Square D VBF3 Cam Disconnect Switch Fused 690VAC 3 Pole

Product Description

The SQUARE D VBF3 is a fused, enclosed cam disconnect switch rated for 690 volts AC. It is a 3-pole device with a 3NO contact form and accommodates 3 wires. The switch is housed in an enclosed body with an IP20 and IP65 ingress protection rating, making it suitable for both standard and protected installation environments. A handle is included for manual operation. Electricians and industrial maintenance technicians install this switch as a manual disconnect point in electrical distribution and motor circuit applications. It meets CSA, UL, IEC 60947-3, and GL standards.

The VBF3 is suited for use in commercial and light industrial electrical systems where a reliable, manually operated disconnect is required. Typical installations include motor control panels, machinery disconnects, and branch circuit isolation points. The enclosed housing and dual IP ratings allow deployment in NEMA 1 and NEMA 12 rated enclosures. The fused design provides integrated overcurrent protection within the disconnect assembly, simplifying panel layouts where space is limited.
