MECHANICAL AND ELECTRONIC CONTROLTHERMAL CUTOFFG4 MICROTEMP ® thermal cutoffMICROTEMP ® thermal cutoffs offer an accurate, reliable solution to the need for upper limittemperature protection. MICROTEMP ® thermal cutoff provides protection against overheatingby interrupting an electrical circuit when operating temperatures exceed the rated temperatureof the cutoff. Temperature range 72 to 240ºC. One-shot operation cuts off electrical power.Current interrupt capacity up to 10 Amp at 250 VAC. Low resistance. Compact size. Rated forcontinuous operating currents up to 10 Amp at 250 VAC, the G4 series MICROTEMP ® TCO isthe industry standard for over-temperature protection.Article number Type UnitOn request G4 MICROTEMP ® 2000121G5 MICROTEMP ® thermal cutoffMICROTEMP ® thermal cutoffs offer an accurate, reliable solution to the need for upper limittemperature protection. MICROTEMP ® thermal cutoff provides protection against overheatingby interrupting an electrical circuit when operating temperatures exceed the rated temperatureof the cutoff. Temperature range 72 to 240ºC. One-shot operation cuts off electrical power.Current interrupt capacity up to 16 Amp at 250 VAC. Low resistance. Compact size. Designedfor higher current applications, the G5 series MICROTEMP ® TCO is rated for operating currentup to 16 Amp at 250 VAC. The G5 series has a different internal construction designed forinterrupting higher currents.Article number Type UnitOn request G5 MICROTEMP ® 2000G7 MICROTEMP ® thermal cutoffMICROTEMP ® thermal cutoffs offer an accurate, reliable solution to the need for upper limittemperature protection. MICROTEMP ® thermal cutoff provides protection against overheatingby interrupting an electrical circuit when operating temperatures exceed the rated temperatureof the cutoff. Temperature range 72 to 240ºC. One-shot operation cuts off electrical power.Current interrupt capacity up to 5 Amp at 250 VAC. Low resistance. Compact size. Designedto satisfy applications requiring miniaturized components that do not need maximum currentinterrupt capability. The G7 is just 2/3 the size of the G4 and G5, and with a current interruptingcapability of 5 Amp at 250 VAC, it is capable of meeting the requirements of transformers, motors,battery packs and electronic circuit applications.Article number Type UnitOn request G7 MICROTEMP ® 2000IMICROTEMP ® TCO Operating Temperature SummaryMax. open temp.
