Why Choose the ABB XT2H 160 MA 160 Im=960–2240 3P Circuit Breaker?
The ABB XT2H 160 MA 160 Im=960–2240 3P, order code 1SDA076535R1, is a compact and high-performance moulded case circuit breaker (MCCB) designed for short-circuit protection in low-voltage electrical systems. As part of the ABB SACE Tmax XT series, it combines the XT2 frame with an MA magnetic release and H short-circuit performance level for demanding industrial and power-distribution applications.
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 magnetic short-circuit protection without thermal overload protection, making this configuration particularly suitable for applications where overload protection is provided separately, including coordinated motor circuits.
The XT2H 160 is supplied in a three-pole fixed configuration with front terminals. It has a rated operational voltage of up to 690 V AC and provides a rated ultimate short-circuit breaking capacity of 70 kA at 415 V AC, supporting reliable installation in switchboards, motor-control equipment and industrial distribution assemblies.

Reliable Magnetic Protection for Industrial Circuits
Magnetic-release circuit breakers such as the ABB XT2H MA are designed to respond rapidly to short-circuit currents. The adjustable instantaneous setting allows the magnetic protection threshold to be coordinated with the electrical characteristics of the protected circuit while separate equipment can provide overload protection where required.
The XT2H platform combines compact dimensions with high short-circuit performance for demanding low-voltage systems. With its 160 A rating, 960–2240 A magnetic adjustment range and 70 kA breaking capacity at 415 V AC, this configuration is well suited to industrial switchboards, motor circuits and electrical distribution assemblies requiring high-performance short-circuit protection.
Typical Applications
- Industrial motor circuits with separate overload protection.
- Motor control centres and machinery panels.
- Industrial low-voltage switchboards.
- Three-phase electrical distribution systems.
- OEM machinery and automation equipment.
- Circuits requiring adjustable instantaneous short-circuit protection.
