OESAZX25 ABB Auxiliary Contact Set 8 N/O 8 N/C

Why Choose the ABB OESAZX25 Auxiliary Contact Set?

The ABB OESAZX25 is an auxiliary contact set with 8 normally open and 8 normally closed contacts designed as an accessory for compatible ABB OS/OESA switching equipment. Identified by ABB order code 1SCA022053R5910, it forms part of the ABB OS/OESA accessories range and provides extensive auxiliary switching capacity for control, indication and interlocking circuits.

With a total of 16 auxiliary contacts, comprising 8 N/O and 8 N/C contacts, the OESAZX25 allows the operating state of compatible switching equipment to be incorporated into multiple secondary circuits. This makes it useful where several status signals, control functions or electrical interlocks are required from the associated switching device.

The OESAZX25 is suited to industrial switchboards, power-distribution assemblies and control panels using compatible ABB OS/OESA equipment. As a purpose-designed ABB accessory, it provides a coordinated solution for expanding auxiliary-contact functionality within industrial switching systems.

Expanded Auxiliary Control for Industrial Switching

Auxiliary contacts provide secondary switching signals that correspond with the operating state of compatible primary switching equipment. These signals can be incorporated into control circuits for status indication, electrical interlocking, sequencing and other automation functions without serving as the main power-switching contacts.

The ABB OESAZX25 provides 8 normally open and 8 normally closed auxiliary contacts, allowing multiple circuits to respond to the state of the associated switching equipment. This extensive contact arrangement is particularly useful in switchgear and control systems requiring numerous independent feedback or interlocking paths.

Typical Applications

• Compatible ABB OS/OESA switching installations.
• Switch-position and operating-status indication.
• Electrical interlocking circuits.
• Industrial switchboards and distribution panels.
• Control sequencing and automation systems.
• OEM switchgear and panel-building applications.
