Product Detailed Description

The Allen-Bradley 104-D210ED24 is a Bulletin 104-D series IEC reversing contactor designed for robust motor control and protection in industrial applications. It is part of the 100/104-D family, which covers power ratings from 50…500 kW @ 400V AC. This model features a 3-pole configuration with 3 main power poles, enabling the reversal of 3-phase motor rotation by interchanging two line conductors. It incorporates an electronic DC coil (ED) with a 24V DC rating (ED24), providing low-power operation and an integrated PLC interface for seamless integration with automation systems. The contactor is factory-assembled with a mechanical interlock to prevent simultaneous forward and reverse operation, ensuring safety. Auxiliary contacts are included (typically 1 N.O. + 1 N.C. standard, with options for expansion), and it supports AC-3 (motor starting/stopping) and AC-4 (plugging/inching) utilization categories. This contactor is environmentally friendly, compact, and compatible with Bulletin 193 electronic overload relays for complete motor starter assemblies.

Product Parameters

The following table summarizes key technical parameters for the 104-D210ED24 (based on 60°C ambient, 50 Hz operation; derating applies at higher temperatures):

Product Advantages

• Energy Efficiency: Electronic coil design offers low pick-up and hold-in power consumption, reducing operational costs and heat generation compared to traditional AC coils.
• Wide Voltage Tolerance: Operates across a broad range (0.85…1.1 x Us pick-up; 0.3…0.6 x Us drop-out), minimizing inventory needs for different coil voltages.
• Compact and Flexible: Space-saving dimensions allow easy integration into panel-mounted starter assemblies; common accessories across the 100-D family simplify design and maintenance.
• Enhanced Control Integration: Built-in PLC interface (EI) enables direct connection to automation systems like Allen-Bradley PLCs, improving system responsiveness and diagnostics.
• High Reliability and Longevity: 10 million mechanical operations and 1 million electrical cycles ensure minimal downtime; mechanically linked auxiliaries prevent unintended operations.
• Environmentally Friendly: RoHS-compliant materials and design support sustainable industrial practices without compromising performance.
• Safety Features: Mechanical interlock in reversing configuration prevents simultaneous energization, reducing risk of motor damage or hazards.

Precautions and Notes

• Installation Precautions: Mount on a vertical plane with finger- and back-of-hand-proof terminals; ensure maximum altitude of 2000 m. Use specified lugs or terminal kits for wiring to avoid loose connections or overheating.
• Coil Operation Notes: For the ED24 electronic coil, size the power supply to handle peak loads (<1 ms during energizing). Do not exceed 30.2V DC to prevent coil damage. Integrated suppressor modules protect against voltage spikes, but external varistors are recommended for harsh environments.
• Auxiliary Contact Compatibility: Auxiliaries are electronically compatible for low-power circuits (e.g., AC-12: 250V 0.1A; DC-13: 3…125V 1…100 mA); use for signaling only, not power switching.
• Derating and Environmental Warnings: Reduce current by 15% above 60°C; avoid dusty, corrosive, or high-vibration areas without enclosures. Not suitable for safety-critical circuits—use Bulletin 100S-D series for positively guided contacts.
• Short-Circuit Protection: Always pair with Type 2 coordination fuses (e.g., 400A gG @ 400V) to prevent contact welding; verify with IEC 60947-4-1 guidelines.
• Maintenance Notes: Periodically inspect for wear; do not disassemble. If using conventional DC coils (not applicable here), interconnect pickup winding with N.C. late-break auxiliary. Consult Rockwell Automation for custom configurations or special voltages.
• General Warning: Disconnect power before servicing; improper handling may void warranty and pose shock/fire risks.

Product Applications

The 104-D210ED24 is ideal for heavy-duty motor control in industrial environments requiring directional reversal, such as:

• Manufacturing and Automation: Reversing 3-phase motors in conveyor systems, assembly lines, and material handling equipment (AC-3/AC-4 categories).
• Elevators and Cranes: Plugging and inching operations for precise load positioning.
• Pumps and Fans: Capacitor switching (AC-6b) or transformer starting (AC-6a) in HVAC and water treatment systems.
• Compressors and Appliances: Hermetically sealed cooling systems (AC-8a/b) or low-inductive loads in commercial refrigeration.
• DC Motor Control: Shunt/series-wound motors or resistance furnaces (DC-3/DC-5).
• Wye-Delta Starters: High-inertia loads in mining, oil & gas, or wastewater processing. It integrates well with Allen-Bradley PLCs, HMIs, and overload relays for full motor protection in factories, warehouses, and processing plants handling up to 200 HP loads.
