Siemens V7H3205 Molded Case Circuit Breaker

Siemens V7H3205 Vacu-Break panelboard switch is a 3‑pole, 400 A fusible disconnect designed for commercial and industrial panelboards. It is rated for 240 V AC operation (often listed as 250 V) and accepts Siemens Vacu-Break fusing elements to protect feeders and motor circuits. The unit is about 17 inches wide and 15 inches high, supports conductors from 1/0 AWG up to 500 MCM, and is specified for up to 50 horsepower at 240 V, making it suitable for motor and load-switching in distribution panels. This Siemens component provides a robust, code‑compliant isolation point in switchgear assemblies, commonly used as the main disconnect or sectional switch within fused panelboards.
