ETI SSQ 180 load changeover switch 1P 80A 1-0-2 (2421417)

ETI SSQ 180 is a three-position load changeover switch designed for manual switching of electrical circuits in the 1-0-2 scheme. It is used in distribution boards and power installations where it is necessary to transfer supply between two lines or completely disconnect a circuit in the neutral position. Such functionality makes the device suitable for reserve power circuits, source selection, and load distribution tasks. The model has one pole and is rated for a current of 80 A at 230 V AC. It operates at a nominal frequency of 50/60 Hz, so it can be used in common single-phase alternating current networks. The AC-22B utilization category indicates application for switching mixed resistive and moderate inductive loads, which is typical for many household and commercial circuits. This allows the switch to be used where controlled manual switching is required without automatic functions. The device supports connection of conductors with a cross-section up to 50 mm², which is important for power circuits with larger cable dimensions. Protection degree IP20 means the switch is intended for installation inside an electrical enclosure or other protected mounting system, where accidental contact with live parts is prevented by the cabinet design. The product complies with IEC 60947-3, the standard covering switches, disconnectors, and load-break switches. SSQ 180 combines the 1-0-2 operating logic with a compact single-pole design, making it a practical solution for engineering systems that require clear and predictable circuit commutation. It can serve as a load switch or isolating switch in systems where switching between two power paths must be performed manually and with defined positions.
