Siemens B335H - 35 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens B335H is a 35A, 240V, 3-pole bolt-on molded case circuit breaker engineered to protect your electrical system with precision in panelboards and load centers. Built for reliable branch circuit overcurrent and short-circuit protection, it combines a rugged mounting design with intelligent trip technology to keep your power distribution safe and stable.

• Bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing the risk of loose contacts and arcing in busy panels and during routine equipment operation.
• Thermal-magnetic trip unit delivers stable, repeatable protection by blending time-delayed overload sensing (thermal) with instantaneous protection against high-energy short circuits (magnetic).
• 3-pole, 240V design is ideal for three-phase systems commonly found in commercial and light industrial environments, while still suitable for complex residential service configurations that require robust three-pole protection.
• OEM-load-center compatibility ensures smooth integration with matching Siemens OEM panels and load centers, providing consistent protection curves and reliable performance across your installation.
• Versatile application—apt for upgrading or expanding panelboards, retrofit projects, and new installations that demand dependable 35A protection on 240V circuits in residential, commercial, and light industrial settings.
