1SDA100195R1 ABB XT4N 250 Ekip Dip LSIG In=250A 4p F F MCCB

Why Choose the ABB XT4N 250 Ekip Dip LSIG In=250A 4p F F 1SDA100195R1?

The ABB 1SDA100195R1 is a high-performance Tmax XT4N moulded case circuit breaker (MCCB) designed for reliable protection of low-voltage electrical distribution systems. Supplied as a four-pole circuit breaker with an Ekip Dip LSIG electronic trip unit, it combines a 250 A rated current with configurable electronic protection for industrial, commercial and infrastructure applications.

Part of the advanced ABB SACE Tmax XT series, the XT4N 250 provides long-time, short-time, instantaneous and ground-fault protection through its Ekip Dip LSIG release. These LSIG functions provide comprehensive protection against overloads, short circuits and earth faults, while the electronic trip technology supports effective selectivity and protection coordination within modern electrical distribution systems.

The 1SDA100195R1 is configured as a fixed four-pole breaker with front terminals and a rated current of 250 A. It has a rated operational voltage of 690 V AC, a rated insulation voltage of 1000 V AC and a rated impulse withstand voltage of 8 kV, making it a robust solution for demanding low-voltage switchboards and power distribution installations.

Advanced LSIG Protection for Electrical Distribution

Moulded case circuit breakers protect electrical installations by automatically interrupting current when overloads or electrical faults occur. The ABB Ekip Dip electronic release provides adjustable protection characteristics, allowing the circuit breaker to be coordinated with the requirements of the installation and other protective devices throughout the distribution system.

With LSIG functionality, the 1SDA100195R1 provides long-time protection against sustained overloads, short-time protection for coordinated short-circuit response, instantaneous protection against severe short circuits and ground-fault protection for earth-fault conditions. The Ekip Dip platform also provides fault indication and thermal memory functionality, supporting effective protection and fault management in demanding electrical installations.

Typical Applications

• Industrial low-voltage switchboards.
• Main and sub-distribution panels.
• Three-phase and neutral electrical distribution systems.
• Commercial and infrastructure electrical installations.
• Manufacturing and process industry power systems.
• Feeder and distribution circuit protection.
