Information About 140-CMN-9000
The 140-CMN-9000 is part of the Bulletin 140 Motor Protection Circuit Breaker by Allen-Bradley. This electrical device is one of the most typical protection equipment used in providing isolation, short-circuit and overload protection to a circuit or equipment. The 140-CMN-9000 is primarily designed for panel or DIN rail mounting and can be used to suit the protection degree requirement by each electrical circuit of a particular application. The 140-CMN-9000 has an adjustable trip setting via the device’s front panel. The trip setting range is 63 Amperes to 90 Amperes which can be modified by means of a precision screwdriver. The breaker’s ultimate short circuit breaking capacities are 50 Amperes at 230 / 240 VAC; 20 Amperes at 400 / 415 VAC; 10 Amperes at 500 VAC and 4 Amperes at 690 VAC while the rated short circuit capacities are 50 Amperes at 230 / 240 VAC; 8 Amperes at 400 / 415 VAC; 6Amperes at 500 VAC and 4 Amperes at 690 VAC. This breaker has a mechanical lifespan of 30000 operations, an electrical lifespan of 5000 operations, and a maximum switching frequency of 20 operations per hour. The overload protection class of this breaker is based on the IEC60947 standard with ambient temperature compensation of 20 to 60 Degree Celsius and an overload trip class of 10. This circuit breaker supports the installation of the main disconnection switch. Without the disconnect switch, the breaker is manually tripped using the mounted lever. It is also provided with a test button for checking the functionality of the breaker.
The Allen-Bradley 140-CMN-9000 Circuit Breaker is a Motor Protection Circuit Breaker with a rated operational current of 90 Amps. Some of the applications where this circuit breaker can be used are as a manual disconnect switch, as a magnetically activated short-circuit protection device, or as a thermally activated overload switch for motor branch circuits. It also has a fixed magnetic release trip current of approximately 1260 Amps. The thermal release trip current of the Allen-Bradley 140-CMN-9000 Motor Protection Circuit Breaker is user-adjustable by using a screw-type of wheel setting that can be seen on the front side the circuit breaker's case. For manual connection and disconnection, an external rotary operator is also placed on the front of the case.
With an estimated life expectancy of 30 years (approximately 30K switching operations for the mechanical parts or 5K switching operations for the electrical elements) given a favorable environment and regular maintenance, the Allen-Bradley 140-CMN-9000 Motor Protection Circuit Breaker is a reliable device for any type of industrial application. To extend the lifespan of the circuit breaker and get the most out of it, it is important to install it in a dry and dust-free environment, preferably inside a panel for additional environmental protection. Accessories such as auxiliary contacts, undervoltage trip, trip contact blocks, or shunt trip attachments are available for the Allen-Bradley 140-CMN-9000 Motor Protection Circuit Breaker. This circuit breaker is suitable for use in any single-phase application by connecting all the poles in series, in cases where there are no monopole circuit breakers available.
