Why Choose the ABB 1SDA128250R1 Closed Trip Unit Cover?
The ABB 1SDA128250R1 is a dedicated closed trip unit cover designed for compatible ABB SACE Emax 3 low-voltage power circuit breakers. Part of the ABB Emax 3 safety and protection accessory range, it provides a purpose-designed protective cover for the electronic trip unit area of compatible breakers.
This accessory is intended to protect the trip unit interface and its controls as part of an Emax 3 circuit-breaker installation. The closed-cover design provides a physical barrier over the trip unit area, helping prevent unintended direct access while maintaining a neat and integrated breaker assembly.
ABB specifies order code 1SDA128250R1 for Emax 3 frame sizes from E2.3 through E6.3. Its dedicated construction and direct compatibility make it a suitable choice for new switchgear assemblies, circuit-breaker configuration and replacement of the corresponding trip unit cover.

Dedicated Protection for Emax 3 Trip Units
The electronic trip unit is a central part of an ABB SACE Emax 3 circuit breaker, providing the interface for protection and operating functions. A dedicated cover helps physically protect this area and restrict casual or unintended access to its front controls.
Because the 1SDA128250R1 is designed specifically for the larger Emax 3 frame family, it integrates with compatible E2.3 through E6.3 breakers without requiring a generic enclosure solution. This makes it particularly useful in professionally assembled low-voltage switchboards where consistent component compatibility and protection are important.
