Siemens V7B3222R Three-Phase Circuit Breaker

Siemens V7B3222R Vacu-Break panelboard disconnect switch is a three-pole, fusible disconnect designed for inside-panel mounting in industrial and commercial power-distribution systems, providing safe, clearly isolated shutdown of three-phase circuits when service or maintenance is required. Rated for 250 V AC and 60 A, the V7B3222R supports up to 7.5 horsepower motor loads and uses Vacu-Break contacts to deliver reliable opening and fault isolation; the unit is built to fit in NEMA 1 panel enclosures for indoor installation. Its footprint is roughly 17 inches wide by 5 inches high with about 6-3/4 inches of depth, making it a compact choice for panelboards and enabling straightforward wiring and fuse integration; it accepts Class R, H, and K fuses for fused protection. With a short-circuit rating up to 200 kA at 240 V, the V7B3222R is intended for distribution configurations where high fault currents must be interrupted quickly, ensuring safe isolation of 3-phase circuits in the factory or facility environment.
