T9-818 data sheet - .PDF file.

Schurter’s T9 fuse-holder-style circuit breaker series has been expanded to include the T9-818 model for PCB mounting. The new model complements the existing T9 series assortment for panel mounting, providing a complete range of mounting styles equivalent to closed fuseholders.

The T9 series features dimensions comparable to those of traditional fuse holders and is likewise similarly designed for direct placement on circuit boards. 

As with all PCB-mounted components, assembly costs are considerably lower because fewer materials are used and wires are eliminated to fully automate assembly. In addition, the T9-818 is more compact than quick-connect terminal types and thus requires less space. Furthermore, its slim design means the reset button protrudes only minimally from the front panel. Two mounting pins provide additional mechanical support on the circuit board and protect the solder connections from additional pressure when the reset button is activated.

The shape of the T9 circuit breaker is similar to that of a fuse holder and thus is said to offer an excellent alternative to 5×20 fuses and their respective fuse holders, where current surges can lead to premature tripping and ageing over time. In contrast, circuit breakers prevent unnecessary downtime by eliminating the need for changing fuses, as well as the associated risk of inadvertently inserting a fuse with the incorrect current rating, which may lead to equipment damage.

A further advantage of circuit breakers is the reset button, which springs out to indicate when the device trips. Reset is achieved by a simple push of the button. Typical application areas for circuit breakers include power supplies, UPS systems, PDUs, electric tools, industrial applications, medical diagnostic equipment, analysis systems, lighting fixtures, HVAC products and equipment for sports and leisure activities.
