For more than a half-century, ATC Diversified Electronics, a division of Marsh Bellofram, has offered some of the industry’s highest-reliability AC current monitors, motor and pump protection, isolated switches and alternating relay products.

As a leader in solid state control products, the division was the industry pioneer in the first phase monitor relay, designed to protect three-phase equipment from adverse conditions such as phase loss (single phasing), under voltage (brown-outs), and phase reversal (improper sequence). Continued investment in new product R&D and continuous quality improvements allows the ATC Diversified team to offer market-leading technologies, keeping pace with the needs of an evolving industrial marketplace.
