Abstract (en)

[origin: EP0579170A2] A resistor (10) comprising a tubular sheath (11) for protecting the resistor and heat-sensitive switching means for protection against overheating. These means include normally-closed fixed and movable contacts (22a, 24a, 26a, 26b) and pusher elements (27) for the quick opening of the contacts. The pushers are controlled by respective pre-loaded elastic means (33) normally kept under tension by traction elements (31) which are rigidly coupled by stop elements (34) made of fusible material which are associated with the sheath (11). When a preset sheath temperature is exceeded, the stop elements (34) melt and release the pre-loaded elastic means (33) opening the contacts. <IMAGE>
