Siemens F3B035 35A 3-Pole 240 V Circuit Breaker

Meet the Siemens F3B035 35A 3-Pole 240 V Circuit Breaker—a compact, reliable protection device designed for robust 3-phase electrical systems. Built by Siemens, this part number F3B035 is ready to safeguard your machinery, panels, and distribution networks from overloads and short circuits by disconnecting all three phases together when protection is required.

• Three-pole, three-phase protection: Ensures all lines trip together to prevent phase imbalances and equipment damage.
• 35-amp rated current: Suitable for circuits that draw up to 35 A under normal operation, balancing continuous load with protection against faults.
• 240-volt compatibility: Optimized for standard 3-phase and 240 V distributions found in industrial and commercial environments.
• Siemens compatibility and replacement reliability: Part Number F3B035 is designed for quick replacement in compatible Siemens panels and distribution boards, simplifying maintenance and reducing downtime.
• Durable construction for demanding environments: Engineered to handle daily cycling and exposure typical of control panels and equipment rooms.

Ideal use cases

• Motor control circuits in manufacturing lines and conveyors
• HVAC feeders and processing equipment in industrial settings
• Control panels in automation and packaging facilities
• Power distribution hubs where space and reliability matter

Installation and safety notes: Always shut off main power and follow local electrical codes. This 3-pole breaker is intended for use in compatible Siemens panels and distribution boards. When replacing an existing breaker, ensure the new unit is the correct Part Number (F3B035) and that the panel labeling aligns with a 3-phase 240 V supply. Tighten terminals to the manufacturer’s recommended torque and verify operation with a test procedure after installation.
