Product description

The Siemens 3RB2383-4AC1 is a bistable evaluation unit designed for full motor protection, covering Sizes S00 to S12. It offers adjustable tripping classes from 5 to 30 and is intended for stand-alone installation. This unit utilizes spring-type terminals for auxiliary circuits and supports manual and automatic reset functions. It interfaces with motor feeders, not having direct main circuit connections.

This evaluation unit is suited for applications requiring a bistable relay logic in motor protection systems, common in industrial control panels and machinery automation where specific relay states are advantageous. Its flexibility spans a wide range of motor sizes.

Frequently asked questions

What is the difference between the 3RB2283-4AA1 and 3RB2383-4AC1 evaluation units?

The primary difference is that the 3RB2283-4AA1 is a monostable evaluation unit, while the 3RB2383-4AC1 is a bistable unit. Bistable units maintain their state without continuous power, which can be advantageous in certain control logic scenarios.
