The hgn4-003gl dc isolators have been specifically designed to switch direct current (dc) at voltages up to 1000volts. Their robust design and ability to switch such voltages, at rated current, means that they are ideally suited to be used in the switching of photovoltaic (pv) systems. The product adopts the latest opposed wiring mode, which is different from the cross dislocated wiring of the previous similar products(hgn4-002gl). Therefore, it is more convenient for the electricians to assure the correct wiring, and to avoid to make error for the wiring of the input and output. Key features ample internal space for easier wiring. 16a, 25a & 32a all rated up to 1000v dc. unique spring loaded switching mechanism for high speed switching(5ms max). knife edge self-cleaning contacts for increased switch life. long arc chambers to help rapid arc suppression 16mm2 rising clamp terminals for easy wiring. 1pc/inner box, 60pcs/ carton
