Why this FAQ?
Engineers and buyers need one-page, spec-accurate answers to evaluate XT1B 160 TMD 63 A for panel design and maintenance. This set highlights ratings, installation cues, and ordering through an authorized partner.
What is the ABB XT1B 160 TMD 63 A 4P F F MCCB?
It is a SACE Tmax XT moulded case circuit breaker, 4-pole, fixed version with front terminals, thermomagnetic TMD trip. Frame Iu is 160 A; this code has In 63 A with adjustable Ir 44.1–63 A and instantaneous Ii fixed at 630 A. Short-circuit performance level: B. Product ID: 1SDA066816R1; EAN: 8015644007232.
What breaking capacities does it provide (Icu/Ics)?
AC Icu/Ics: 220–240 V: 25/25 kA; 380–415 V: 18/18 kA; 440 V: 15/11.25 kA; 500 V: 8/8 kA; 525 V: 6/6 kA; 690 V: 3/3 kA. DC: 250 V (2 poles in series): 18/18 kA. Selectivity/coordination depend on the upstream/downstream devices—refer to ABB tables for verification.
Rated operational voltage: 690 V AC, 500 V DC; frequency 50/60 Hz; current type: AC/DC. Rated insulation voltage Ui: 800 V; impulse withstand Uimp: 8 kV. Rated uninterrupted current (frame) Iu: 160 A. Size: 101.6 × 130 × 70 mm (W×H×D); weight: 1.4 kg. Front bolt terminals (M6), tightening torque 6 N·m; recommended driver: M6. Main circuit busbar connecting capacity: 45.5…80 mm². Power loss at rated conditions: ~4.3 W per pole.What are the voltage and insulation ratings?
What are the dimensions, weight, and terminals?
What is the trip unit and adjustment range?
Thermomagnetic TMD release (TM). Adjustable thermal Ir: 44.1–63 A; instantaneous short-circuit setting Ii: 630 A (fixed). For detailed I²t characteristics and time-current curves, refer datasheet / contact Shansen for confirmation.
How durable is it and how fast does it open?
Electrical durability: 8,000 operations at up to 120 cycles/hour. Mechanical durability: 25,000 operations at up to 240 cycles/hour. With shunt opening release (SOR) or undervoltage release (UVR), typical opening time is ~30 ms.
Is it suitable for AC/DC distribution and motor feeders?
Yes—rated for AC up to 690 V and DC up to 500 V (see DC Icu/Ics note for 2 poles in series at 250 V). Suitable for power distribution feeders and small motor feeders where TMD curves meet coordination. For motor protection classes/coordination (Type 1/2) and selectivity, refer datasheet / ABB coordination tables.
Which standards and compliance does it meet?
Complies with IEC 60947-2. For additional approvals/markings (UL/CE/RoHS) specific to this code, refer datasheet / contact Shansen for confirmation. Use appropriate IP enclosure and clearances per panel design and standards.
What installation notes should I follow?
Use 6 N·m torque on M6 main terminals and size conductors/busbars within the stated capacity. Verify ambient temperature, derating, clearances/creepage, and tightening after thermal cycling—refer datasheet. Ensure accessories (SOR/UVR/aux contacts) are correctly coded and interlocked as per ABB instructions.
