A1B330 – 30 Amp Circuit Breaker

The A1B330 – 30 Amp Circuit Breaker is designed to deliver dependable, long-lasting protection for your electrical system, whether you’re outfitting a home, office, or light industrial setup. With its 3‑pole, bolt‑on build and thermal‑magnetic technology, this breaker gives you the assurance of precise response to overloads or short circuits — and keeps circuits running smoothly when you need them most. Its compact size and 30 A rating make it a versatile choice for upgrading or building electrical panels where safety and reliability count.

Key Features and Benefits

• Clear 30 Amp protection — Perfect for managing moderate electrical loads in residential, commercial, or light‑industrial environments.
• High A.I.C. rating — With 10k A.I.C. at 240 VAC, this breaker helps guard against high‑fault currents and reduces the risk of equipment damage from short circuits.
• Space‑efficient form factor — Measuring just 2.25″ W × 6.00″ L × 2.31″ D, the A1B330 fits neatly into panelboards with limited space, making it ideal for compact electrical enclosures.
• Thermal‑magnetic trip mechanism — Combines long-term overload protection (thermal) with instantaneous short‑circuit response (magnetic), giving double-layer safeguarding that responds fast and accurately.
• Consistent performance over time — Built for durability and reliable operation, so you can count on steady circuit protection day in, day out.
