Battery Disconnect Switch

Characteristics

• Rated load value: DC 48V, 300A (can be switched on and off with load); non-load switching can reach DC 80V, 300A.
• IP67 protection rating, waterproof and dustproof.
• A rotation angle of 90° ensures reliable contact and disconnection of the switch points, making it easy to identify the position of the switch.
• Products with an ending number 'H' are equipped with magnetic blow-off attachments, capable of carrying a load with a switching capacity of up to 90V and 200A.
• Products with a suffix of G are equipped with an auxiliary switch that connects and disconnects simultaneously with the main circuit. The lead length can be customized according to customer requirements.
• Type A can be locked in the OFF position; Type B can be locked in both the ON and OFF positions.

Working Principles

• 1.When the handle is rotated 90° clockwise, the drive shaft pushes the contact piece to connect with the terminal, closing the current circuit of the two terminal posts.
• 2.When the joystick is rotated 90° counterclockwise, the spring force of the transmission shaft retracts, causing the current to disconnect at the two terminal posts.
• Circuit Connection Instructions
• 1.Connection of the power supply positive terminal: The disconnection point is located between the power supply and the load. When the switch is turned off, it disconnects all power to the load.
• 2.Connection of the power supply negative terminal: The disconnection point is between the power supply and ground. When the switch is open, there may be a potential short-circuit current between the load and the ground.

• Precautions for Use
• ※ To enhance anti-interference capability, products with auxiliary contacts (designated by a suffix 'G') should pay attention to the differentiation of positive and negative polarity of the main contact terminals during installation.
• ※ The torque range for tightening the screws is specified below; exceeding the maximum torque value may lead to product rupture.
• 1）Contact terminal tightening torque: 17-24 N·m
• 2） Torque at the installation location (for 2×M8 bolts): 24 N·m (maximum)
• ※ Do not allow debris and oil stains to contaminate the main terminals, and ensure that the external terminal connections make reliable contact with the product's main terminals; otherwise, this may cause the terminals to overheat significantly. Additionally, the connecting lead cables must meet the required cross-sectional area to prevent overheating, which could affect the product's lifespan.
