Product Positioning

3RT1966-4EA2 is a special protective cover for Siemens SIRIUS large contactors used with box terminals. Its main function is to shield the box terminal openings of S10 and S12 housing contactors, overload relay 3RB106, and soft starters 3RW407 and 3RW444. With a "finger-safe" design, it reduces the risk of operators accidentally touching live terminals with their fingers. It is a common safety accessory when installing on distribution panels.

Core Product Advantages and Features

Finger-proof safety design

A protective structure is designed for the opening of the box-type terminal to prevent fingers from accidentally touching the live terminals.

Multi-product sharing

In addition to the contactor itself, it can also be used with the 3RB106 overload relay and the 3RW407 and 3RW444 soft starters. Spare parts can be shared across different models.

Small size and easy to install

The dimensions are approximately 145×66×37.6 mm, and the weight is only about 0.08 pounds, so it does not affect the existing wiring space.

Compatible with S10/S12 chassis

The dimensions are specifically designed for SIRIUS large housing 3RT1_6/3RT1_7 series, and the snap-fit structure fits the shape of the original terminal block.
