The HGN4-002GL 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, mean that they are ideally suited to be used in the switching of Photovoltaic (PV) systems. Key Features P65 rated enclosure TUV Approval Ample internal space for easier wiring. Polycarbonate flame retardant plastic ,UV protect 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, 20pcs/carton
