Siemens 100 Amp 3 Pole Circuit Breaker

A Siemens 100 amp 3 pole circuit breaker is commonly used in commercial and industrial electrical distribution systems to protect three-phase circuits from overloads and short circuits. Designed for applications requiring reliable circuit protection, these breakers are available in different Siemens product families, frame sizes, voltage ratings and interrupting capacities. Selecting the correct replacement requires matching the breaker to the electrical panel or switchgear and verifying its specific model and ratings.
