UL486A-B Table 26 Wire Damage Testing Device Screw Terminals Mechanical Stress Test
Products Description
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.
Technical Parameters:
1. The centering locking fixture meets the requirements of terminal blocks with length, width and height of 60*70*90mm respectively. The fixture has the characteristics of quick replacement.
2. Equipped with additional mounting plate, size 300mm*250mm, which can be used interchangeably with the centering locking clamp.
3. The maximum distance between the mounting plate and the rotation center is 120mm, adjustable
5~15 rpm, can be preset on the touch screen,
(UL486A-B requires 9 rpm)
1. 0-999999, it will automatically stop when the preset number of tests is reached.
2. The test time can be switched to 0-9999min according to different standard requirements, and can be preset. It will automatically stop when the preset test time is reached.
