Why Choose the ABB T5N 400 Ekip E-LSIG 400 A 3P Fixed Circuit Breaker 1SDA081048R1?
The ABB 1SDA081048R1 is an ABB SACE Tmax T5N 400 moulded-case circuit breaker (MCCB) equipped with an Ekip E-LSIG electronic trip unit. Rated at 400 A, this three-pole breaker is designed for low-voltage power distribution applications requiring electronic protection and dependable circuit isolation.
Its Ekip E-LSIG trip unit provides a comprehensive combination of long-time, short-time, instantaneous and ground-fault protection. This makes the breaker suitable for protecting feeders and distribution circuits where coordinated electronic protection is required against overloads, short circuits and earth faults.
The T5N 400 is supplied in a three-pole, fixed configuration with front terminals, making it suitable for integration into compatible industrial and commercial switchboards. As part of the ABB SACE Tmax family, it combines a compact moulded-case platform with configurable electronic protection for demanding low-voltage distribution systems.

Electronic LSIG Protection for Low-Voltage Distribution
The Ekip E-LSIG trip unit extends the T5N 400 beyond basic overload and short-circuit protection by providing four principal protection functions. Long-time protection responds to sustained overloads, short-time protection supports selective response to short-circuit conditions, instantaneous protection provides rapid operation for severe faults, and ground-fault protection responds to qualifying earth-fault conditions.
Combined with the 400 A T5 frame, three-pole construction, fixed mounting and front-terminal arrangement, these protection functions make the ABB 1SDA081048R1 well suited to compatible feeder and distribution applications where electronic protection and coordination are important design requirements.
Typical Applications
- Main and sub-distribution low-voltage switchboards.
- Industrial feeder protection.
- Manufacturing and process electrical distribution systems.
- Commercial and infrastructure power distribution.
- Three-phase circuits requiring electronic LSIG protection.
- Fixed 400 A distribution and feeder applications.
