Product Introduction   
HGN4-004GL 1000V DC Switch Disconnctor for Photovoltaic

Application
The HGN4-004GL 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.
The HGN4-004GL DC switch achieves ultra-rapid switching through a patented ¡®Snap Action¡¯ spring driven operating mechanism. When the front actuator is rotated, energy is accumulated in the patented mechanism until a point is reached at which the contacts are fired open or closed. This system will operate the switch under load within 5ms thereby reducing the arcing time to a minimum.
In order to reduce the chances of an arc propagating, the HGN4-002GL switch employs rotary contact technology. This is designed to make and break the circuit through a revolving double break contact assembly that wipes as it moves. The wiping action has the added advantage of keeping the contact faces clean thereby reducing the circuit resistance and increasing the life of the switch.
The HGN4-004GL boxed DC isolators are manufactured from flame retardant polycarbonate plastic resulting in an extremely strong, reliable, safe switch. They are also supplied in an enclosure which gives plenty of space for cabling.
 
Key Features
TUV Approval
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
The switch has 4 separate poles.
Links can be used to change the way that the poles are connected.
Poles can be connected in series parallel or a variation of both series and parallel.
Interconnection of the poles dictate the load that the switch can make and break.
As the number of poles increased so the total load switching capacity of the device increases.
 
 All Photo Voltaic installations must have a DC Switch to disconnect the DC/AC inverter from the photovoltaic panels in accordance with IEC 60364-7-712 as illustrated.
