Why Choose the ABB XT5N 400 Ekip Dip LSIG In=250A 3p F F 1SDA100360R1?
The ABB 1SDA100360R1 is a complete SACE Tmax XT5N 400 moulded case circuit breaker (MCCB) designed for protection of demanding low-voltage AC electrical distribution systems. It combines a 400 A frame with a 250 A Ekip Dip LSIG electronic trip unit, three-pole construction, fixed mounting and front terminals.
Its Ekip Dip LSIG release provides long-time, short-time, instantaneous and ground-fault protection. These functions provide comprehensive electronic protection against sustained overloads, different levels of short-circuit fault and earth-fault conditions, making the breaker suitable for industrial distribution systems where protection coordination and ground-fault protection are required.
The XT5N performance level provides a short-circuit breaking capacity of 36 kA in the 380/415 V AC class. Combined with its 250 A trip-unit rating, fixed three-pole construction and front connections, the 1SDA100360R1 provides a robust solution for feeders, switchboards and power distribution installations.
Key Advantages
- Complete ABB SACE Tmax XT5N 400 MCCB with electronic protection.
- 250 A Ekip Dip LSIG trip unit installed within a 400 A XT5 frame.
- LSIG protection functions provide long-time, short-time, instantaneous and ground-fault protection.
- 36 kA short-circuit performance for the XT5N class at 380/415 V AC.
- Three-pole configuration for three-phase electrical distribution systems.
- Fixed mounting with front terminals for straightforward switchboard integration.

Advanced LSIG Protection for Electrical Distribution
The Ekip Dip LSIG electronic trip unit provides four complementary protection functions. Long-time protection responds to sustained overload conditions, short-time protection supports selective and coordinated response to short circuits, instantaneous protection provides rapid interruption during severe faults, and ground-fault protection responds to potentially damaging earth-fault currents.
The distinction between the breaker frame and trip-unit rating is important with this model. The XT5N 400 identifies the 400 A frame and N breaking-performance level, while the installed Ekip Dip LSIG release has a rated current of 250 A. The 1SDA100360R1 is supplied as a complete fixed three-pole MCCB with front terminals, rather than as a separate trip unit or breaking part.
Typical Applications
- Industrial low-voltage switchboards.
- Main and sub-distribution panels.
- Three-phase AC electrical distribution systems.
- Feeder and distribution circuit protection.
- Commercial and infrastructure power distribution.
- Manufacturing and process industry electrical systems.
- Installations requiring electronic ground-fault protection and short-circuit coordination.

Frequently Asked Questions
What is the ABB 1SDA100360R1?
The ABB 1SDA100360R1 is a complete Tmax XT5N 400 three-pole moulded case circuit breaker with a 250 A Ekip Dip LSIG electronic trip unit, fixed mounting and front terminals.
What protection functions does the Ekip Dip LSIG provide?
The Ekip Dip LSIG provides long-time, short-time, instantaneous and ground-fault protection, helping protect electrical distribution circuits against overloads, different levels of short-circuit fault and earth faults.
Is the ABB 1SDA100360R1 rated at 250 A or 400 A?
The breaker uses an XT5 400 A frame, while the installed Ekip Dip LSIG electronic trip unit has a rated current of 250 A. The 250 A figure therefore identifies the trip-unit current rating, while 400 A identifies the frame rating.
What is the breaking capacity of the ABB XT5N 400 1SDA100360R1?
The XT5N version belongs to ABB's 36 kA breaking-capacity class at 380/415 V AC, providing substantial short-circuit interruption capability for industrial and commercial low-voltage distribution systems.
How is the ABB 1SDA100360R1 configured for installation?
The 1SDA100360R1 is supplied as a fixed three-pole circuit breaker with front terminals, making it suitable for integration into compatible low-voltage switchboards and distribution panels.
