With a 100 A current rating across three poles and a 240 V nominal rating, this breaker helps you confidently safeguard feeders and equipment in commercial and light industrial environments.\u003c\/p\u003e \u003ch3\u003eWhy this 3-pole design matters\u003c\/h3\u003e \u003cp\u003eIn a 3-phase setup, all three live conductors share protection. The EB3100S disconnects all poles when a fault is detected, preventing partial protection that can leave equipment exposed and panels vulnerable. This makes it ideal for three-phase motors, pumps, HVAC compressors, and large lighting installations that run at 240 V.\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree-pole configuration:\u003c\/strong\u003e protects all three phases simultaneously for complete circuit protection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100 A rating:\u003c\/strong\u003e suitable for feed circuits and distribution to moderate-to-heavy loads without nuisance trips.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e240 V nominal:\u003c\/strong\u003e designed for standard commercial\/industrial 3-phase power systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliable Siemens engineering:\u003c\/strong\u003e built for durable performance in demanding environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e intended for use in Siemens panelboards and compatible enclosure systems designed for EB-series devices.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eIdeal use cases\u003c\/h3\u003e \u003cp\u003eThe EB3100S excels in settings where robust 3-phase protection is critical.
