Siemens B35000S01 - 50 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens B35000S01 delivers reliable branch circuit overcurrent and short-circuit protection in a 3-pole bolt-on molded case design. With a 50A rating at 240V, it’s built to handle distribution tasks in panelboards and load centers across residential, commercial, and light industrial settings.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, minimizing movement and maintaining consistent electrical contact in environments with panel vibration or movement.
• Thermal-magnetic trip unit combines thermal overload protection with magnetic short-circuit protection for stable, repeatable performance across a range of load conditions and fault events.
• 3-pole, 50A, 240V configuration ensures coordinated protection across all three phases, preventing phase imbalance and delivering reliable protection for multi-wire circuits.
• OEM panel compatibility is designed to fit Siemens-load centers and panelboards, enabling straightforward replacement or upgrade in existing installations without adapters.
• Versatile applications suited for residential, commercial, and light industrial distributions, including feeders and branch circuits in service panels that demand dependable protection.

Why choose bolt-on for panel installations? The bolt-on design delivers a more rigid bus connection than clip-style alternatives, reducing the risk of loose connections over time, especially in panels subjected to vibration, thermal cycling, or service equipment in demanding environments. This makes the Siemens B35000S01 an excellent choice when you need durable, long-lasting protection without compromising on panel space or compatibility.

Tip: For installation, ensure you’re using the correct Siemens matching loadcenter or panelboard to maintain full protection coordination and adherence to NEC guidelines. The B35000S01 is a purpose-built component that aligns with Siemens' design language and electrical specifications, helping you maintain a clean, reliable electrical distribution system.
