A new disconnect switch from E-T-A aims to meet the growing demand for high-capacity DC disconnects as referred to in standards applicable to photovoltaic systems and fitted between the solar power modules and the power inverters. It features hybrid technology and is the first E-T-A product which has explicitly been designed for the photovoltaic market and its typical DC applications. Its enclosure is DIN rail mountable and suited for installation in distribution boxes.
The electronic control unit will interrupt the circuit, while the mechanical part ensures double pole physical isolation, making this technology suitable for ungrounded systems as well. In addition, the hybrid function allows reliable disconnection in the event of low currents and ensures a low-wear contact system. The hybrid functional principle does not require any additional power supply for the electronic unit.
The switch is rated to 1500 V d.c. and 30 A over the temperature range of -30°C to 60°C. Its modular design allows other versions or status queries. It is also possible to use the product in inverters by means of a modified enclosure or a modified mounting method.
