Fuse module LB4P/4x1.5A/FTA AWZ533

Fuse module – independent power supply and circuit protection

This fuse module, designated LB4P/4×1.5A/FTA, is a compact solution for power distribution in low-voltage systems. It allows you to split a single power source into four independent circuits, providing protection for each against overload and short circuit. It will be useful in CCTV installations, alarm systems, and other applications requiring independent power supply for several devices.

Construction and functionality

The module accepts input voltage in the range of 10-24V AC or 10-30V DC, making it versatile in use. Each of the four outputs provides a current of up to 1.5A. The outputs are galvanically isolated, which increases the safety and reliability of the system. Built-in SCP (short circuit protection) and OLP (overload protection) protect both connected devices and the module itself. Additional overvoltage protection with varistors increases resistance to interference in the power supply network.

Optical signaling with LEDs informs about the status of each output – lighting up the LED indicates a blown 1.5A fuse. This facilitates quick identification of a faulty circuit and minimizes system downtime. Module mounting is simple and convenient – it can be mounted on a mounting rail or glued with adhesive tape. Compact dimensions (100 x 20 x 43 mm) allow installation in a limited space. Wires are connected using screw terminals with a cross-section of 1mm².

Applications

The LB4P/4×1.5A/FTA module is ideal for:

• Powering CCTV cameras – protects against damage to one device without affecting the operation of the remaining cameras.
• Powering alarm sensors – provides independent power supply for each sensor.
• Home automation systems – allows power division to various control circuits.
• Protection of electronic devices – protects against damage caused by overvoltage or short circuits.
• Power separation in CCTV and DSS systems
• Applications requiring independent power supply for several current receivers.
