The EPCOS (TDK) R029D is a surge arrester designed to protect sensitive electronic equipment from voltage surges and transient overvoltages. These surges can originate from various sources, including lightning strikes, power grid switching, and electrostatic discharge (ESD). The R029D is a gas-filled surge arrester, which provides a robust and reliable solution for overvoltage protection.

• Low capacitance
• Fast response time
• RoHS compliant
• Compact size

Benefits

• Protects sensitive equipment from damage caused by voltage surges
• Improves the reliability and lifespan of electronic equipment
• Reduces downtime and repair costs
• Complies with industry standards for surge protection
• Easy to install

Additional Details

Gas-filled surge arresters, like the R029D, operate by conducting surge current to ground when the voltage exceeds a specific threshold, known as the spark-over voltage. This diverts the surge away from the protected equipment. After the surge has subsided, the arrester returns to its non-conducting state.

The specific technical specifications of the R029D, such as the spark-over voltage, surge current capability, and capacitance, can vary depending on the exact model. Refer to the EPCOS (TDK) datasheet for the precise specifications. The datasheet typically includes information on the arrester's dimensions, operating temperature range, and compliance with relevant safety standards.

Proper selection and installation of surge arresters are crucial for effective surge protection. Consider the expected surge environment, the sensitivity of the protected equipment, and the coordination with other protection devices when choosing a surge arrester. Consult with a qualified electrical engineer or surge protection specialist for assistance in designing a surge protection system.
