voltage: aligns with standard control circuits used in motor starts, relays, and automation panels.
• Exact part-number fit for minimal downtime: ideal for panel builders and maintenance teams who require a precise Eaton UVH2RP21K replacement in existing assemblies.
• Reliable protection across distribution equipment: designed to work seamlessly in panelboards, load centers, and general electrical distribution networks, helping to reduce unexpected outages.

Who benefits most from the UVH2RP21K? electricians, panel builders, and maintenance crews responsible for critical infrastructure who need predictable performance, fast replacements, and a verified part-number match. It’s particularly valuable in facilities where control power loss could lead to unsafe conditions or equipment damage, and where spare inventory must align exactly with OEM specifications.

Practical use scenarios include replacement in existing Eaton systems, new installations within control-driven panels, and spare stock for service fleets that prioritize accurate part matching to minimize install time and avoid compatibility issues.
