Why Choose the ABB XT2L 160 MA 160 Im=960–2240 3P Circuit Breaker?
The ABB XT2L 160 MA 160 Im=960–2240 3P, order code 1SDA076536R1, is a high-performance moulded case circuit breaker (MCCB) designed for motor and short-circuit protection in demanding low-voltage electrical systems. As part of the ABB SACE Tmax XT series, it combines the compact XT2 frame with an MA magnetic release and the high-breaking-capacity XT2L execution.
This circuit breaker has a rated uninterrupted current of 160 A and an adjustable instantaneous magnetic release range of 960–2240 A. The MA release provides instantaneous short-circuit protection without thermal overload protection, making this configuration particularly suitable for motor circuits where overload protection is provided by a separate coordinated device.
The XT2L 160 is supplied in a three-pole fixed configuration with front terminals. The XT2L performance level provides a rated ultimate short-circuit breaking capacity of 120 kA at 415 V AC, making this compact circuit breaker suitable for installations where high prospective fault currents demand substantial interruption capability.

High-Performance Short-Circuit Protection for Motor Circuits
Magnetic-release circuit breakers such as the ABB XT2L MA are designed to react rapidly when short-circuit current exceeds the selected instantaneous threshold. The adjustable magnetic setting enables protection to be coordinated with motor starting currents and other circuit characteristics while a separate overload device provides the required thermal overload protection.
The XT2L combines compact Tmax XT construction with exceptionally high short-circuit interruption capability. Its 160 A rating, adjustable 960–2240 A magnetic release and 120 kA Icu at 415 V AC make this configuration particularly suitable for motor-control centres, industrial machinery and distribution systems with high prospective fault levels.
Typical Applications
- Industrial motor circuits with separate overload protection.
- Motor control centres and motor starter assemblies.
- Industrial machinery and production equipment.
- High-fault-level low-voltage switchboards.
- Three-phase power distribution systems.
- OEM automation and machine-building applications.

Frequently Asked Questions
What is the ABB 1SDA076536R1?
The ABB 1SDA076536R1 is an XT2L 160 three-pole fixed moulded case circuit breaker with front terminals and an MA magnetic release for short-circuit protection.
What is the rated current of the ABB XT2L 160 1SDA076536R1?
The circuit breaker has a rated uninterrupted current of 160 A.
What does Im=960–2240 mean on the ABB XT2L 160?
It identifies an adjustable instantaneous magnetic trip range from 960 to 2240 A, allowing the short-circuit protection threshold to be coordinated with the protected circuit.
What type of protection does the MA release provide?
The MA magnetic release provides instantaneous short-circuit protection and does not provide thermal overload protection, so suitable overload protection is normally coordinated separately where required.
What is the breaking capacity of the ABB XT2L 160?
The XT2L performance level provides a rated ultimate short-circuit breaking capacity of 120 kA at 415 V AC.
How many poles does the ABB 1SDA076536R1 have?
This circuit breaker has three poles and is designed for three-phase electrical applications.
How is the ABB XT2L 160 1SDA076536R1 installed?
This version is supplied in a fixed configuration with front terminals for integration into switchboards, motor-control centres and industrial electrical panels.
