Lead-free fuse holder style circuit breaker
May 2006
Electrical Power & Protection
Schurter's new T9 series circuit breaker for equipment is free from lead and other hazardous materials as outlined by the European Union's Restriction of the Use of Hazardous Substances (RoHS). The new design is equipped with the same proven features, such as fuseholder body style, snap-in mounting 16 mm diameter hole and push-to-reset button. Its tripping operation is cycling trip-free.
Fuseholder style circuit breakers are suitable substitutes for panel fuses where inrush currents cause nuisance trips, or ageing of the fusing element over time. Resetting the circuit can avoid unnecessary downtime and maintenance costs associated with replacing fuses. Improper replacement with the wrong current rating is also prevented. The circuit breaker button extends to indicate when the circuit is interrupted. The button returns to depressed status when pushed-to-reset. The ampere rating is clearly visible on the face.
Typical applications include lighting, power tools, industrial appliances, medical diagnostic appliances, UPS, sports and hobby machinery, HVAC. The Schurter T9 series meets UL standard 1077 for Supplementary Protection, CSA C22.2.235, EN 60934 and GB 17701. Current ratings range from 4 to 16 A at 240 V a.c. and 48 resp. 32 V d.c. Terminals are 6,3 mm quick-disconnect.
