ABB RC5-2/50 Surge Suppressor – 1SBN050200R1000
- Product Name : Contactor
- Product Class : Surge Suppressors
- Terminal Type : Screw Terminals
The RC5-2/50 is an RC-type surge suppressor designed to minimize peak overvoltage and effectively limit or eliminate high pre-damping voltage frequencies. It is used with AC-operated conventional contactors within a rated control circuit voltage range of 24 to 50 V AC at 50/60Hz. Inductive circuit operation often generates overvoltages, especially when the contactor coil is opened. During closing, electromagnetic energy is stored in the coil and released upon opening, resulting in surges that can reach several kilovolts. These surges may cause electronic interference, insulation breakdown, or even damage to sensitive components. The RC5-2/50 provides significant advantages, including easy installation by clipping onto the top or side of the contactor or contactor relay base without altering the device’s overall dimensions. Additionally, it ensures rapid suppression of voltage surges, reducing steep fronts and high-frequency disturbances without causing operating delays.
