Why Choose the ABB 1SDA054920R1 AUP-I Position Contact?
The ABB 1SDA054920R1 is an AUP-I position contact designed for compatible ABB SACE Tmax T4, T5 and T6 moulded case circuit breakers. As part of the ABB Tmax T4–T6 accessory range, it provides electrical indication that a removable circuit breaker is in the inserted position.
Position contacts are used in withdrawable and plug-in circuit breaker installations to communicate the physical connection state of the breaker to external control, indication and automation equipment. The AUP-I version is specifically associated with the inserted / connected position, helping supervisory systems confirm that the breaker is correctly engaged with its fixed part.
The 1SDA054920R1 is designed for a 24 V DC signalling circuit and for use with compatible Tmax T4, T5 and T6 installations. It provides a dedicated ABB solution for remote position feedback in switchboards, industrial distribution panels and automated power systems.

Reliable Circuit Breaker Position Monitoring
Circuit breaker position contacts provide electrical feedback about the mechanical connection state of removable breakers. This information can be transmitted to indication lamps, PLC inputs, supervisory control systems and electrical interlocking circuits, allowing the switchboard control system to determine whether the breaker is correctly positioned.
The ABB 1SDA054920R1 provides dedicated inserted-position feedback for compatible Tmax T4, T5 and T6 installations using a 24 V DC signalling circuit. This helps improve visibility of breaker status and supports coordinated automation and interlocking within industrial power distribution systems.
Typical Applications
- Inserted-position indication for ABB Tmax T4, T5 and T6 circuit breakers.
- Industrial switchboard position monitoring.
- PLC and automation system status inputs.
- Electrical interlocking systems.
- Remote breaker-position indication panels.
- Industrial and commercial power distribution assemblies.
