ALLNET ALL-BRICK-0504 5 Ohm 400W Power Resistor, Aluminum Housing, Chassis Mount, Screw Terminals, IP54

The ALLNET ALL-BRICK-0504 is a high-power wirewound resistor designed for demanding industrial applications. With a resistance value of 5 Ohm and a power rating of 400 W, it is ideal for braking systems, load testing, and inverter circuits. The robust aluminum housing provides excellent heat dissipation via convection cooling, while the IP54 rating ensures protection against dust and water splashes. Chassis mount design with screw terminals allows for secure and easy installation.

Advantages

High power handling capacity in a compact form factor. The aluminum housing acts as a heatsink, enabling reliable operation without active cooling. The ±5% tolerance and ±50 ppm/°C temperature coefficient ensure stable performance across a wide temperature range. Dielectric strength of 2.5 kV and insulation resistance >100 MΩ guarantee safety and longevity.
