Why Choose the ABB XT4X 160 MA 10 1SDA101956R1 Circuit Breaker?
The ABB 1SDA101956R1 is a SACE Tmax XT4X moulded case circuit breaker (MCCB) designed particularly for motor short-circuit protection in demanding low-voltage electrical systems. This three-pole fixed breaker uses ABB’s MA magnetic release, with a rated current of 10 A and an adjustable instantaneous magnetic trip setting of 50–100 A.
As part of the ABB SACE Tmax XT family, the XT4X combines the compact XT4 frame with exceptionally high short-circuit interruption performance. The X performance level provides an ultimate short-circuit breaking capacity of 200 kA at 415 V AC, making the 1SDA101956R1 suitable for motor circuits installed in systems with very high prospective fault currents.
The 1SDA101956R1 is supplied as a fixed three-pole circuit breaker with front terminals. Its MA release is dedicated primarily to instantaneous short-circuit protection rather than conventional thermal overload protection, making it particularly suitable for motor circuits where appropriately coordinated overload protection is provided separately.
Key Advantages

High-Performance Magnetic Protection for Motor Circuits
The MA magnetic release is designed to respond rapidly to high short-circuit currents while allowing the protection threshold to be coordinated with motor starting characteristics. On the 1SDA101956R1, the instantaneous magnetic threshold is adjustable between 50 A and 100 A, equivalent to 5–10 times the breaker’s 10 A rated current. This allows the breaker to tolerate appropriate motor starting currents while providing rapid interruption of severe short-circuit faults.
The XT4X performance level is particularly suited to installations with exceptionally high prospective fault currents, delivering 200 kA Icu and Ics at 415 V AC. Because the MA release is intended for magnetic short-circuit protection, suitable motor overload protection should be provided separately and coordinated with the breaker as part of the complete motor protection system.
Typical Applications
- Three-phase motor short-circuit protection.
- Motor control centres and motor starter assemblies.
- Industrial machinery and production equipment.
- Pumps, fans and compressor circuits.
- Conveyors and material-handling systems.
- Industrial switchboards with high prospective fault currents.
- Manufacturing and process-industry electrical systems.
- Motor circuits using separate coordinated overload protection.

Frequently Asked Questions
What is the ABB 1SDA101956R1 used for?
The ABB 1SDA101956R1 is a 10 A three-pole XT4X moulded case circuit breaker designed particularly for magnetic short-circuit protection of motors and compatible low-voltage circuits.
What type of trip unit is fitted to the ABB 1SDA101956R1?
The breaker uses an ABB MA magnetic release. It provides adjustable instantaneous magnetic short-circuit protection rather than conventional thermal overload protection.
What is the magnetic trip range of the ABB XT4X 1SDA101956R1?
The instantaneous magnetic trip setting is adjustable from 50 A to 100 A, corresponding to 5–10 times the breaker’s 10 A rated current.
What is the breaking capacity of the ABB XT4X 160?
The XT4X performance level provides an ultimate short-circuit breaking capacity of 200 kA at 415 V AC. For this configuration, ABB also specifies a service short-circuit breaking capacity of 200 kA at 415 V AC.
Does the ABB 1SDA101956R1 provide motor overload protection?
The MA release is designed primarily for magnetic short-circuit protection and does not provide conventional thermal overload protection. For motor applications, an appropriately selected and coordinated external overload protective device should therefore be used.
