RG1988-3

Overview

The Electrocube RG1988-3 is a single-phase RC network designed for arc suppression and transient voltage protection. It features a capacitance of 0.25 µF with a tolerance of ±20% and a resistance of 68 Ohms. The component is rated for 900V DC and 250V AC, with a power dissipation capacity of 0.5W. It utilizes stranded wire leads, specifically #18AWG MTW leads, to facilitate easy free-hanging mounting across coils and contacts in industrial applications.

Feature Summary

• Single-phase RC network configuration for effective arc suppression
• Compact design allowing for easy free-hanging installation
• Stranded wire leads for flexible mounting across electrical components

Applications

• Arc suppression across contactors and relays
• Transient voltage protection in motor control circuits
• Industrial power conversion and control systems

Procurement Notes

Verify the specific lead length and termination style required for your application, as variations such as RG1988-3-6 may exist with different lead lengths. Confirm that the 68 Ohm resistance and 0.25 µF capacitance values align with your circuit's transient suppression requirements. Ensure the 250V AC / 900V DC ratings exceed the maximum operating voltages of the protected equipment to guarantee reliable performance and safety compliance.

Selection Notes

Select this component when a single-phase RC snubber is needed for low-to-medium voltage AC or DC circuits. The 68 Ohm resistor value is suitable for limiting inrush current while damping oscillations. Consider the physical size and lead length for adequate clearance from other components. This series is appropriate for general industrial environments where compact, high-reliability arc suppression is required without complex mounting hardware.

Part Context

Electrocube manufactures a comprehensive range of RC networks, including single-phase and three-phase variants. The RG1988 series represents their standard line of leaky capacitors and RC networks, widely used in industrial automation. These components are engineered to extend the life of switching devices by suppressing arcing at the contacts. The brand emphasizes high reliability and compact form factors for integration into tight control panels.

Replacement Considerations

Direct substitutes include other Electrocube models within the RG1988 series with matching electrical parameters. Verify that any replacement maintains the same 0.25 µF capacitance and 68 Ohm resistance. Ensure the voltage rating meets or exceeds the original 250V AC / 900V DC specifications. Check lead type and length compatibility if space constraints are critical.
