Product FAQs
8 answers
What is the adjustable thermal trip range for the 140M-C2E-B25?
The thermal overload protection on this motor protection circuit breaker can be adjusted between 1.6 and 2.5 Amps.
What is the fixed magnetic trip threshold for this breaker?
The magnetic short-circuit trip is fixed at 33 Amps, which is approximately 13 times the maximum operational current.
What trip class does the 140M-C2E-B25 feature?
This breaker features a Class 10 trip mechanism for reliable motor overload protection.
Is the Allen Bradley 140M-C2E-B25 still in active production?
No, this model was discontinued by Rockwell Automation in February 2022. The direct engineering replacement is catalog number 140MT-C3E-B25.
Which auxiliary contacts are compatible with this C-Frame breaker?
It accepts standard 140M-C frame accessories, including front-mounted contacts like the 140M-C-AFA10 or 140M-C-AFA20, and side-mounted contacts like the 140M-C-ASA11 or 140M-C-ASA20.
What are the physical dimensions and frame size of the 140M-C2E-B25?
This is a Frame C device measuring 45mm wide, 90mm high, and 74.5mm deep. It is designed for standard 35mm DIN rail installation in high-density control panels.
Does this breaker provide phase loss protection?
Yes, the 140M-C2E-B25 incorporates phase loss protection along with current limiting capabilities and thermal-magnetic trip functions to safeguard 3-phase motors.
Is the 140M-C2E-B25 rated for Type 1 or Type 2 coordination?
It provides Type 1 coordination standard and can achieve Type 2 coordination at up to 50kA at 480V, ensuring the motor starter remains operable after a fault.
