Whether you’re an electrical contractor, facility manager, or DIY enthusiast, the ABB SB202M‑C63 2‑pole, 63 A Type C Miniature Circuit Breaker (MCB) delivers reliable overload and short‑circuit protection for residential, commercial, and industrial installations. Below, we’ve gathered the most common questions about this compact power-saver and answered them in clear, easy–to–understand language.
1. What exactly is the ABB SB202M‑C63 MCB?
The SB202M‑C63 is part of ABB’s System pro M compact SB200M family of MCBs. It’s a two‑pole breaker rated at 63 amps with a Type C tripping characteristic. That means it handles normal overloads via a thermal trip and interrupts high‑fault currents instantly through an electromechanical trip. It complies with IS/IEC 60898‑1 standards, making it suitable for homes, offices, factories, and more.
2. What does “Type C” tripping characteristic mean?
Type C breakers are designed to trip when the current reaches 5 to 10 times their rated current. In plain English, the SB202M‑C63 will tolerate harmless inrush currents—like motor start‑ups—without nuisance trips, but will still react swiftly to genuine short‑circuits or dangerous overloads.
3. How does the SB202M‑C63 limit short‑circuit energy?
Thanks to its current‑limiting design and electromechanical trip, this MCB chops off high‑energy arcs in under a half‑cycle during severe faults. The result? Far less thermal and mechanical stress on your wiring and equipment, and a reduced fire hazard in critical applications.
