What type of component is this?

This component is an electronic time-delay device designed for an undervoltage release in an ABB SACE Tmax XT molded-case circuit breaker system.

What is the purpose of the electronic time delay?

The time-delay function helps prevent the undervoltage release from responding immediately to brief voltage dips. This can reduce unwanted breaker operation during short, temporary supply disturbances.

Which circuit breaker frame sizes are compatible with this accessory?

ABB 1SDA101981R1 is intended for SACE Tmax XT5 and XT6 circuit breaker frame sizes.

What is the rated operating voltage?

The device is rated for 110 to 125 V AC or 110 to 125 V DC.

Can this device be used with both AC and DC control supplies?

Yes. It is designed to operate within the specified 110 to 125 V range using either an AC or DC control supply.

Is this component a complete circuit breaker?

No. It is an electrical accessory for a compatible molded-case circuit breaker and is not a complete breaker.

What type of breaker accessory is it?

It is classified as a delay device for an undervoltage release, within the electrical accessories and auxiliary contacts product group.

What is an undervoltage release?

An undervoltage release is a circuit breaker accessory that responds when its control voltage falls below the required level. Depending on the breaker configuration, it can cause the breaker to open or prevent it from closing until adequate voltage is restored.

What should be checked before selecting this accessory?

Confirm the circuit breaker series and frame size, the undervoltage release configuration, and whether the control supply is within the 110 to 125 V AC/DC rating. The breaker documentation and electrical arrangement should also be reviewed for compatibility.

Does the device comply with recognized electrical standards?

The product documentation identifies IEC and UL standards and certifications for this accessory.

Where is this type of accessory commonly used?

This type of accessory is commonly integrated into industrial power distribution and control panels using compatible SACE Tmax XT5 or XT6 molded-case circuit breakers.

Can it be used with other SACE Tmax XT frame sizes?

The stated frame-size compatibility is XT5 and XT6. Use with another frame size should not be assumed without confirming the breaker and accessory specifications.
