Siemens 3RT6916-1CF00 Surge Suppressor 400-600V AC, RC Coupling for Motor Contactors S00 Original Brand New

Overview

The Siemens 3RT6916-1CF00 Surge Suppressor is an essential accessory for protecting sensitive control circuitry in industrial applications. As part of the reliable SIRIUS modular system, this RC element is specifically matched to handle the high-voltage requirements of 400 V to 600 V AC control coils on Size S00 devices, including motor contactors and contactor relays. Its plug-on design ensures fast, tool-free installation and optimal performance within the system.

Key Benefit

• Extended Contactor Lifespan: Protects the delicate contactor coil from high-energy “back EMF” voltage spikes generated when the coil is de-energized.

• Enhanced System Reliability: Prevents nuisance tripping and damage to surrounding electronic components (PLCs, VFDs) caused by electromagnetic interference (EMI).

• Optimized Performance: The RC coupling (Resistor-Capacitor) circuitry provides a balanced level of suppression with minimal impact on contactor dropout time compared to other suppression types.

• Fast, Tool-Free Installation: Designed as a simple clip-on accessory for SIRIUS Size S00 contactors, simplifying maintenance and assembly.

• Wide Voltage Compatibility: Engineered for a broad 400V to 600V AC range, making it versatile for various global industrial power standards.
