Why Choose the ABB Ekip Dip LIG In=40A XT4 3p 1SDA100303R1?
The ABB 1SDA100303R1 is an Ekip Dip LIG electronic trip unit designed for compatible three-pole ABB SACE Tmax XT4 moulded case circuit breakers. Rated at 40 A, it provides electronic protection for low-voltage AC power distribution systems where overload, instantaneous short-circuit and ground-fault protection are required.
Its LIG protection functions combine long-time protection against sustained overloads, instantaneous protection for severe short-circuit faults and ground-fault protection for earth-fault conditions. This makes the trip unit suitable for distribution circuits where dependable electronic protection and ground-fault detection are important.
The 1SDA100303R1 is specifically designed for the ABB Tmax XT4 three-pole platform. It is supplied as a separate solid-state release rather than a complete moulded case circuit breaker, allowing it to be combined with a compatible XT4 breaking part selected according to the installation's required short-circuit performance and mounting configuration.
Key Advantages
- ABB Ekip Dip electronic protection for compatible Tmax XT4 circuit breakers.
- 40 A rated current for lower-current XT4 distribution applications.
- LIG protection functions provide long-time, instantaneous and ground-fault protection.
- Electronic solid-state release provides dependable protection characteristics for AC power distribution.
- Designed specifically for three-pole ABB XT4 circuit-breaker configurations.
- Modular construction enables pairing with an appropriate XT4 breaking part for the required short-circuit performance.
Key Features
- ABB Ekip Dip LIG electronic trip unit.
- 40 A rated current (In).
- Designed for ABB SACE Tmax XT4.
- Three-pole compatibility.
- LIG protection: long-time, instantaneous and ground-fault functions.
- Solid-state electronic release.
- Designed for AC power distribution applications.
- Loose/configurable component for compatible XT4 circuit-breaker assemblies.
- Compatible with the modular ABB Tmax XT protection platform.
- Part of the ABB T-Max XT 250 Range.
Electronic LIG Protection for Power Distribution
The Ekip Dip LIG trip unit combines three complementary protection functions. Long-time protection responds to sustained overload conditions, instantaneous protection provides rapid response to severe short circuits, and ground-fault protection detects earth-fault conditions that could otherwise damage equipment or compromise the electrical installation.
Because the 1SDA100303R1 is supplied as a separate electronic release, it can be associated with a compatible three-pole XT4 breaking part to create a circuit-breaker configuration suited to the installation. This modular approach allows the breaking capacity and physical breaker configuration to be selected separately from the 40 A LIG protection release.
Typical Applications
- Industrial low-voltage switchboards.
- Main and sub-distribution panels.
- Three-phase AC electrical distribution systems.
- Commercial and infrastructure electrical installations.
- Manufacturing and process industry power systems.
- Feeder circuits requiring overload, short-circuit and ground-fault protection.
- ABB Tmax XT4 circuit-breaker assemblies requiring a 40 A LIG electronic release.
