Product Description

Siemens 3RT2936-1CC00 Surge Suppressor RC Element for SIRIUS Contactors

The Siemens 3RT2936-1CC00 is a genuine SIRIUS surge suppressor RC element designed to protect contactor coils and associated control circuits from voltage spikes generated during switching operations. This accessory is specifically developed for Siemens SIRIUS 3RT2 contactors (Size S2) and helps improve system reliability by minimizing transient overvoltages and electromagnetic interference (EMI).

The RC suppressor is suitable for 48–127V AC (50/60 Hz) and 70–150V DC control circuits. When mounted directly across the contactor coil, it absorbs switching surges and suppresses voltage peaks that could otherwise damage sensitive devices such as PLCs, relays, timers, sensors, and electronic control equipment.

Designed for seamless integration with Siemens SIRIUS 3RT2 Size S2 contactors, the 3RT2936-1CC00 features a compact clip-on mounting design that allows quick installation without modifying the control circuit. Its compact dimensions help save valuable panel space while providing reliable surge suppression performance.

By reducing coil-generated switching transients, the suppressor helps prevent nuisance tripping, minimizes electrical noise, reduces contact wear, and improves overall control system stability. This makes it particularly valuable in motor control centers (MCCs), industrial automation systems, process plants, HVAC installations, water treatment facilities, and manufacturing operations.

Manufactured according to Siemens quality standards, the 3RT2936-1CC00 RC Element delivers dependable long-term performance and full compatibility with Siemens SIRIUS switching devices. It is commonly used as a preventive protection accessory in industrial control circuits where reliable contactor operation is essential.
