T9 series

In addition to its existing snap-in front panel mount version, Schurter AG offers the fuseholder-style, single-pole thermal circuit breaker series T9 with threaded-neck and snap-in versions for rear mounting. The threaded-neck type is available with an IP 65 rated cover, which provides protection against environmental conditions such as dust or jetting water. Its tripping operation is cycling trip-free.

Circuit breakers with the fuseholder style body are ideal substitutes for panel fuses where inrush currents cause nuisance trips or aging of the fusing element overtime. 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.

Typical fields of application include power supplies, UPS, PDUs, power tools, industrial appliances, medical diagnostic and analysis appliances, lighting, sports and hobby machinery or HVAC. The T9 series of Schurter meets UL standard 1077 for Supplementary Protection, CSA C22.2 235, IEC 60934 and GB 17701. Current ratings range from 4 - 16 A at 240 VAC and 48/32 VDC.
