## Long description

The Pollin WN-3B is a professional 3-phase modular indicator light designed for efficient monitoring of electrical circuits. Engineered for standard DIN rail mounting, this device provides reliable visual status feedback through a bright red LED indicator. It features an integrated fuse holder compatible with standard 5x20mm fuses, ensuring both monitoring and circuit protection in a single compact unit. With an operating voltage range of 10-250V AC, it is a versatile solution for various electrical distribution environments.
Advantages
The primary advantage of the Pollin WN-3B is its space-saving modular design, which allows for seamless integration into existing DIN rail setups without requiring additional panel space for separate fuse holders. The inclusion of a 100mA fuse holder adds a layer of safety by protecting the indicator circuit itself. Its wide voltage compatibility makes it highly adaptable for different industrial and residential applications, while the high-visibility red LED ensures that the status of each phase is easily identifiable at a glance.
Suitable for
Monitoring 3-phase electrical distribution boards
Industrial control panels and automation systems
Residential electrical installations
Visual status indication for individual phases
This device is not suitable for DC circuits as it is specifically designed for AC voltage applications. It should not be used in environments where the required fuse rating exceeds 100mA, as the integrated holder is calibrated for this specific current limit.
Key specifications
Voltage range: 10-250V AC
Indicator color: Red
