Why Choose the ABB 1SDA067495R1 MA 125 Im=625...1250 XT4 3p Trip Unit?
The ABB 1SDA067495R1 is a three-pole MA magnetic trip unit designed for use with ABB SACE Tmax XT4 moulded-case circuit breakers in motor protection applications. With a rated current of 125 A and an adjustable instantaneous magnetic trip range of 625–1250 A, it provides rapid protection against high short-circuit currents.
As part of the ABB SACE Tmax XT circuit breaker system, the MA release is specifically designed for motor circuits where instantaneous magnetic protection is required and overload protection is provided separately. This arrangement allows effective coordination between the circuit breaker, motor overload protection and the electrical characteristics of the connected motor.
The 1SDA067495R1 is a three-pole AC/DC magnetic release with a rated current of 125 A. Its adjustable instantaneous protection setting of 625–1250 A allows the magnetic threshold to be coordinated with motor starting currents while maintaining rapid short-circuit fault protection.
Key Advantages
- Dedicated magnetic short-circuit protection for motor applications.

Reliable Magnetic Protection for Motor Circuits
Magnetic trip units provide rapid protection against high fault currents by operating when current exceeds the selected instantaneous threshold. In motor circuits, an adjustable magnetic setting allows the protection threshold to accommodate normal motor starting currents while still providing fast disconnection during severe short-circuit faults.
The ABB MA range is designed for motor protection applications where overload protection is handled separately. When the 1SDA067495R1 is combined with a compatible Tmax XT4 circuit breaker and correctly coordinated overload protection, it provides a robust solution for protecting industrial motors and associated circuits against short-circuit faults.
Typical Applications
- Industrial motor protection circuits.
- Motor control centres and MCC panels.
- Pumps, fans and compressor motor circuits.
- Conveyors and material handling equipment.
- Industrial machinery and production equipment.
- Motor circuits using separate overload protection.
- ABB Tmax XT4 moulded-case circuit breaker installations.

Frequently Asked Questions
What is the ABB 1SDA067495R1 used for?
The ABB 1SDA067495R1 is an MA magnetic trip unit designed for compatible ABB Tmax XT4 moulded-case circuit breakers, providing instantaneous short-circuit protection for motor protection applications.
What is the rated current of the ABB MA 125 XT4 3p?
The trip unit has a rated current of 125 A.
What is the magnetic trip range of the 1SDA067495R1?
The instantaneous magnetic trip setting is adjustable from 625–1250 A, allowing the short-circuit protection threshold to be coordinated with the motor circuit.
Does the ABB MA 125 provide overload protection?
The MA trip unit provides instantaneous magnetic short-circuit protection rather than thermal overload protection. Appropriate separate overload protection is therefore used where required by the motor protection system.
Which circuit breaker is the 1SDA067495R1 designed for?
The trip unit is designed for use with compatible ABB SACE Tmax XT4 moulded-case circuit breakers.
