Siemens P1E30MC250C Circuit Breaker Accessories

Siemens P1E30MC250C Circuit Breaker Accessories are an official kit designed to accompany Siemens P1 interior panelboards configured for a 250 A main and up to 30 circuit positions. The kit targets 480Y/277 VAC, three‑phase, four‑wire systems and aligns with the P1 interior family’s 30‑circuit capacity and 250 A rating for commercial installations. The model designation P1E30MC250C identifies the 30‑circuit interior accessory configuration for 250 A service, and Siemens UPB selection materials also reference a related P1E30MC250CT variant, signaling cross‑compatibility with P1 interior configurations. Intended for use with Siemens P1 panel interiors, these accessories support the orderly arrangement and secure mounting of circuit breakers within a 30‑circuit, high‑voltage installation, helping ensure proper enclosure fit, spacing, and compliance with typical 480Y/277 VAC, 3P4W wiring requirements.
