Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The 140M-C2E-C20 is the device-level element in an Allen-Bradley circuit breaker installation. It receives the field signals and control supply listed above — <= 440 V AC — and switches or conditions the load within the <= 440 V AC ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in distribution boards, motor protection circuits, panel feeders, where the unit is matched to the original catalog number and the enclosure provides 35 mm DIN rail (IEC 60715) support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Allen-Bradley 140M-C2E-C20 — Circuit breaker providing branch-circuit overload and short-circuit protection in distribution boards and panel feeders. The figures below are taken from the specification table on this page for catalog number 140M-C2E-C20; record the nameplate data of the unit being replaced before selecting an equivalent.
For a discontinued unit, match function and electrical ratings rather than the label alone.
Q.Which value is published under operating temperature for catalog number 140M-C2E-C20?
For 140M-C2E-C20, operating temperature is given as -25...+60 °C. Check the revision of the installed unit if the catalog number has been superseded.
Q.Before ordering 140M-C2E-C20, which rated impulse withstand Uimp entry should be checked?
