Overview
The Siemens 3RT2946-4EA4 is a high-quality accessory designed for the SIRIUS modular system, specifically functioning as a terminal cover for 4-pole box terminals on Size S3 contactors and associated overload relays. This essential component ensures touch-safe protection for electrical connections, enhancing safety and compliance within motor control and protection applications.
It is part of the extensive and efficient SIRIUS modular system, designed for seamless integration with Siemens 3RT2 power contactors (Size S3) and compatible overload relays (e.g., SIRIUS 3RU2 overload relays and 3RV2 circuit breakers). Manufactured in Germany, this product guarantees the reliability and precision expected from Siemens industrial control gear.
Benefit
- Enhanced Safety & Compliance: Provides crucial ingress protection (touch-safe cover) for energized terminals, preventing accidental contact and helping meet stringent electrical safety standards.
- System Integrity: Protects terminals from dust, debris, and foreign objects, ensuring the longevity and reliable operation of the contactor or overload relay.
- Perfect Fit: Specifically engineered for the dimensions and design of the SIRIUS Size S3 devices, guaranteeing quick and secure installation without modification.
- Durable & Reliable: Built with high-quality materials to withstand demanding industrial environments.
Function / Application
The 3RT2946-4EA4 terminal cover is an essential safety accessory used to cover the main circuit box terminals (power connections) on the following Size S3 devices:
- Siemens SIRIUS 3RT2 Power Contactors (Size S3)
- Siemens SIRIUS Overload Relays and Motor Circuit Breakers (when mounted with the S3 contactor)
Its primary function is to provide a protective barrier after wiring is complete, isolating the energized terminals to prevent electric shock or short circuits. This cover is vital for applications in motor control centers, load feeders, and industrial automation where safety and touch protection are mandated.
