This Schurter Inc. TA45-ABFYSJ19C0-AZM01 is a thermal circuit breaker designed for equipment protection. It operates with a rated voltage of 240 VAC and 60 VDC, and has a current rating range of 0.05 to 20 A, with this specific model rated at 1.9A.
The breaker is a 2-pole unit with rocker actuation and a snap-in panel mount. It offers a conditional short circuit capacity of 1 kA at 240 VAC and a short circuit capacity Icn of 300A at 240 VAC for currents 3A or greater. The degree of protection is IP40 on the front side, increasing to IP54 with a factory-mounted protection cover.
Key electrical specifications include a dielectric strength of 4 kVAC and an insulation resistance greater than 100 MΩ at 500 VDC. Mechanical lifetime is rated for 50,000 switching cycles, with AC and DC lifetimes also at 50,000 cycles at 1x Ir. Overload performance is specified as a minimum of 40 trips at 6x Ir for AC and 4x Ir for DC.
Environmental considerations include an allowable operating temperature range of -10 °C to 55 °C and a storage temperature range of -10 °C to 55 °C. It meets vibration resistance standards per IEC 60068-2-6 and shock resistance per IEC 60068-2-27. The tripping type is thermal.
