ABB EF205-210 Electronic Overload Relay for Motor Protection

ABB EF205 is an electronic overload relay used for protecting larger three-phase motors against overload and phase failure. It is commonly used in MCC panels, motor starters, pumps, compressors, conveyors and heavy industrial machinery.

The EF205 range is built around the EF205-210, which covers an adjustable motor current range of 63 to 210 A. It is designed for direct mounting with ABB AF190 and AF205 contactors, making it suitable for compact high-current motor starter assemblies.

The relay is self-powered from the motor circuit, so no separate auxiliary supply is required for overload protection. It also provides selectable 10E, 20E and 30E trip classes, allowing the same relay to be used for motors with different starting characteristics.

For an ABB EF205 electronic overload relay supplier in India, EF205-210 motor protection relay, 1SAX531001R1101 requirement, or ABB overload relay export enquiry, buyers can share the motor current, contactor model and quantity for quotation.

ABB EF205 with AF190 & AF205 Contactors

ABB EF205-210 is designed for direct mounting with:

• ABB AF190
• ABB AF205

This combination is commonly used for higher-current motor starters in MCC panels and industrial control systems.

Typical requirements include:

• Large pump motors
• Compressors
• Conveyors
• Crushers
• Fans and blowers
• Process machinery
• Material handling systems

When selecting a new motor starter combination, the motor full-load current and contactor rating should be checked together.

ABB EF205 Trip Class 10E, 20E & 30E

EF205-210 provides three selectable overload trip classes.

Class 10E is generally used for motors with normal starting times.

Class 20E and 30E provide longer starting times before overload tripping and are useful for motors with heavier starting loads or longer acceleration periods.

This gives panel builders and maintenance teams more flexibility without needing different overload relay models for each starting condition.

Applications

ABB EF205 electronic overload relays are used in:

• MCC panels
• Large motor starter panels
• Industrial pumps
• Pumping stations
• Compressors
• Conveyor systems
• Crushers and mills
• Fans and blowers
• HVAC systems
• Material handling equipment
• Process plants
• Water and wastewater plants
• Steel plants
• Cement plants
• Mining equipment
• Manufacturing machinery
• OEM equipment
• Direct-on-line starters
• Star-delta starters
• Industrial motor control systems

ABB EF205 for High-Current Motor Protection

EF205 is particularly suited to motor applications above the current ranges handled by smaller ABB EF relays such as EF96 and EF146.

With an adjustable range of 63–210 A, the EF205-210 can cover several motor ratings with a single relay model.

This makes it useful for panel builders, industrial maintenance teams and OEMs dealing with larger motor starters.

Choosing the Correct ABB EF205 Relay

For an ABB EF205 quotation, provide:

• Motor rated current
• ABB contactor model
• Required trip class, if specified
• Existing ABB order code
• Quantity
• Destination country

For replacement requirements, a clear photograph of the existing overload relay and contactor can also help confirm the correct product.
