UL486A-B Table 26 Wire Damage Testing Device Screw Terminals Mechanical Stress Test
Product Information:
This testing device conforms to UL486A-B clause 9.3.2.1, clause 9.3.2.3, clause 9.3.2.4 and table 26 and figure 6, IEC60947-1, etc.
Specimens and restrictions: Screw terminals, threadless terminals and connectors.
Test purpose: To examine whether the screw terminals and threadless terminals can withstand the mechanical stresses that occur during normal use. It is mainly used to judge whether the design and structure of the thread clamping terminal block meet the requirements of not excessively damaging the wire when clamping the wire.
Testing principle: Using guide rail screw structure. The number of tests can be preset before use. When the set value is reached, the machine will automatically stop and sound an alarm signal.
