Siemens B33000S01 - 30 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens B33000S01 — a 30A, 240V, 3-pole bolt-on molded case circuit breaker engineered for dependable branch circuit protection in panelboards and load centers. Built for toughness and precise protection, it’s the right choice when reliability matters in residential, commercial, and light industrial settings.

Why this breaker stands out

• delivers a rigid, vibration-resistant bus connection. This reduces movement that can lead to loose contacts over time, helping maintain consistent protection and minimizing nuisance trips in environments with equipment vibration.
• provides stable, repeatable response to overloads and short circuits. The combination of thermal (overload) and magnetic (short-circuit) protection helps guard downstream equipment while staying sensitive enough to trip when it matters.
• ensures straightforward replacement or upgrade in Siemens-aligned panelboards and load centers without additional adapters or modifications.
• is suitable for a range of applications—from home electrical panels to light commercial distribution boards and small industrial setups where reliable protection is essential.
