Why Choose the ABB YU E1.2..E6.2 60 Vac/dc Undervoltage Release?
The ABB YU E1.2..E6.2 60 Vac/dc, order code 1SDA073697R1, is a 60 V AC/DC undervoltage release designed for compatible ABB low-voltage circuit breakers. Part of the electrical accessory range for ABB SACE Emax 2, it provides fail-safe circuit-breaker control by allowing the breaker to remain closed only while the release receives an adequate control supply.
The YU undervoltage release continuously monitors its control voltage and acts on the circuit-breaker mechanism if the voltage falls below the required operating level or is removed. This functionality is particularly useful in electrical protection and control schemes where automatic breaker opening is required following loss or significant reduction of the control supply.
Rated for a 60 V AC/DC control supply, the 1SDA073697R1 can operate from both AC and DC control circuits. It is designed for ABB SACE Emax 2 E1.2, E2.2, E4.2 and E6.2 circuit breakers and is also compatible with applicable SACE Tmax XT7 and XT7M devices, providing a versatile solution for industrial and infrastructure switchgear.

Reliable Undervoltage Circuit Breaker Control
An undervoltage release is used where a circuit breaker must respond automatically to loss or excessive reduction of its control voltage. The YU release interacts with the breaker operating mechanism so that the circuit breaker cannot remain closed when the control supply is insufficient, providing a fail-safe function for electrical distribution and machinery control systems.
The ABB 1SDA073697R1 combines this undervoltage functionality with a 60 V AC/DC control rating, making it suitable for a variety of control architectures. Its compatibility with multiple Emax 2 frame sizes allows the same accessory family to be applied across a broad range of ABB low-voltage switchgear installations.
Typical Applications
- Undervoltage protection for ABB SACE Emax 2 air circuit breakers.
- Low-voltage power distribution switchboards.
- Industrial electrical control and automation systems.
- Fail-safe circuit-breaker control schemes.
- Commercial and infrastructure power distribution installations.
- Compatible ABB SACE Tmax XT7 and XT7M circuit-breaker systems.
