Why Choose the ABB 1SDA069620R1 XT4S 250 Ekip E-LSIG 250A 4-Pole Circuit Breaker?
The ABB 1SDA069620R1, designated XT4S 250 Ekip E-LSIG In=250A 4p F F, is a fixed four-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range. Rated at 250 A, it combines the compact XT4 frame with an electronic Ekip E-LSIG trip unit for comprehensive protection of low-voltage power distribution systems.
The integrated Ekip E-LSIG electronic release provides long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection. This combination supports accurate circuit protection and coordination in industrial, commercial and infrastructure distribution systems where dependable protection against multiple electrical fault conditions is required.
This XT4S version has a 690 V AC rated operational voltage, 1000 V rated insulation voltage and 8 kV rated impulse withstand voltage. At 415 V AC, ABB specifies a rated service short-circuit breaking capacity (Ics) of 50 kA, making the breaker suitable for demanding low-voltage distribution applications.
