ABB EF146-150 Electronic Overload Relay for Motor Protection

ABB EF146 is an electronic overload relay used for protecting three-phase motors against overload and phase failure. It is mainly used with larger ABB AF contactors in MCC panels, motor starters, pumps, compressors, conveyors and other industrial motor applications.

The EF146 range is built around the EF146-150, which covers an adjustable motor current range of 54 to 150 A. The relay is self-powered from the motor circuit, so no separate auxiliary supply is required for normal overload protection.

A useful feature of the EF146-150 is the selectable 10E, 20E and 30E trip class. This allows the relay to be used for motors with normal starting times as well as applications where the motor takes longer to accelerate.

For an ABB EF146 electronic overload relay supplier in India, EF146-150 motor protection relay, 1SAX351001R1101 supplier or ABB overload relay export requirement, buyers can share the motor current, contactor model and quantity for quotation.

ABB EF146 with AF Contactors

ABB EF146-150 is designed for use with larger ABB AF contactors, particularly:

• ABB AF116
• ABB AF140
• BB AF146

This combination is commonly used in motor starter and MCC applications where motor currents are above the ranges handled by EF65 and EF96 relays.

For a new motor starter requirement, the motor full-load current and contactor model should be checked together before selecting the overload relay.

ABB EF146 Trip Class 10E, 20E & 30E

EF146-150 provides selectable trip classes, giving more flexibility for different motor starting conditions.

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

Class 20E and 30E are suitable where the motor has a longer acceleration time or a heavier starting load.

This makes the EF146 useful for pumps, compressors, conveyors and other industrial equipment where starting conditions can vary considerably.

Applications

ABB EF146 electronic overload relays are used in:

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

Choosing the Correct ABB EF146 Relay

For an ABB EF146 quotation, buyers should provide:

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

For replacement requirements, share a clear photograph of the existing overload relay and contactor. This helps confirm that EF146-150 – 1SAX351001R1101 is the correct unit for the existing starter.
