ABB 1SFL637025R6911

The GAF750-10-11 contactor is a 3-pole device tailored for DC-1 applications, enabling all three poles to be connected in series with a maximum voltage rating of 1000 VDC. It operates over a wide control voltage range of 48-130 V for both AC and DC applications.

Key specifications include a rated operational current of 1050 A at 1000 VDC for ambient temperatures up to 40 °C, with reduced ratings at higher temperatures. The contactor features a mechanical durability of 3 million cycles and can handle a maximum mechanical switching frequency of 300 cycles per hour.

This model also adheres to stringent environmental standards, being operational in ambient temperatures from -40 °C to +80 °C and capable of withstanding altitudes of up to 3000 m without derating. Its degree of protection is defined by IEC standards, ensuring reliable operation in various conditions.

Furthermore, the contactor supports connecting capacities for both main and auxiliary circuits, accommodating a range of cable sizes. The terminals for the main circuit are designed for bars, enhancing connectivity options. The design aligns with multiple certifications, including compliance with RoHS and REACH directives.
