Product Description

Compact Overcurrent Protection for Control and Auxiliary Circuits in Car Wash Cabinets

The F&F BZ-3 triple-socket fuse module is a professional solution designed for DIN TH-35 rail mounting in technical control cabinets and distribution boxes. Housed in a compact enclosure measuring just 1 module (18 mm width), it incorporates three independent protective channels. For proper operation, the module requires three dedicated 5x20 mm glass tube fuse links (the matching glass tube fuse link 20x5mm 200mA WKŁ-BEZ-RUR is recommended). The module allows protection of AC/DC circuits rated up to 250 V with a maximum load current of 6.3 A per channel. Each of the three channels features a clear red LED indicator that instantly illuminates upon fuse blown status. Looking for additional electrical or automation components? Explore our full catalog of car wash spare parts.

Key Features & Technical Specifications of the F&F BZ-3 Module:

  • Three Independent Channels in 1 Module: Space-saving modular housing (18 mm wide) optimizes DIN rail space while organizing overcurrent protection for multiple auxiliary circuits or loads. Requires 3 cartridge fuse links (product code: WKŁ-BEZ-RUR).
  • Optical Blown-Fuse Indicator (LED): A dedicated red LED for each socket lights up when the internal fuse blows (operating voltage range 160–250 V AC/DC), enabling immediate visual troubleshooting.
  • Standard O5x20 mm Fuse Holders: Screw-in cap design allows quick and safe replacement of glass tube fuses using a flathead screwdriver without removing the module from the rail. Check out the compatible 5x20mm fuse link WKŁ-BEZ-RUR.
  • Durable 2.5 mm2 Screw Terminals: Heavy-duty screw clamps accommodate solid and stranded wires up to 2.5 mm2 cross-section (recommended tightening torque: 0.4 Nm).
  • Wide Operating Temperature Range: Built to operate reliably in harsh technical environments ranging from -25°C to +50°C. Learn how to prevent winter electrical issues in our winter car wash preparation guide.
  • High Flammability Rating (UL94 V0): Constructed from grey thermoplastic material with a UL94 V0 flammability class for high fire safety standards. Discover more maintenance insights in our article on car wash maintenance tips.

Frequently Asked Questions (FAQ)

Which fuse links are compatible with the F&F BZ-3 module and how many are required?
The module requires three fuse links to operate. It uses standard 5x20 mm (O5x20 mm) glass or ceramic cartridge fuses rated up to 6.3 A per channel, such as the recommended glass tube fuse link WKŁ-BEZ-RUR.
How does the LED blown-fuse indicator work in the BZ-3 module?
When a fuse blows, the red LED connected in parallel across the fuse holder illuminates (operating within 160–250 V AC/DC), instantly highlighting the faulty channel on the cabinet rail.
How much DIN rail space does the BZ-3 fuse module occupy?
The module features a standard 1-module width (18 mm), saving valuable space on the DIN TH-35 rail while offering 3 separate fused channels.
How are glass tube fuses replaced in this module?
Fuse replacement is simple and safe: unscrew the front black cap using a flathead screwdriver, replace the blown 5x20 mm fuse (WKŁ-BEZ-RUR), and screw the cap back in place.
What are the maximum electrical ratings for the BZ-3 module?
The maximum operating voltage is 250 V AC/DC, and the maximum load current is 6.3 A for each of the three channels.
