RH RY Series
*TF - Rated functioning temperature:
Temperature of the thermal-link which causes it to change its state of conductivity with a detection current up to 10mA as the only load. .
*Fusing-off temperature
The fusing-off temperature indicates value measured in the test oil bath and temperature be increased steadily with a rate of rise between 0.5K/min to 1K/min and detective current 0.1 ampere or less.
*TH – Holding temperature
The maximum temperature at which a thermal-links will not cause a change in state of conductivity to open circuit while conducting rated current for 168 hours or according to IEC60691.
*TM – Maximum temperature limit
Temperature of the thermal-link stated by the manufacturer, Up to which the mechanical and electrical properties of the thermal-link, Having changed its state of conductivity ,Will not be impaired for a given time.
Fuse
Device that, by th fusing of one or more of its specially designed and proportioned components, opens the circuit in which it is inserted by breaking the current when this exceeds a given value for a sufficient time.
miniature fuse
Fuse in which the fuse-link is a miniature fuse-link.
Fuse-link
Part of a fuse including the fuse-element(s) intended to be replaced after the fuse has operated.
Miniature fuse-link
Enclosed fuse-link of rated breaking capacity not exceeding 2KA and which has at least one of its principal dimensions not exceeding 10mm.
Sub-miniature fuse-link
Miniature fuse-lnk of which the case (body)has no principal dimension exceeding 10mm.
Fuse-holder
Combination of a fuse-base whith its fuse-carrier.
