Square D® Motorpact medium voltage motor controllers are designed and manufactured to tackle the toughest power and process control challenges. Our motor controllers feature industry-first innovations that provide unmatched performance, high reliability, low maintenance and exclusive technologies. Motorpact medium voltage motor controllers are designed to provide the most efficient means to control and protect a wide range of applications and may be configured for motor starting, transformer feeders, capacitor feeders or future spaces.
Motorpact controllers are designed to meet or exceed the standards for NEMA ICS3 Part 2, UL Standard 347, and IEC 60470. UL and cULus labels are standard.
Enclosures are available in Type 1, 1A, and 3R and feature the smallest footprint in the industry at 14.75 inches wide. Enclosures that are 20-inches and 29.5-inches wide are also available for FVNR.
Controller voltage ratings range from 2.3–7.2 kV vacuum contactors feature a drawout design and have ratings of 200, 400, 450, and 720 amperes.
By combining the latest developments in circuit breaker technology with world-renowned quality, Powersub vacuum substation circuit breakers are the most advanced medium voltage circuit breakers available. The Type FVR Powersub circuit breakers include
arc-resistant construction and are built to comply with ANSI standards.
The arc-resistant design takes safety to the next level. In the event of an arc, the arc-resistant construction provides increased safety for personnel working in proximity of the breaker by venting resultant arc by-products and ionized gases
upward and away from exterior panels that otherwise may not remain intact and in place. The Powersub circuit breakers also provide superior protection as a result of their high speed operation. You can expect long life from the product as the vacuum interrupter contacts are protected from corroding elements and contamination.
