JB/T 8978-2006 (English Version) PDF

Scope: This standard specifies the general basic rules and requirements for JZ20 series contactor relays (hereinafter referred to as relays), including terminology, characteristics, normal operating and installation conditions, structural and performance requirements, verification of characteristics and performance, etc. This standard applies to JZ20 series contactor relays. It is used in circuits with AC 50Hz (60Hz), rated working voltage 660V and below, and DC rated working voltage 220V and below. It can be used as remote control and automatic control components in the control circuit; it can be used as a contactor in the main circuit and can be used with Appropriate thermal relays or electronic protection devices form electromagnetic or mechatronic motor starters; among them, relays with smaller control power (0.5W) can be used as interface relays controlled by computers (or PCs).
