Description

The Square D Type VR 1200A 15 kV medium-voltage vacuum circuit breaker is a high-performance power protection device engineered for use in industrial plants, utilities, and commercial electrical distribution systems. Manufactured by Square D (a brand of Schneider Electric), the Type VR series is designed as a modern retrofit or replacement solution for aging oil or air circuit breakers in metal-clad switchgear, helping extend equipment life while improving safety and reliability.

This breaker utilizes advanced vacuum interruption technology, which provides superior arc-quenching capability, minimal maintenance requirements, and long mechanical endurance compared to legacy breaker technologies. With a continuous current rating of 1200A and a maximum operating voltage of 15 kV, the Type VR breaker delivers dependable switching and fault protection for feeders, transformers, motors, and distribution substations. It is commonly supplied in a draw-out configuration, allowing safe insertion and removal from switchgear compartments for maintenance and testing.

The Square D VR breaker supports high interrupting ratings (typically 25 kA to 63 kA depending on configuration) and integrates with protective relays to ensure precise fault detection and rapid isolation of electrical faults. Its rugged mechanical design includes stored-energy spring mechanisms for reliable opening and closing operations, along with optional electric or manual charging systems. Compact dimensions and retrofit-friendly engineering make it suitable for modernization projects where replacing entire switchgear lineups would be costly.

Designed to meet ANSI and IEEE standards for medium-voltage equipment, the Square D Type VR 1200A 15 kV breaker provides enhanced personnel safety, improved system uptime, and long service life in demanding electrical environments such as power generation facilities, petrochemical plants, mining operations, and large manufacturing sites.
