OESAZX1 ABB 1 NO + 1 NC Auxiliary Contact

Why Choose the ABB OESAZX1 1 NO + 1 NC Auxiliary Contact?

The ABB OESAZX1, ABB product ID 1SCA022026R3300, is an auxiliary contact assembly with 1 normally open (NO) and 1 normally closed (NC) contact designed for use with compatible ABB switching equipment. As part of the ABB OS/OESA accessory range, it provides additional electrical contacts for signalling, indication, monitoring and control functions.

The OESAZX1 allows the operating state of compatible switching equipment to be incorporated into an external control circuit without using the main power contacts for signalling. Its complementary 1 NO + 1 NC configuration provides both normally open and normally closed contact functions, making it suitable for applications requiring two complementary status signals.

Designed as a genuine ABB accessory, the OESAZX1 provides a practical solution for adding auxiliary signalling to industrial switchboards, distribution panels and machinery. It can be used for applications such as switch-position indication, electrical interlocking, control-system feedback and remote status monitoring.

Reliable Auxiliary Signalling and Switch-Status Feedback

Auxiliary contacts provide electrical status signals associated with the operation of a switching device while remaining separate from the main power circuit. The ABB OESAZX1 provides both a normally open and normally closed contact, enabling complementary signals to be incorporated into indication lamps, relays, programmable controllers and other control equipment.

This 1 NO + 1 NC arrangement gives electrical designers flexibility when implementing switch-position feedback, permissive circuits and electrical interlocking. As a purpose-designed ABB OS/OESA accessory, the OESAZX1 is suitable for industrial installations where dependable auxiliary status information is required from compatible switching equipment.

Typical Applications

• Switch-position indication circuits.
• Industrial electrical switchboards.
• Low-voltage distribution panels.
• Electrical interlocking circuits.
• Motor control centres and machinery panels.
• PLC and automation system status feedback.
