1SDA100734R1 ABB XT6N 800 Ekip Dip LSI 4-Pole Circuit Breaker

Why Choose the ABB XT6N 800 Ekip Dip LSI 1SDA100734R1 Circuit Breaker?

The ABB 1SDA100734R1 is a high-performance four-pole moulded case circuit breaker (MCCB) designed for dependable protection and isolation in industrial and commercial low-voltage power distribution systems. Part of the proven ABB SACE Tmax XT series, this XT6N 800 model combines a fixed mounting arrangement, front terminals and an electronic Ekip Dip LSI trip unit for comprehensive circuit protection.

Rated at 800 A, the XT6N is engineered for demanding electrical distribution applications where reliable overload and short-circuit protection is essential. Its Ekip Dip LSI electronic trip unit provides long-time, short-time and instantaneous protection functions, allowing the breaker to protect cables, switchboards and connected equipment against a range of overcurrent and fault conditions.

The XT6N performance level provides a rated ultimate short-circuit breaking capacity of 36 kA at 415 V AC. Its four-pole configuration, fixed installation format and front-connected terminals make the 1SDA100734R1 well suited to switchboards, distribution panels and industrial power systems requiring a robust high-current protection solution.

Reliable Protection for Low-Voltage Power Distribution

Moulded case circuit breakers such as the ABB XT6N protect electrical distribution systems against overloads and short circuits while also providing circuit switching and isolation. The Ekip Dip electronic trip unit monitors current and trips the breaker when configured protection thresholds are exceeded, helping minimise damage to conductors, switchgear and connected equipment.

The LSI protection functions make this model particularly suitable for distribution systems where greater protection selectivity and coordination are required. Long-time protection responds to sustained overload conditions, short-time protection supports coordination during short-circuit events, and instantaneous protection provides rapid operation in response to severe fault currents.

Typical Applications

• Industrial low-voltage switchboards and distribution panels.
• Main incoming and feeder circuit protection.
• Commercial building electrical distribution systems.
• Manufacturing and process plant power distribution.
• Transformer and installation protection applications.
• Protection of high-current cables and electrical distribution equipment.
