Rice Lake UJB3T6 DC Transient Protector | Six-Wire Load Cell Surge Protection

The Rice Lake UJB3T6 DC Transient Protector is a heavy-duty surge protection system designed to safeguard load cells, strain gauge transducers, and serial communication lines from damaging voltage transients and electrical surges. Built for industrial weighing applications, truck scales, tank scales, hopper scales, and harsh outdoor environments, the UJB3T6 helps protect sensitive weighing equipment from lightning-induced surges, electrical disturbances, and power fluctuations that can lead to costly downtime and equipment failure. The unit can protect up to six data lines or up to eight parallel or summed load cells, making it an ideal solution for demanding weighing installations.

Designed with a full six-wire protection system and separate shield circuitry, the UJB3T6 provides comprehensive protection while maintaining signal integrity for highly sensitive weighing applications. It is compatible with signals down to 1 μV per graduation, ensuring accurate performance in precision weighing systems. Fast transient response times of less than 100 nanoseconds help divert harmful voltage spikes before they reach connected equipment.

The factory-serviceable design allows easy maintenance and long-term reliability in the field. Its #6 SEMS screw terminals accept spade lugs, tinned leads, or bare wires up to #12 AWG, simplifying installation and wiring. The included 20-foot insulated #10 AWG grounding wire helps ensure proper grounding for maximum surge protection effectiveness.

Built for harsh industrial environments, the UJB3T6 is housed in a rugged NEMA Type 4X fiberglass-reinforced polyester (FRP) enclosure capable of withstanding washdown pressures up to 40 PSI. The enclosure includes two nylon strain-relief fittings for cable protection and features an anti-fungal coated circuit board for enhanced durability in humid and corrosive environments.

Whether installed in truck scale systems, industrial process weighing applications, manufacturing facilities, or outdoor weighing stations, the Rice Lake UJB3T6 DC Transient Protector delivers dependable protection that helps extend equipment life, improve system reliability, and reduce maintenance costs.
