FB 3-8.25-00-XX Product Diagram
Featuring an 8.25mm center space (for thick power cables) and a 600V/30A rating, it delivers reliable performance across a -40℃ to 105℃ temperature range—ideal for 3-phase auxiliary circuits, industrial heaters, or large-scale HVAC systems. The "04" in its model denotes a fixed 4-pole configuration (total length: 8.25mm × 4 = 33mm), eliminating the need for modular assembly and reducing installation time. Constructed with UL94 V-0 flame-retardant PA66 insulation (reinforced with glass fiber) and brass terminals (plated with tin for corrosion resistance), it meets IEC 60947-7-1 industrial standards. With a wire range of 22–8 AWG and 8000V surge voltage resistance, the FB 3-8.25-00-XX is a robust choice for applications where fixed pole counts and high current handling are non-negotiable.
Pre-Assembled 4-Pole Design: Total length of 33mm (8.25mm × 4) fits standard 35mm-wide industrial enclosures, common in control panels for 3-phase equipment. No modular assembly is needed—simply mount and wire, reducing installation time by 40% compared to build-your-own pole systems.
Integrated Pole Dividers: Molded PA66 dividers between poles prevent wire contact and short circuits, even in high-vibration environments (e.g., industrial pumps or motor drives). The dividers are reinforced with glass fiber, ensuring they don’t break during wire installation.
600V/30A Rating: Handles high-power circuits, including 3-phase motor control auxiliary lines (480V AC/25A), industrial oven heating elements (240V AC/30A), and large HVAC fan drives (208V AC/28A).
Tin-Plated Brass Terminals: Tin plating enhances corrosion resistance in industrial environments (e.g., factories with dust or humidity) and maintains low electrical resistance—critical for high-current applications where heat generation must be minimized.
8000V Surge Protection: Resists extreme voltage spikes from industrial machinery startups or power grid fluctuations, protecting expensive equipment like variable frequency drives (VFDs) or HVAC controllers.
M4 Steel Screws with Washers: Includes M4 steel screws with integrated washers for wire clamping. The washers distribute pressure evenly across thick wires (e.g., 8 AWG), preventing wire damage while ensuring a tight connection. The screws require 8–10 lbf·in of torque.
Standard Mounting Holes: Fits 4.2mm mounting holes (common in industrial aluminum panels) with M4 mounting screws (not included). The terminal’s base has anti-slip ridges that prevent shifting during installation, ensuring alignment with PCB or panel holes.
22–8 AWG Wire Range: Accommodates thin control wires (22 AWG for sensors) and thick power wires (8 AWG for industrial heaters). The clamping mechanism is designed to fit stranded 8 AWG wires, which are standard in high-power industrial systems.
Temperature & Chemical Resistance: The reinforced PA66 insulation resists oils, greases, and common industrial cleaners, while the -40℃ to 105℃ range withstands extreme factory temperatures (from cold storage facilities to foundries).
Motor Control Panels: Used in 3-phase motor auxiliary circuits (e.g., fan motors, pump drives) to connect power and control wires. The fixed 4-pole design aligns with 3-phase + ground wiring, simplifying panel layout.
Industrial Heaters & Ovens: Integrates into heating element power lines for industrial ovens (e.g., 240V AC/30A ceramic heaters) and heat treat furnaces. The 8000V surge protection safeguards against voltage spikes from heater cycling.
Commercial HVAC Drives: Used in rooftop HVAC units (e.g., 208V AC/28A fan drives) and chiller systems. The fixed 4-pole configuration fits into standard HVAC control panels, while the corrosion-resistant terminals handle humidity in mechanical rooms.
Data Center Cooling Systems: Connects power wires for data center CRAC (Computer Room Air Conditioning) units. The 600V/30A rating handles the high current of CRAC compressors, and the wide wire range accommodates both power and sensor wires.
Food Processing Machinery: Used in large mixers, conveyors, and packaging lines. The reinforced PA66 insulation resists food-grade cleaners, while the UL94 V-0 flame retardancy meets food industry safety standards.
Construction Equipment Auxiliaries: Suitable for portable generators (e.g., 240V AC/25A) and construction tool power distribution. The -40℃ to 105℃ range withstands outdoor construction conditions (from winter cold to summer heat).
The "04" denotes a fixed 4-pole configuration, meaning the terminal comes pre-assembled with 4 poles (total length: 33mm). This is optimized for 3-phase + ground wiring (common in industrial systems) or 4-circuit power distribution—no need to add or remove poles.
Technically yes, but it is overspecified. The 600V/30A rating is designed for industrial use; residential applications (typically 120V/20A) would benefit from a lower-power terminal block (e.g., EMD series) for cost and space efficiency.
Strip 12mm of insulation from the wire (longer than thinner wires to ensure full contact).
Twist stranded 8 AWG wires tightly to prevent fraying.
Tighten the M4 screw to 8–10 lbf·in using a torque wrench—this ensures the washer presses evenly on the wire without damaging the conductor.
