1. Overview

The DZ-430 series intermediate relay is used for various protection and automatic control devices in AC/DC operations to increase the number and capacity of contacts. The DZ-431 type is used for DC circuits, while the DZ-432 type is used for AC circuits.
2. Structure

The principle of relay operation is electromagnetic.
The basic housing of this relay adopts JCK-11/3 housing components from the JCK-10 series housing assembly. There are protruding front and rear wiring.

3. Main technical data of DZ-430 series intermediate relay

The main technical data of DZ-430 series intermediate relays are shown in the table



Note: The combination form and quantity of contacts are represented by a 4-digit code, listed after the model number, sequentially indicating dynamic closing, dynamic breaking, conversion, and transition conversion. For example, DZ-431/4022 has 4 dynamic combinations, 0 dynamic breaks, 2 conversions, 2 transition conversions, and so on.
