The 2TC2 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 2TC 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 2TC 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.
Includes hardware.
This 2TC2 series circuit breaker (Alternate Part# 2TC2-3) has a 3 ampere rating.
Features:
- Miniature size
- Light weight
- Trip-free design
