Technical Specifications

Warranty & After-Sales

• Factory new units: 12 months warranty
• Refurbished units: 3-6 months warranty
• Bench test: Visual inspection → coil continuity/resistance measurement → 24V AC/DC energization test → trip actuation verification → mechanical fit check for XT7/XT7M and E1.2-E6.2 breaker frames → IEC compliance verification
• Technical support:
  • Breaker compatibility verification​ — confirming 1SDA073668R1 fits your specific ABB Tmax XT (XT7/XT7M) or Emax 2 (E1.2/E2.2/E4.2/E6.2) breaker frame
  • Control voltage confirmation​ — ensuring your control circuit is 24V AC or 24V DC
  • YO vs YC vs YU selection​ — helping distinguish:
    • YO​ (Shunt Opening) — remote trip → 1SDA073668R1 (24V DC) / 1SDA073674R1 (230V AC)
    • YC​ (Shunt Closing) — remote close → 1SDA073681R1 (24V DC) / 1SDA073687R1 (230V AC)
    • YU​ (Shunt Undervoltage) — undervoltage trip → 1SDA073694R1 (24V DC) / 1SDA073700R1 (220-240V AC) / 1SDA073703R1 (380-400V AC)
  • Primary vs secondary YO​ — the 1SDA073668R1 can be configured as first or second shunt opening release
  • Installation guidance​ — snap-in installation into breaker accessory compartment; wiring per ABB instruction manual “Opening coil YO/YO2 – E1.2 – XT7 – XT7M”
  • Complete breaker + accessory kit​ — supplying both the ABB breaker and the 1SDA073668R1 YO as a matched set
• Optional accessories: Other ABB Tmax XT / Emax 2 accessories (YO/YU/YC releases in different voltages, auxiliary contacts, motor operators), complete ABB circuit breaker units

⚠️ IMPORTANT — Read Before Ordering:

1. The 1SDA073668R1 is a SHUNT OPENING RELEASE (YO) / TRIP COIL, NOT a circuit breaker​ — you need a compatible ABB Tmax XT (XT7/XT7M) or Emax 2 (E1.2/E2.2/E4.2/E6.2) breaker frame for this device to function
2. Control voltage: 24V AC/DC​ — ensure your control circuit matches this range; for 230V AC version, use 1SDA073674R1
3. YO = Shunt Opening (trip) ONLY​ — it opens the breaker on command; it does NOT close the breaker (that’s YC) and does NOT respond to voltage drop (that’s YU — Undervoltage release)
4. Compatible ONLY with:
   • ABB SACE Tmax XT: XT7, XT7M
   • ABB SACE Emax 2: E1.2, E2.2, E4.2, E6.2
   • Not compatible with Tmax T1-T6, T8, or Emax 1 breaker frames
5. Snap-in installation​ — installs directly into the breaker’s accessory compartment; wiring follows ABB “Opening coil YO/YO2” instruction manual
6. Can be fitted as primary OR secondary trip coil​ — for applications requiring dual remote trip sources
7. Send us your ABB breaker model number — we’ll confirm the exact YO variant and provide a complete solution
