Why Choose the ABB 1SCA022131R8690 OZXK1 Auxiliary Contact?
The ABB 1SCA022131R8690, order code OZXK1, is an industrial auxiliary contact with 1 normally open (1NO) and 1 normally closed (1NC) contact designed for use with compatible ABB switch-disconnectors. As part of the ABB 311020-OT/OETL Accessories product group, it provides reliable auxiliary switching for signalling, indication, interlocking and control functions in low-voltage electrical installations.
The OZXK1 is designed to provide additional control contacts that operate in conjunction with the associated switch mechanism. Its 1NO + 1NC contact configuration gives control-system designers both normally open and normally closed switching functions from a single accessory, making it suitable for status indication, electrical interlocking and auxiliary control circuits.
Designed for demanding switchgear applications, the OZXK1 has a 690 V rated insulation voltage and a 10 A conventional free-air thermal current. ABB documentation specifies OZXK auxiliary contacts as early-break contacts, with the normally open auxiliary contact opening before the associated main contacts, supporting dependable control and indication functions in industrial switchgear.

Reliable Auxiliary Switching for Industrial Switchgear
Auxiliary contacts provide electrical status and control signals independently of the main power contacts of a switch. The ABB OZXK1 adds one normally open and one normally closed contact, allowing connected control equipment to monitor or respond to operation of the associated switch-disconnector.
The OZXK1 is particularly useful in industrial switchgear where switch position needs to be communicated to control circuits, indicator devices, interlocking systems or automation equipment. Its early-break operating characteristic allows the normally open auxiliary contact to open before the associated main contacts, providing predictable auxiliary switching during switch operation.
Typical Applications
- ABB switch-disconnector auxiliary circuits.
- Electrical switchboards and distribution panels.
- Switch position and status indication.
- Electrical interlocking circuits.
- Industrial control and automation systems.
- Remote signalling and monitoring circuits.
- Machine and process control panels.
