The 140M-I8P-B70S-CX circuit breaker is an adjustable magnetic circuit breaker manufactured by Allen-Bradley. It operates at 60 Hertz frequency and it comes with 1 normally open and 1 normally closed auxiliary contact. The breaker has an I Frame and it is conformally coated. The conformal coating helps the breaker to withstand harsh environmental conditions. The current rating of the breaker is 7 Amps and the input voltage rating is 480 Volts AC. The 140M-I8P-B70S-CX circuit breaker is a three-phase device with support for three poles. The circuit breaker actively monitors the system circuitry. It shuts down the circuit when the breaker detects overload current in the power supply. The breaker comes with both line and load side terminals. The breaker is also equipped with a button with a push-to-trip mechanism. It is a manual means for tripping the circuit breaker. The button has a plunger that rotates the trip bar, causing the motor circuit protector to trip. The breaker can be operated between -25 and 60 degrees Celsius and it can be stored at a temperature between -40 and 80 degrees Celsius when it is not in use.
The Allen-Bradley140M-I8P-B70S-CX circuit breaker comes with a rotary actuator and a visible trip indicator. It has a high switching capacity. The breaker provides Class 10 overload protection and short circuit protection for individual motor loads. The circuit breaker is equipped with trip/auxiliary contacts which save panel space. A trip testing button is present in the circuit breaker to check the functioning of the breaker. The 140M-I8P-B70S-CX circuit breaker is a molded case circuit breaker that provides overcurrent protection for conductors and equipment. The breaker meets the CE, CCC, CSA, and ATEX standards.
The 140M-I8P-B70S-CX circuit breaker is a three-phase circuit breaker. It also comes with three poles.
