Schaltbau GmbH at the Intersolar in Munich – DC contactor for photovoltaic applications (BILD)

Munich (ots) –

– Cross-reference: Picture is available at –

Again this year Schaltbau GmbH will be at the Intersolar in Munich
(13 to 15 June), showcasing its state-of-the-art DC contactors and
snap-action switches with positive opening feature as well as its
range of connectors. These products are widely used in photovoltaic
applications, in wind turbines and battery storage systems. The
contactors disconnect the solar field from the inverter on the DC
side as main or pre-charging contactors and handle currents from 50
to 1,000 amperes as well as voltages from 1,000 to 3,000 volts.
Further information is available directly at our stand in hall

The CU series of solar contactors made by Schaltbau is the first
to fulfil the European standard EN 60947-3 (tab. 9
„switch-disconnector with fuses“) and is UL-approved. These twin-pole
contactors extinguish electric arcs extremely quickly, minimising
wear on the contacts, making them very long-lasting components. The
contactors have a mechanical working life of two million operating
cycles and an electrical working life of several tens of thousands of
operating cycles, depending on load. Schaltbau’s CU contactors switch
voltages of up to 1.5 or 3 kV and are suitable for currents of up to
1,000 amperes. Apart from having a considerably extended working
life, they are also capable of switching significantly higher
voltages than manual switch-disconnectors. The maintenance-free
contactors can be optionally equipped with an economy circuit that
minimises their power consumption. The small type C294 and C295 solar
contactors are used in various pre-charging applications for lower
voltages (up to 1 kV).

The range of products on display will be supplemented by
connectors and snap-action switches. The charging connectors of the
LV series are used in battery storage systems. The snap-action
switches with positive opening operation in accordance with IEC
60947-5-1, appendix K, are, for example, used as limit switches in
actuators for photovoltaic tracking systems. They are also installed
as auxiliary switches in solar contactors of the CU series.
