1SDA100340R1 ABB Ekip Dip LIG 63 A XT4 4-Pole Trip Unit

Why Choose the ABB 1SDA100340R1 Ekip Dip LIG 63 A XT4 4-Pole Trip Unit?

The ABB 1SDA100340R1 is an Ekip Dip LIG electronic trip unit designed for compatible SACE Tmax XT4 moulded-case circuit breakers. Rated at 63 A and configured for 4-pole applications, it provides configurable electronic protection for low-voltage power distribution systems.

As part of the ABB SACE Tmax XT protection platform, the Ekip Dip LIG release provides LIG protection, comprising long-time overload, instantaneous short-circuit and earth-fault functions. The electronic release enables the overload threshold to be adjusted over the 0.4–1 × In range, providing flexibility when coordinating protection with cables and connected distribution equipment.

The 1SDA100340R1 is specifically designed for XT4 4-pole circuit-breaker configurations and has a nominal current of 63 A. It is a separate electronic protection release rather than a complete moulded-case circuit breaker and must be combined with a compatible four-pole XT4 breaking part selected according to the required short-circuit performance and installation requirements.

Configurable LIG Protection for SACE Tmax XT4

The ABB Ekip Dip LIG platform combines three important electronic protection functions within a compact release. Long-time protection responds to sustained overload conditions, instantaneous protection provides rapid interruption during severe short circuits, and the earth-fault function adds dedicated protection against ground-fault currents within the electrical distribution system.

For the 63 A 1SDA100340R1, the long-time overload setting is adjustable from 0.4–1 × In, corresponding to approximately 25.2–63 A. As a separate four-pole electronic release, it can be paired with an appropriate SACE Tmax XT4 four-pole breaking part, allowing the short-circuit interruption performance and electronic protection characteristics of the complete circuit breaker to be selected for the application.

Typical Applications

• ABB SACE Tmax XT4 circuit-breaker assemblies.
• Industrial low-voltage power distribution.
• Commercial building electrical distribution.
• Main and sub-distribution switchboards.
• Manufacturing and process facilities.
• Four-pole feeder and cable protection.
• Generator and electrical installation protection.
• Applications requiring electronic earth-fault protection.
