Mechanical Performance
The terminal shall withstand 4 bends of 90°rotation without any breakage or damage, when the Resistor is fixed in vertical position.
Fixing the resistor body, a static load of 2.5Kg is to be gradually applied into the terminal for 10seconds without causing any looseness and fall.
To bend the lead wire at the point of about 6mm from resistor body to 90°,then catch the wire at 1.2±0.4mm apart from the bend point end and turn it (clockwise) by 360 degrees Perpendicular to the resistor axis at speed of sane 5 seconds per turn, and do the same Counterclockwise again which constitute a whole turn. Repeat the turn for 2 times without Causing any break and looseness.
Description
Thermal fuses, defined as non-resettable, are single action devices that are widely used for the electrical equipments against over temperature. The thermal cutoffs are composed of the fusible alloy with low melting point and special resin, encapsulated in a plastic or ceramic housing. Under normal operated, the fusible alloy is joined by the two lead wires within the housing. When the thermal cutoff senses an abnormal heat and reach a preset temperature, the fusible alloy melts and disconnects the circuit completely with the aid of the special resin. Both Axial and Radial shapes are available, with rated current from 1A to 200A, Function temperature 76℃~221℃, certificated including UL, cUL, VDE,TUV,PSE, KTL, CCC and RoHS, REACH Compliant.
