ABB EF96 Electronic Overload Relay for Motor Protection

ABB EF96 is an electronic overload relay used for protecting three-phase motors against overload and phase failure. It is commonly used in MCC panels, motor starters, pumps, compressors, conveyors and industrial machines where dependable motor protection is required.

The EF96 range covers motor currents from 20 A up to 100 A and is available in two main versions: EF96-56 and EF96-100. The motor current can be adjusted directly on the relay, while selectable trip classes allow the EF96 to be used for both normal and heavier motor starting conditions.

EF96 is self-powered from the motor circuit, so a separate auxiliary supply is not required for the overload protection function. Manual or automatic reset, TEST, STOP and trip indication are provided directly on the relay.
For an ABB EF96 electronic overload relay supplier in India, EF96-56 motor protection relay, EF96-100 overload relay or ABB electronic overload relay export requirement, buyers can share the motor current, contactor model and quantity for quotation.

ABB EF96 Models

ABB EF96-56

• ABB Order Code: 1SAX341001R1102

ABB EF96-56 vs EF96-100

The main difference between the two EF96 models is their current setting range.

EF96-56

• 20–56 A
• ABB code: 1SAX341001R1102

EF96-100

• 36–100 A
• ABB code: 1SAX341001R1101

There is an overlap between the two ranges. For motors operating within this overlap, the final relay selection should also consider the contactor and complete motor starter combination.

For replacement enquiries, buyers should specify the exact EF96-56 or EF96-100 model rather than asking only for ABB EF96.

ABB EF96 with AF Contactors

ABB EF96 relays are designed for use with ABB AF contactors in motor starter combinations.

Depending on the motor rating and starter design, EF96 relays are used with contactors such as AF80 and AF96, while other coordinated combinations are possible with suitable ABB components.

This type of arrangement is commonly used in:

• Direct-on-line motor starters
• MCC feeders
• Pump starters
• Compressor panels
• Conveyor motor starters
• Industrial machine panels

For new motor starter requirements, the motor full-load current and ABB contactor model should be provided together.

ABB EF96 Trip Class 10E, 20E & 30E

ABB EF96 provides selectable trip classes rather than being limited to one fixed overload characteristic.

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

Class 20E and 30E can be used where the motor has a longer acceleration period or a heavier starting load.

This gives panel builders and maintenance teams more flexibility when matching the overload relay to different motor applications.

Applications

ABB EF96 electronic overload relays are used in:

• MCC panels
• Motor starter panels
• Industrial pumps
• Pump control panels
• Compressors
• Conveyor systems
• Fans and blowers
• HVAC equipment
• Crushers and mills
• Material handling systems
• Packaging machinery
• Process plants
• Water and wastewater plants
• Machine tools
• Manufacturing equipment
• OEM machinery
• Factory automation
• Direct-on-line starters
• Star-delta starters
• Industrial motor control systems

ABB EF96 for Pumps, Compressors & Industrial Motors

EF96 is commonly used where medium-size industrial motors need adjustable electronic overload protection.

For example, it can be fitted in motor starters for pumps, compressors, conveyors and process machinery. If the motor remains overloaded for longer than the selected trip characteristic allows, the EF96 operates the control circuit and trips the motor contactor.

The phase failure function also helps protect the motor when one of the three supply phases is lost.

Choosing the Correct ABB EF96 Relay

For an ABB EF96 quotation, provide:

• Motor rated current
• EF96-56 or EF96-100, if already specified
• ABB order code
• ABB contactor model
• Required trip class, if specified
• Quantity
• Destination country

For a replacement requirement, a clear photograph of the existing EF96 relay and contactor can also help confirm the correct model.
