Siemens SEQ40100 100A 2-Pole 240 V Circuit Breaker

Protect your 240-volt electrical system with precision using the Siemens SEQ40100 100A 2-Pole 240V Circuit Breaker. This Siemens part delivers reliable overcurrent protection, designed to interrupt both hot legs simultaneously to keep your panels and connected equipment safe.

Key specifications

• Current rating: 100 A
• Poles: 2
• Voltage rating: 240 V
• Part number: SEQ40100

Why choose the Siemens SEQ40100

• Two-pole design ensures both live conductors trip together, which is essential for safely interrupting 240V circuits and protecting downstream equipment.
• Designed for use in Siemens panels, offering consistent electrical characteristics and predictable, dependable trip performance.
• Durable construction supports steady protection for 100A circuits, helping reduce the risk of overloads and short-circuit damage in critical 240V applications.

Ideal use cases

• Main disconnect or feeder protection in 100A service panels for homes or small businesses that run 240V equipment (such as central AC, water heating, or subpanel feeders).
• Replacement part for Siemens-based electrical systems when a 100A, two-pole 240V breaker is specified, ensuring correct compatibility and safety characteristics.
• Upgrading outdated breakers to a modern SEQ series solution to improve reliability and panel safety.

Practical tips for installation and use

• Verify panel compatibility with SEQ-series breakers and confirm that a 100A rating aligns with the circuit design and load requirements.
• Keep a spare 100A, two-pole SEQ40100 on hand for efficient maintenance and faster replacements during service work.
