The GE THED136040 is a three-pole circuit breaker rated for 40 amperes and designed for electrical systems up to 600 volts, providing robust overcurrent protection for three-phase feeders in commercial and light industrial installations, where reliable interruption of fault currents is essential. Manufactured by General Electric, this THED-series device is identified by model THED136040 and features a green housing that helps distinguish its line and family within control panels. With three poles in a single frame and a 40 A rating, it serves to protect three-phase circuits from overloads and short circuits in electrical panels. The unit is clearly labeled 'THED136040' and finished in green, helping installers verify the correct GE THED model during maintenance or replacement tasks. With a 600 V maximum rating, it is intended for use in three-phase electrical systems that operate at or below this voltage limit.
