Part 3TC12-30

Description

The 3TC12 series single-phase circuit breakers provide reliable state-of-the-art circuit protection for aerospace power systems. The compact and lightweight design makes these circuit breakers well suited for aircraft avionics and electronic systems. The 3TC series ratings is coordinated so any rating will trip before another rating twice its capacity in the event of a fault. Ambient temperature compensation allows the 3TC circuit breakers to operate where temperatures exceeds the 160°F maximum of non–ambient compensated thermal circuit breakers and may also operate in temperatures as high as 150°F without derating the circuit breaker while eliminating the need for added cooling.  The 3TC circuit breakers are available in 15 to 35 amperes. Includes hardware. Features This 3TC12 circuit breaker is rated for 30 amps. Compact size and weight Trip-free design 1 to 25 Amp current rating High vibration resistance High interrupting capacity up to 6,000 amps at 28 VDC and 3,500 amps at 120 VAC, 400 Hz Typically used on aircraft power distribution systems AS58091 qualified as well as military approvals, and FAA PMA Specifications Weight: 36 g, maximum Dimensions: 1.1 x 0.781 x 1.249 mm, max.
