Why Choose the ABB RC5-2/440 Surge Suppressor?
The ABB 1SBN050200R1003, type RC5-2/440, is a compact RC surge suppressor designed to protect conventional AC-operated contactor coils from damaging overvoltages and electrical interference. It reduces voltage peaks generated when inductive loads are switched off, helping improve switching reliability and protect sensitive components in industrial control systems.
The RC5-2/440 is designed for ABB contactors and contactor relays with a rated control circuit voltage of 250–440 V AC at 50/60 Hz. Its RC suppression technology reduces overvoltage peaks and limits high-frequency transient disturbances caused by switching inductive loads.
With a compact clip-on mounting design, the RC5-2/440 can be installed directly onto compatible ABB contactors or contactor relay bases without changing the overall device dimensions. This provides a simple solution for improving coil protection and reducing electrical noise in automation panels.
