Overload Relay

Product Details:

Mitsubishi Overload Relay is a protection device used to safeguard motors from damage due to prolonged overload or overcurrent conditions. These overload relays are an essential part of motor control circuits and are used in conjunction with Mitsubishi contactors and PLC systems. The Mitsubishi overload relay monitors the current flowing through a motor and trips when the current exceeds the motor's rated capacity for an extended period, thus preventing overheating and potential damage to the motor.

Allen-Bradley Overload Relay is a protective device used in motor control circuits to safeguard motors from damage caused by overload or overcurrent conditions. These relays are designed to monitor the current flowing to a motor and will trip the circuit if the current exceeds a safe level for an extended period, preventing the motor from overheating and getting damaged.

Delta Overload Relays are protective devices used to safeguard electrical motors from overheating caused by overload conditions. These relays are part of Delta's comprehensive range of industrial automation products and are commonly used in motor control systems. The overload relay works by monitoring the current flowing to the motor and detecting conditions where the current exceeds safe operational limits for extended periods.

An Omron Overload Relay is a protective device used in electrical circuits to prevent motors and equipment from damage due to overload conditions. Omron, a well-known brand in automation and control technology, manufactures high-quality overload relays designed for various industrial applications. These relays are often used with electric motors to ensure that they do not operate beyond their rated capacity, helping to prevent overheating and potential failure.

Key Features of Omron Overload Relays:

1. Overload Protection: The primary function is to protect electric motors by monitoring the current passing through the circuit. If the current exceeds the motor's safe operating limits for an extended period, the relay will trip and disconnect the power, preventing damage to the motor.

2. Adjustable Settings: Omron overload relays often feature adjustable trip settings. This allows users to set the relay to trip at specific current levels, tailored to the motor's rated load and characteristics.

3. Thermal Overload Protection: Many Omron models use thermal protection, simulating the heating of the motor. The relay will trip once the motor is exposed to excessive heat caused by an overload, preventing thermal damage.

4. Motor Type Compatibility: Omron overload relays are designed to be compatible with different types of motors, such as standard induction motors, and may include settings to suit specific types like single-phase or three-phase motors.

5. Phase Loss Protection: Some models are equipped with phase-loss protection, which ensures the relay will disconnect if one of the phases in a three-phase system fails, thereby preventing the motor from running in an unsafe condition.

6. Ease of Use: Omron's overload relays often have user-friendly interfaces for easy calibration and monitoring, with clear indicators for status and alarms.

7. Resetting Mechanism: After an overload trip, many models include a manual or automatic reset feature, which allows for quick restoration of operation after the cause of the overload is addressed.
