1. Product Introduction

The ABB EHDB220-21-11 is part of ABB’s EHDB Drive Contactor series. The EHDB line of contactors is designed to be used in conjunction with solid-state DC adjustable-speed drive systems. In normal operation, these contactors are not required to switch the load frequently; their main role is to provide emergency or protection disconnection capability, and support dynamic braking circuits.library.e.abb.com

The “220” in the model suggests a current class around 220 A, and the suffix “-21-11” typically designates a certain control coil voltage (for example, 110V 50Hz in this variant) ABB Group+1

2. Typical Technical Specifications

Here are reference / typical specs (subject to confirmation by manufacturer datasheet):

• Type: EHDB Drive Contactor

• Current Class: ~ 220 A (EHDB220 series)

• Poles: 2 poles (2 N.O.) or optional 3 poles (2 N.O. + 1 N.C.)

• Interrupting / DC Break Capacity: capable of DC braking interruption up to 600 V DC (in suitable versions)

• Auxiliary Contacts: Standard 1 N.O. + 1 N.C., up to 8 total auxiliary contacts possible by expansion

• Coil Voltage: 110 V 50Hz (for -21-11 variant)

• Coil Tolerance: Operates properly in 85% to 110% of rated coil voltage

• Contact Design: Double-break contact arrangement with magnetic arc chambers for faster arc extinction

• Lifespan: High mechanical and electrical endurance (millions of operations)

• Coil Consumption / Holding Power: modest, in designed limits (tens of VA)

• Operating Temperature: industrial range (e.g. –40 °C to +55 °C)

• Standards / Certifications: IEC / EN 60947 series; available UL / CSA versions

3. Advantages & Features

• Designed specifically for drive systems, so it is optimized not for frequent switching of load, but safe disconnect and braking support.

• High current capacity and DC interruption ability make it suitable for demanding drive applications.

• Expandable auxiliary contacts allow flexible signal feedback and monitoring.

• Double-break contacts with magnetic arc extinguishing provide reliable arc suppression.

• Coil voltage tolerance (85%–110%) gives flexibility under fluctuating control voltages.

• Modular design allows replacement of coils, arc chutes, or contact assemblies, facilitating field maintenance.

4. Application Areas

• Integration with DC adjustable-speed drives for motor control

• Emergency shutdown / protection switch in motor circuits

• Dynamic braking systems (via N.C. auxiliary contact to braking resistor)

• Heavy industrial machinery drives (e.g. extruders, rolling mills)

• DC drive systems in power, mining, cement, and metallurgy industries

5. Precautions & Recommendations

1. Coil Voltage Accuracy: Ensure the control coil voltage matches the variant (e.g. 110V 50Hz) to assure correct operation.

2. Use as Emergency / Protection Device: EHDB contactors are not intended for frequent switching of main load in normal operation.

3. Ventilation & Heat: Install in locations with sufficient cooling; avoid direct exposure to heat sources.

4. Shielded Wiring: Use shielded and twisted-pair cables for coil and auxiliary lines to minimize electrical noise.

5. No Hot-Plugging: Avoid removing or replacing parts while powered, to prevent arcs or damage.

6. Regular Inspection: Check contact wear, coil heating, auxiliary contact functionality periodically.

7. Proper Grounding & Protection: Ensure correct grounding of frame, coil circuits, and auxiliary circuits to avoid fault propagation.
