Eaton FDB2025

The Eaton FDB2025 is a 2-pole, 25A secondary circuit breaker rated for 480/600V AC, specifically engineered for low-voltage power distribution protection in distribution boxes, control panels, and industrial cabinets. Its compact dimensions (34 in height × 21 in width × 43 in length) enable seamless installation in space-constrained environments, while delivering reliable overload and short-circuit protection for critical electrical systems.

Key Technical Specifications

• Rated Current: 25 A
• Rated Voltage: 480 V / 600 V AC
• Pole Configuration: 2-pole (Single-phase)
• Short-Circuit Breaking Capacity: ≥ 10 kA
• Mechanical Dimensions: H 34 in (864 mm) × W 21 in (533 mm) × L 43 in (1092 mm)
• Weight: Approx. 225 lb (102 kg)

Product Features

• Compact Design: Space-saving and lightweight construction optimized for high-density mounting in panels and distribution boxes.
• Easy Maintenance: Open-structured design allows quick removal and inspection of internal components, minimizing maintenance downtime.
• High Reliability: Equipped with Eaton‘s standard thermal-magnetic trip unit, providing fast and precise overload and short-circuit protection.
• Strong Compatibility: Seamlessly integrates with Eaton’s other power distribution product lines (e.g., PVM, PVL series) for unified system management.

Construction & Components

• Enclosure: Die-cast metal housing offering robust mechanical strength and reliable protection rating.
• Trip Unit: Thermal-magnetic dual trip mechanism – thermal trip for long-term overload protection and magnetic trip for instantaneous short-circuit response.
• Contact Assembly: High-conductivity copper contacts ensuring low-impedance current flow and reduced heat generation.
• Terminal Blocks: Bolt-type terminal blocks facilitating on-site wiring and future replacement.
• Auxiliary Accessories: Optional handles, indicator lights, and locking devices to meet diverse on-site requirements.

Typical Applications

• Industrial Automation: Protects critical loads such as motors, pumps, and conveyor systems.
• Commercial Buildings: Branch circuit protection for lighting and HVAC systems in distribution cabinets.
• Infrastructure: Power distribution protection for public facilities including transportation and water/wastewater treatment.
• Renewable Energy: Secondary protection for solar/wind inverters and energy storage systems.

Installation Guidelines

• Sizing & Matching: Select appropriate rated current and breaking capacity based on load current, short-circuit current, and system voltage.
• Wiring Inspection: Ensure terminal blocks are securely fastened and conductor cross-sections comply with IEC/UL standards.
• Placement & Layout: Maintain sufficient heat dissipation space around the breaker and avoid direct proximity to high-temperature components.
• Labeling & Documentation: Clearly mark breaker numbers and functions in the distribution box, and document installation locations and parameters for future maintenance.

Maintenance Recommendations

• Regular Inspection: Conduct visual checks on the trip unit’s mechanical operation and terminal tightness every 6 months.
• Functional Testing: Use specialized test equipment to calibrate thermal and magnetic trip functions, ensuring compliance with specified operating times.
• Cleaning & Maintenance: Keep the enclosure surface free of dust and corrosive substances; wipe with a dry cloth when necessary.
• Replacement Strategy: Promptly replace the breaker in case of frequent tripping, contact ablation, or mechanical jamming to prevent system failure.

SEO Optimization Notes:

1. Keyword Integration: Strategically incorporates high-traffic terms (e.g., “Eaton FDB2025 secondary circuit breaker,” “low-voltage power distribution protection,” “industrial automation circuit breaker”) in title, headings, and body for Google search visibility.
2. Technical Accuracy: Maintains industry-standard terminology (e.g., “thermal-magnetic trip unit,” “short-circuit breaking capacity”) to align with target audience (engineers, procurement managers, facility operators).
3. Readability: Uses concise paragraphs, bullet points, and hierarchical headings (H1-H2) to enhance user experience and search engine crawlability.
4. Global Compliance: References international standards (IEC/UL) to appeal to global markets, supporting international marketing initiatives.
