140M-I8P-D15-M

The 140M-I8P-D15-M Motor Protection Circuit Breaker is high braking, compact, and UL and CSA listed motor protection circuit breaker that is manufactured by Allen-Bradley/Rockwell Automation. It comes with 3 poles, a Size I frame, and 205 Amps of frame current. The circuit breaker has an adjustable magnetic trip for protection against electrical faults. The rated operational voltage of the circuit breaker is 600 Volts AC and the maximum current rating is 150 Amps. Its approximate weight is 4.5 pounds. This motor protection circuit breaker provides overload protection, as well as current limiting and short-circuit protection for individual motor loads. The 140M-I8P-D15-M Motor Protection Circuit Breaker is compatible with both AC and DC voltages.

The 140M-I8P-D15-M Motor Protection Circuit Breaker is useful in industrial applications such as heat pumps and cooling towers to prevent damages from power surges. The system of the circuit breaker interrupts immediately when a current or voltage level matches the circuit breaker's breaking capacity. These devices are traditionally used in two-component starter applications, and they are usually used with a contactor to control a motor load. Some of the functions of the 140M-I8P-D15-M motor protection circuit breaker include motor control, overload protection, short circuit protection, device protection, and disconnection functions. Any value above the maximum current rating of the circuit breaker will allow the breaker to trip. In low over current levels, the thermal protection features trips after a few minutes while line faults and peaks in currents cause an instant trip. This circuit breaker eliminates the need for other circuit breakers or individual motor circuit fuses while also reducing the panel size requirements and making the installation easy. Make sure that the circuit breaker is suitable for its intended application by comparing its nameplate data with the system requirements and existing system ratings.
