ATC

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 is an 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).
