Lawson ARC Series Fuse Links – Arcing Pattern Fuses at Casadaa Distribution

Rapid-acting, arc-resistant fuse-links designed for industrial control circuits and life-safety systems

At Casadaa Distribution, we stock the full range of Lawson ARC Series, also known as Artic Pattern HRC fuses, engineered to deliver fast-disconnect performance and improved arc control. These fuses are especially suited for emergency lighting inverters, selective coordination systems, and applications demanding extremely fast response and arc containment.

Manufactured by Lawson Fuses Ltd., part of the Lucy Group, the ARC Series includes fuse types such as A5‑*, MO‑*, OP‑*, all conforming to IEC 60269 and BS‑88 standards.

🔧 Key Features & Technical Data – Lawson ARC Series

• Voltage Ratings: typically 415 V AC (industrial control systems)

• Current Range: 2 A – 32 A (common OP and MO variants)

• Response Time: Ultra-rapid, designed for semiconductor and inverter output protection

• Arcing Pattern: Specialized body shape to withstand and direct arcs safely

• Fuse Body: Ceramic with bolted tags or flat tag terminations

• Typical Standards: BS 88, IEC 60269; often specified in life-safety system wiring

🧾 Popular ARC Series Part Numbers

Casadaa Distribution offers the key Lawson ARC part ranges:

• A5 Series: compact ceramic fuses with bolted tag connectors (e.g. A5‑4, A5‑10)

• MO Series: end-cap connection style for compact PCB studs (e.g. MO‑6, MO‑16, MO‑32)

• OP Series: flat‑tag connection with arcing pattern body (e.g. OP‑2, OP‑10, OP‑16, OP‑20, OP‑32)

All types available in gG (general purpose) characteristics. Typical current ratings span from 2 A to 32 A. These fuses are purpose-built to minimize arc energy and provide fast disconnection, especially critical in emergency circuits.

⚙️ Ideal Applications

• Emergency lighting inverter outputs

• Life‑safety circuit selective coordination (e.g. exit signs, fire alarm backup)

• Control systems requiring low I²t and fast tripping

• Small DC/AC drives & servo circuits

• Semiconductor protection where arc suppression is required

As noted by electricians on industry forums, ARC Series fuses are widely used for "emergency lighting inverters" where arc‑flash concerns demand ultra-fast, selective fuse protection".
