T9-817 Series Circuit Breakers

SCHURTER's T9 fuse holder style thermal circuit breaker series is now expanded to include a version for vertical PCB-mounting. The vertically mounted model completes the existing range, which also includes a horizontal PCB-mount version, and three different panel-mount styles with quick connect terminals: snap-in or nut fastened, including a threaded neck, rear-mount style. The full range provides a form and fit alternative to equivalent closed fuse holders

The T9-817 PCB mount circuit breaker reduces assembly costs and saves board space, by eliminating assembly hardware and wires. It sports a slim design and a small push-to-reset cylindrical button, which protrudes minimally through the panel opening. A spring pushes the button out further when the device trips.

Circuit breakers are an ideal alternative to fuses since fuses are known to age due to pulse- or high-surge currents and thus trip prematurely. Circuit breakers prevent unnecessary down-time by eliminating the need for fuse replacement, as well as the associated risk of inadvertently inserting a fuse with the incorrect current rating. The T9 series thermal circuit breaker is therefore intended as an alternative to 5 mm x 20 mm or 6.3 mm x 32 mm fuses used with closed fuse holders.

Typical applications for circuit breakers include power supplies, UPS systems, PDUs, electric tools, motor drive applications, medical diagnostic equipment, commercial kitchen appliances, lighting fixtures, and HVAC products, as well as equipment for sports and leisure activities. The T9 series is also available on request with glow-wire tested (GWT) materials and is therefore suitable for unattended household appliances. The T9 product line conforms to UL 1077, CSA C22.2 235, and IEC 60934 standards. It is cURus, VDE and CCC approved.
