ETI SSQ 2100 load transfer switch 1-0-2, 2P 100A (2421428)

The ETI SSQ 2100 is a three-position load transfer switch designed for manual switching of electrical circuits in the 1-0-2 positions. It is used in distribution boards, backup power input systems, and other electrical installations where it is necessary to transfer a line between two sources or completely disconnect the circuit. As a load breaker / disconnect switch, this device is intended for operation under load within the limits defined by its utilization category. The unit has 2 poles and is rated for a current of 100 A at an AC voltage of 400 V. The AC-22B utilization category indicates suitability for circuits with mixed resistive and inductive loads, which is typical for distribution networks and the switching of household and commercial consumers. A rated frequency of 50/60 Hz provides compatibility with widely used power systems. Compliance with IEC 60947-3 confirms that the device belongs to the group of switch-disconnectors, disconnectors, and load transfer switches covered by this standard. For conductor connection, the switch is designed for wires up to 50 mm², allowing use in circuits with comparatively high current demand. The IP20 protection rating means protection against access to hazardous live parts by a finger or similar objects, so the device is intended for installation inside electrical enclosures and distribution boards. This should be considered when selecting the mounting location and designing the switchboard layout. The SSQ 2100 series is suitable for use as a main or auxiliary switching device in industrial, commercial, and residential electrical systems where clear three-position switching without automatic tripping is required. Its two-pole design, 100 A rating, 400 V AC operating voltage, and standardized construction make it suitable for circuit control and power distribution applications.
