Why Choose the ABB XT4X 160 MA 32 Im=160...320 3P Circuit Breaker?
The ABB XT4X 160 MA 32 Im=160...320 3P is a compact and robust three-pole moulded case circuit breaker (MCCB) designed for protection and switching in low-voltage electrical systems. As part of the ABB SACE Tmax XT4 series, it combines a 160 A frame with a 32 A MA magnetic-only trip unit for applications where short-circuit protection is required without integral thermal overload protection.
The MA magnetic trip unit provides instantaneous short-circuit protection with an adjustable magnetic threshold of 160–320 A. This magnetic-only protection characteristic makes the breaker particularly suitable for motor circuits where overload protection is provided separately by a motor protection relay, thermal overload relay or other dedicated protective device.
With its three-pole configuration, fixed mounting and front-terminal arrangement, the 1SDA107708R1 is designed for straightforward integration into switchboards, motor control centres and industrial control panels. The XT4X platform combines ABB Tmax XT construction with application-focused magnetic protection for dependable three-phase circuit switching and short-circuit protection.

Magnetic Short-Circuit Protection for Motor Circuits
Magnetic-only moulded case circuit breakers are commonly used where rapid short-circuit protection is required while overload protection is handled by a separate protective device. The ABB MA trip unit responds to high fault currents without incorporating the thermal overload characteristic found in conventional thermomagnetic releases.
For the 1SDA107708R1, the instantaneous magnetic threshold can be adjusted from 160–320 A. This enables the breaker to be coordinated with compatible motor starting equipment and separate overload protection while providing short-circuit interruption through the ABB SACE Tmax XT4 platform.
Typical Applications
- Three-phase motor circuits with separate overload protection.
- Motor control centres and industrial control panels.
- Industrial machinery and automation systems.
- Pumps, fans and conveyor motor circuits.
- Manufacturing and process equipment.
- Low-voltage circuits requiring magnetic-only short-circuit protection.
