1SDA100316R1 ABB Ekip Dip LSIG In=160A XT4 4p

Why Choose the ABB Ekip Dip LSIG In=160A XT4 4p 1SDA100316R1?

The ABB 1SDA100316R1 is an Ekip Dip LSIG electronic trip unit designed for compatible four-pole ABB SACE Tmax XT4 moulded case circuit breakers. Rated at 160 A, it provides configurable electronic protection for low-voltage AC electrical distribution systems where comprehensive overload, short-circuit and ground-fault protection is required.

Its LSIG protection functions combine long-time protection against sustained overloads, short-time protection for coordinated short-circuit response, instantaneous protection for severe short circuits and ground-fault protection for earth-fault conditions. This combination makes the trip unit particularly suitable for demanding distribution applications where selective and comprehensive circuit protection is important.

The 1SDA100316R1 is specifically configured for the ABB Tmax XT4 four-pole platform. It is supplied as a separate solid-state electronic release rather than a complete moulded case circuit breaker, allowing it to be combined with a compatible XT4 breaking part selected according to the required breaking capacity and installation configuration.

Key Advantages

• ABB Ekip Dip electronic protection for compatible Tmax XT4 moulded case circuit breakers.
• 160 A rated current for substantial low-voltage distribution loads.

Advanced LSIG Protection for Electrical Distribution

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

Because the 1SDA100316R1 is supplied as a separate electronic release, it can be combined with a compatible four-pole XT4 breaking part to create the required circuit-breaker assembly. This modular ABB Tmax XT architecture allows the 160 A LSIG protection unit and the required short-circuit breaking performance to be selected according to the characteristics of the electrical installation.

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 circuits requiring coordinated overload, short-circuit and ground-fault protection.
• ABB Tmax XT4 circuit-breaker assemblies requiring a 160 A LSIG electronic trip unit.
