Product Description
ABB · LOW VOLTAGE ACCESSORIES
1SDA073700R1
YU Undervoltage Release

A breaker accessory designed to provide an undervoltage release function for specified ABB SACE Tmax XT and SACE Emax 2 circuit-breaker frames.
220–240 V AC/DC YU Release ABB Accessory
01 / PRODUCT FUNCTION
What does the YU release do?
The 1SDA073700R1 is an undervoltage release accessory. It is intended for the specified breaker families and operates with a 220–240 V AC/DC control supply. Its role is tied to the breaker’s release mechanism, rather than serving as a standalone circuit breaker or protection relay.

The complete breaker frame designation and release arrangement should be checked before fitting. Similar-looking releases may have different voltage ratings or mechanical interfaces.
04 / SELECTION NOTES
Three checks that prevent a mismatch
A
Confirm the exact breaker frame
Check whether the installed breaker is within the stated E1.2–E6.2 or XT7 / XT7M range. Do not select the release by cabinet appearance alone.
B
Match the control supply
Verify that the control circuit is designed for 220–240 V AC/DC. A different voltage variant should not be treated as an equivalent replacement.
C
Check the release mounting and wiring
Before replacement, record the installed release position and control wiring. After fitting, have qualified personnel verify the breaker’s release response and operating sequence.
05 / BUYER QUESTIONS
FAQ · ABB 1SDA073700R1
1. Can ABB 1SDA073700R1 be used on every Emax 2 or Tmax XT breaker?
No. Its stated range is E1.2–E6.2 and XT7 / XT7M. Confirm the exact breaker frame and accessory arrangement rather than assuming that all Emax 2 or Tmax XT models share the same release interface.
2. What should be checked when replacing ABB 1SDA073700R1 with an existing release?
Compare the full part number, 220–240 V AC/DC rating, breaker frame, mounting location and terminal arrangement. A matching voltage alone does not prove mechanical or functional compatibility.
3. Does ABB 1SDA073700R1 provide overcurrent protection?
No. It is a YU undervoltage release accessory, not an overcurrent trip unit. The breaker’s protection functions are determined by its installed trip unit and overall configuration.
4. Is the 220–240 V rating of ABB 1SDA073700R1 valid for both AC and DC?
The product designation specifies 220–240 V AC/DC. Confirm the actual control-circuit supply and its characteristics against the breaker configuration before installation.
5. What commissioning checks matter after fitting ABB 1SDA073700R1?
A qualified technician should verify the release’s mechanical seating, control wiring, supply rating and the breaker’s expected response to the undervoltage condition before returning the equipment to service.
