• Protection of Connections: Shields exposed box terminals from dust, foreign objects, and mechanical damage, prolonging the lifespan and reliability of the connected components.
• System Compatibility: Specifically engineered to fit the dimensions and terminal layout of Size S3 SIRIUS components (contactors, circuit breakers, overload relays) and the 3RW404 soft starter, guaranteeing a perfect fit and easy installation.
• Genuine Quality: As a Siemens original part, it ensures the highest quality, durability, and compatibility with your existing Siemens controlgear setup.

Function & Application

The 3RT2946-4EA2 cover snaps securely over the main current box terminals of compatible devices. Its primary function is to provide insulation and safeguard against touch hazards. It is a mandatory accessory for achieving a specified degree of protection against contact with the terminals, as required by many industrial regulations.

Typical Applications Include:

• Covering line and load terminals on SIRIUS Size S3 Contactors (e.g., 3RT2 contactors).
• Securing connections on Size S3 Motor Circuit Breakers and Overload Relays.
• Protecting the main terminals of the SIRIUS 3RW404 Soft Starter.

Installation

The terminal cover is designed for quick and tool-free installation. It typically clips directly onto the frame or housing of the respective Size S3 device or 3RW404 soft starter, providing a secure, insulating barrier over the box terminals. Always refer to the specific device’s manual (Contactor, Circuit Breaker, or Soft Starter) for exact installation instructions.
