UFC721BE101 3BHE021889R0101 – ABB Overload Relay - Description:
The UFC721BE101 3BHE021889R0101 is an overload relay from ABB, designed to protect electrical motors and circuits from damage caused by overloads or excessive current. Overload relays monitor the current flow in a circuit and trip (interrupt the circuit) usually caused by motor overload conditions. This allows the motor to be safely shut down, preventing damage and potential fire hazards. - Product Parameters:
Key parameters of the UFC721BE101 3BHE021889R0101 overload relay include: - Rated Current: The maximum continuous current the relay can handle without tripping.
Tripping Current: The current level at which the relay will trip and interrupt the circuit.
Tripping Time: The time it takes for the relay to trip once the current exceeds the tripping level.
Thermal Memory: The ability of the relay to remember the heat generated by the current and trip accordingly, even if the current drops below the tripping level temporarily.
Mechanical Life: The estimated number of trips the relay can endure before wearing out.
Electrical Life: The estimated number of electrical operations (cycles of energizing and de-energizing) the relay can handle before failing.
Compliance Standards: The safety and performance standards the relay meets, such as IEC or UL. - Product Specification:
The specification of the UFC721BE101 3BHE021889R0101 overload relay provides detailed technical information about its design, capabilities, and dimensions. The specification typically covers: - Dimensions: Length, width, height, and any critical dimensions of the relay.
Weight: The mass of the relay.
Mounting Instructions: Guidelines for properly mounting the relay on a panel or chassis.
Electrical Characteristics: Detailed electrical parameters such as rated current, tripping current, and voltage ratings.
Environmental Conditions: The temperature, humidity, and other environmental factors within which the relay can operate safely.
Compliance and Certifications: Information about any safety or performance certifications the relay holds, such as CE or UL. - For accurate and detailed information about the UFC721BE101 3BHE021889R0101 overload relay, it is recommended to consult the product’s manual, datasheet, or contact ABB directly for additional specifications and technical support.
