lewsin — Thu, 22 May 2025 05:35:51 +0000

CJX20901 AC contactor is a small AC contactor with a rated working current of 9A, equipped with 1 set of normally closed auxiliary contacts and 0 set of normally open auxiliary contacts, mainly used for controlling the on/off of circuits.
The following is a detailed introduction about CJX20901 AC contactor:
1. Analysis of Model Meaning
The naming convention for CJX20901 is as follows:
C: Represents a contactor.
J: Representative Communication (AC).
X: Represents miniaturization (miniaturization design).
2: Design number.
09: The rated working current is 9A.
01: Refers to the configuration of auxiliary contacts, where “0” represents 0 sets of normally open auxiliary contacts, and “1” represents 1 set of normally closed auxiliary contacts.
2. Structure and Function
Main contacts: There are usually three sets of main contacts used to control the on/off of the main circuit, allowing for larger currents (such as 9A) to pass through.
Auxiliary contact:
Normally closed contact (NC): default closed, disconnected when the coil is energized.
Normally open contact (NO): default open, closed when the coil is energized.
The auxiliary contacts of CJX20901 are configured as one set of normally closed (non open).
Working principle: After the coil is energized, a magnetic field is generated, which attracts the armature and drives the contact to move. The main contact closes, and the auxiliary contact switches states according to the configuration.
3. Application scenarios
Suitable for circuits with AC frequency of 50Hz/60Hz and voltage up to 660V, commonly used in motor control, power distribution systems, etc.
Can be combined with other components (such as thermal relays) to expand functionality (such as electromagnetic starters).
4. Model Expansion and Variants
In similar models, the last digit may be different, for example:
CJX20910:1 set of normally open and 0 set of normally closed auxiliary contacts.
CJX20922:2 sets of normally open and 2 sets of normally closed auxiliary contacts.
5. Testing and maintenance
A multimeter can be used to test the on/off status of the contacts and determine the quality of the contactor.
Pay attention to the numbering pattern of auxiliary contacts: a single digit of 1 or 2 indicates normally closed, while a single digit of 3 or 4 indicates normally open.
Summary: CJX20901 is a small AC contactor with a compact design, suitable for small and medium current control scenarios. Its model code directly reflects key parameters, making it easy to select and use
