Product Description:
The MCGE31-0 is a B & R Automation contactor module for industrial automation. It is designed with three poles for switching and controlling electrical power in various automation systems. This module plays a crucial role in managing motor loads, actuators, and other high-current devices within industrial control panels. Suitable for use in manufacturing, material handling, and processing plants, this module supports reliable operation in systems where frequent electrical switching is required. Its robust design makes it ideal for integration into automated systems.
The MCGE31-0 is equipped with a rated operational voltage of 690V AC, which allows it to manage and switch high-voltage electrical circuits in industrial environments with reliability and safety. This voltage rating makes the module suitable for applications involving large motors, heating elements, or power distribution units where elevated voltage levels are standard. The high voltage capability reduces the need for additional step-down transformers or intermediate switching devices, streamlining system design and improving efficiency. This unit features a rated operational current of 31 A, enabling it to handle moderate to high current loads.
The MCGE31-0 has a derating value of -3 A at 40°C, which indicates that when the ambient temperature reaches 40°C, the maximum operational current of the contactor must be reduced by 3 amps from its rated value. This adjustment ensures the component operates safely within its thermal limits, as higher ambient temperatures increase the risk of internal heat accumulation. This module is designed to offer an electrical life of 1,000,000 operations, meaning it can reliably make and break electrical circuits one million times under standard operating conditions. This extended electrical endurance, minimizes maintenance intervals and reduces the risk of unexpected downtime.
