SIBA 189140 T1.25A 1.25A 500VAC aR Fast‑Acting Fuse, 6.3×32 mm – Pack of 10

SIBA 189140 T1.25A 1.25A 500VAC aR Fast‑Acting Fuse (Pack of 10)

Overview
The SIBA 189140 T1.25A is a high‑performance, fast‑acting (aR) cylindrical fuse designed for supplemental over‑current protection in electronic and low‑voltage control circuits. Rated at 1.25 A and 500 VAC, the compact 6.3 mm × 32 mm body fits standard European‑style fuse holders and provides reliable fault clearing with a 10 kA breaking capacity. The 10‑piece bulk pack makes stocking and replacement convenient for production, maintenance, and inventory management.

Key Features

• Fast‑Acting (aR) Design – clears faults quickly while allowing harmless inrush currents.
• Rated 1.25 A at 500 VAC – suitable for low‑voltage AC control and signal circuits.
• High Interrupting Capacity – 10 kA AC, ensuring safety in circuits where the available short‑circuit current does not exceed this value.
• Compact 6.3 × 32 mm Body – fits common European‑style (E‑5) fuse clips, saving panel space.
• IEC 60269‑4 Compliant – meets international standards for fast‑acting fuses.
• RoHS‑Compliant – free of hazardous substances.
• Pack of 10 – convenient bulk packaging for multiple installations.
• Manufacturer: SIBA – a trusted German brand in circuit protection for decades.

Typical Applications

• Supplemental protection for control circuits, lighting, sensors, and low‑power motors.
• Protection of power‑supply rails, PLC inputs, and small‑scale automation equipment.
• Not intended for branch‑circuit protection; use where fault current is limited to ≤ 10 kA.
