Automatic mains switch - 4P 400V 32A - NLQ4-125/4P for PV

Product detailed description

The automatic grid switch monitors the availability of power from two different sources and switches between them automatically or manually as needed. Ideal for use in systems where power failure is not tolerated. Designed for DIN rail mounting. Main features - Operating mode: - Automatic or manual Installation: - DIN rail mounted - quick and easy installation in a rack Device Features: - Reliable power transfer - Excellent electrical insulation - Easy installation and maintenance - Long service life Application The switch is designed for locations where a continuous power supply is important, e.g.: - Households - Shopping malls - Factories - Laboratories - Agricultural facilities and farms Working principle In the event of an outage or abnormal condition of the main (normal) power supply, it immediately switches to the backup power supply, thus ensuring: - Uninterrupted power supply - Reliable and safe operation - Fast response without failure Design and materials - Housing material: excellent non-flammable PC plastic, resistant to high temperature and aging - Contacts: Silver contacts for excellent conductivity and reliable switching Millisecond switching - Fast response during failure - switching without loss of power - Compact design - Automatic and manual operation possible Technical specifications - Rated operating current: 32A - Rated control voltage Us: AC220 V 50Hz - Normal working condition: 85% Us-110% Us - Rated frequency: 50/60 Hz - Rated voltage: 400V AC - Insulation voltage: 690V AC - Rated short-circuit current: 50kA - Rated impulse withstand voltage: 8kV - Number of poles: 4P - Auxiliary circuit: 2 independent relays, each relay contains 2 sets of transformer contacts - Touch time: <50ms - Operation transition time: <50ms - Return time: <50ms - Off time: <50ms - Electrical lifetime: 2000 - Mechanical lifetime: 5000 - Mounting: on DIN rail - Dimensions (W x H x D): 141 x 104 x 76 mm
