1SDA100254R1 ABB XT4H 160 Ekip Dip LSIG In=160A 4p F F MCCB

Why Choose the ABB XT4H 160 Ekip Dip LSIG In=160A 4p F F 1SDA100254R1?

The ABB 1SDA100254R1 is a high-performance Tmax XT4H moulded case circuit breaker (MCCB) designed for dependable protection of low-voltage AC electrical distribution systems. Supplied as a four-pole circuit breaker with an Ekip Dip LSIG electronic trip unit, it combines a 160 A rated current with configurable electronic protection for demanding industrial, commercial and infrastructure applications.

Part of the ABB SACE Tmax XT series, the XT4H 160 provides long-time, short-time, instantaneous and ground-fault protection through its Ekip Dip LSIG release. These LSIG functions provide comprehensive protection against sustained overloads, short circuits and earth faults while supporting effective protection coordination throughout modern low-voltage distribution systems.

The 1SDA100254R1 is configured as a fixed four-pole breaker with front terminals. The XT4H designation identifies ABB's high short-circuit performance level, while the 160 A Ekip Dip LSIG release provides microprocessor-based electronic protection. Its four-pole construction makes it particularly suitable for three-phase distribution systems where switching and protection of the neutral conductor are required.

Key Advantages

• Complete ABB Tmax XT4H 160 moulded case circuit breaker for low-voltage power distribution.
• 160 A Ekip Dip electronic trip unit for configurable circuit protection.
• LSIG protection functions cover long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault conditions.
• XT4H high-breaking-capacity performance for demanding electrical distribution installations.
• Four-pole fixed configuration suitable for three-phase systems incorporating a neutral conductor.
• Front terminals support straightforward integration into switchboards and distribution panels.

Key Features

Advanced LSIG Electronic Protection

The Ekip Dip LSIG electronic trip unit provides four complementary protection functions. Long-time protection responds to sustained overload conditions, short-time protection supports coordinated response to short circuits, instantaneous protection provides rapid interruption during severe faults, and ground-fault protection detects potentially damaging earth-fault conditions.

Combining these protection functions with the XT4H high-performance frame gives the 1SDA100254R1 a versatile protection profile for demanding distribution systems. Its four-pole construction also allows the device to be applied where all three phases and the neutral conductor need to be incorporated into the circuit-breaker arrangement.

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.
