How it protects you and your equipment

The SEQ32100SM’s thermal element handles normal overcurrent protection, while the magnetic element quickly detects and interrupts short circuits. This dual‑mode protection helps minimize damage from faults, reduces downtime, and supports safer, more predictable electrical distribution across your panelboard or loadcenter.

Practical tips for best results

• Pair this 100 A breaker with compatible Siemens OEM loadcenters and panelboards to maintain coordinated protection across the system.
• Verify that the circuit you’re protecting is appropriate for a 100 A rating to ensure optimal safety and performance.
• For new installations, plan circuit grouping and distribution so this breaker feeds only circuits within its rating and thermal limits.
