Barrier terminal block is used in electrical and electronic engineering industries: lighting, elevators control, instrumentation, power, chemical and automotive power, etc. For its safe, reliable, effective connection, barrier terminal blocks are widely applied under the high current, high voltage environment. There are two basic types of barrier terminals: UL and IEC. The rated voltage and rated current under UL standard are 300v, 15A, and the electrical performances under IEC standard are 250V, 24A.
The spacing of barrier terminal block usually is 7.6mm and the number of poles ranges from 2~26P. Most parts of barrier terminal block are made of brass and the maximum locking torque is 0.5N.m 4.4Lb.in. Because of barrier terminal's material mechanical properties and measurements, it can be applied on a maximum temperature at 105℃ and a minimum temperature at -40℃. All the features make barrier terminal block get a huge market in the future.
