Why Choose the ABB 1SDA073772R1 RTC Ekip 24V DC E1.2 Contact?
The ABB 1SDA073772R1 is an RTC Ekip 24 V DC ready-to-close signalling contact designed for ABB Emax 2 E1.2 air circuit breakers. Part of the ABB Emax 2 air circuit breaker accessory range, it provides a digital signalling contact that indicates when the circuit breaker is in the correct operating condition and ready to receive a closing command.
The RTC Ekip contact is particularly useful in automated power distribution systems where circuit breaker readiness must be monitored by an electronic control system. Its digital-signal design allows ready-to-close information to be integrated with Ekip-based control architectures, PLCs, switchboard automation equipment and supervisory systems.
Designed for the ABB Emax 2 E1.2 frame, the 1SDA073772R1 is the 24 V DC Ekip version of the RTC accessory and provides one change-over contact. It is also suitable for compatible ABB Tmax XT7 and XT7M circuit breakers, providing ready-to-close signalling across supported ABB low-voltage protection platforms.
Key Advantages
- Provides reliable ready-to-close circuit breaker status signalling.
- Ekip digital-signal version for integration with electronic control systems.
- 24 V DC configuration suitable for low-voltage automation applications.
- Designed for ABB Emax 2 E1.2 air circuit breakers.
- Provides one change-over contact for ready-to-close signalling.
- Also suitable for compatible ABB Tmax XT7 and XT7M circuit breakers.
Key Features
- ABB Emax 2 RTC Ekip ready-to-close contact.
- 24 V DC digital signalling version.
- Compatible with Emax 2 E1.2 air circuit breakers.
- One change-over contact.
- Signals when the circuit breaker is ready for a closing operation.

- ABB order code 1SDA073772R1.
Reliable Ekip Ready-to-Close Signalling
A ready-to-close contact enables an electrical control system to determine whether a circuit breaker is in the correct condition to perform a closing operation. This is particularly valuable in automated switchboards and remotely controlled power distribution systems where closing commands may be issued by an automation or supervisory system.
The ABB 1SDA073772R1 is specifically configured for digital signalling, with a minimum load of 1 mA at 5 V. This distinguishes the Ekip version from the standard RTC contact and makes it suitable for interfacing with electronic control equipment where low-level digital signals are used for circuit breaker monitoring and automation.
Typical Applications
- ABB Emax 2 E1.2 air circuit breaker installations.
- Ekip-based circuit breaker control and monitoring systems.
- Ready-to-close circuit breaker status indication.
- Industrial low-voltage switchboards.
- PLC and digital automation system inputs.
- Compatible ABB Tmax XT7 and XT7M circuit breaker applications.
