ETI SSQ 125 load switch 1-0-2, 1P 25A (2421414)

ETI SSQ 125 is a single-pole load switch designed for manual switching of electrical circuits in the 1-0-2 position scheme. Such a configuration allows the circuit to be transferred between two power sources or disconnected by moving it to the neutral “0” position, which is useful during maintenance and service operations. The device is intended for use in distribution boards, reserve power systems, and other electrical installations where clear manual switching is required without automatic control logic. The switch is rated for a current of 25 A and operates at a nominal AC voltage of 230 V. This makes it suitable for single-phase circuits where controlled load transfer and circuit isolation are needed. Support for 50/60 Hz ensures compatibility with common AC network frequencies. The single-pole design is appropriate for compact applications and straightforward connection in low-voltage switchgear. According to standard 60947-3, the device belongs to low-voltage switching apparatus intended for switches, disconnectors, and load break switches. This standard confirms its use in electrical systems where switching under load and safe disconnection are required within the declared operating parameters. The IP20 degree of protection indicates protection against finger contact with live parts, so the unit is designed for installation inside electrical enclosures, switchboards, and control cabinets with additional external protection. For conductor connection, the switch accommodates wires with a cross-section of up to 16 mm², which simplifies integration into typical power circuits in electrical panels. The SSQ 125 series is used in applications where manual source selection or line disconnection must be carried out in a controlled manner. ETI load switch 1-0-2 is therefore suitable for residential, commercial, and technical installations, particularly where reliable circuit transfer between two sources and a zero position are needed within a low-voltage distribution system.
