Applications & Use Cases

The XT4N 250 Ekip Dip LS/I In=250A 3p F F is the preferred choice for engineers designing protection schemes in the following scenarios:

• Transformer Protection: Provides reliable overcurrent and short-circuit protection for LV transformer secondary circuits up to 250 A.
• Generator Protection: Guards generator output circuits against overloads and fault currents in standby and prime power installations.
• Installation Protection: Acts as a main or sub-main breaker in industrial switchboards, MCC panels, and distribution boards.
• High Fault-Level Applications: The 65 kA breaking capacity at 220 V AC makes it suitable for installations close to large power sources where prospective fault currents are elevated.
• Hazardous Area Equipment: ATEX certification permits deployment in Zone 1/Zone 2 classified industrial environments.
