Why Choose the ABB XT2L 160 MA 80 Im=480-1120 3P F F Circuit Breaker?
The ABB 1SDA067788R1 is a high-performance moulded-case circuit breaker (MCCB) designed for short-circuit protection in low-voltage electrical systems. Part of the ABB SACE Tmax XT series, this XT2L model combines an 80 A rated current with an adjustable MA magnetic release for dependable protection in applications where overload protection is provided separately.
The breaker uses an MA magnetic-only trip unit with an adjustable instantaneous short-circuit setting of 480–1120 A, equivalent to approximately 6–14 times the rated current. This makes the device particularly suitable for motor circuits and other applications where a separate overload relay is used alongside the circuit breaker.
The XT2L 160 is supplied in a fixed three-pole configuration with front terminals. Its L short-circuit performance level provides a rated ultimate breaking capacity of 120 kA at 415 V AC, combining high fault-clearing capability with the compact dimensions and installation flexibility of the Tmax XT platform.
Key Advantages
- 80 A rated current for industrial and motor-protection applications.
- 480–1120 A adjustable instantaneous magnetic release for short-circuit protection.
- Wide 6–14 × In magnetic adjustment range supports coordination with motor starting currents.
- High 120 kA ultimate breaking capacity at 415 V AC.
- Three-pole fixed configuration suited to three-phase electrical systems.
- Front terminal connections simplify installation in switchboards and control panels.

Magnetic Short-Circuit Protection for Motor Circuits
An MA release provides magnetic short-circuit protection without a thermal overload function. This arrangement is particularly useful in motor circuits, where overload protection can be handled by a dedicated overload relay or motor-protection device while the circuit breaker provides rapid interruption of high short-circuit currents.
The adjustable 480–1120 A instantaneous setting allows the magnetic threshold to be coordinated with the characteristics of the protected circuit and motor starting current. Combined with the XT2L breaking performance, this provides a compact solution for short-circuit protection in demanding three-phase installations.
Typical Applications
- Three-phase motor circuits with separate overload protection.
- Industrial motor control centres and control panels.
- Machinery and automation systems.
- Industrial low-voltage switchboards.
- Short-circuit protection for feeders and equipment circuits.
- OEM electrical equipment and panel building.

Frequently Asked Questions
What is the ABB 1SDA067788R1 used for?
The ABB 1SDA067788R1 is an 80 A moulded-case circuit breaker with an adjustable magnetic release designed primarily to provide instantaneous short-circuit protection in low-voltage circuits, including motor applications using separate overload protection.
What is the magnetic trip range of the ABB XT2L 160 MA 80?
The MA magnetic release can be adjusted from 480–1120 A, corresponding to approximately 6–14 times the 80 A rated current.
Does the ABB 1SDA067788R1 provide thermal overload protection?
No. The MA release provides magnetic short-circuit protection rather than thermal overload protection. Where overload protection is required, it should be provided by an appropriate separate protection device for the application.
How many poles does the ABB 1SDA067788R1 have?
The ABB 1SDA067788R1 is a three-pole circuit breaker supplied in a fixed configuration with front terminal connections.
What is the breaking capacity of the ABB 1SDA067788R1?
The XT2L version has a rated ultimate short-circuit breaking capacity of 120 kA at 415 V AC, providing high fault-interruption capability for demanding low-voltage installations.
