For more than 50 years, ATC Diversified Electronics, a division of Marsh Bellofram Corporation 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 3-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.
Products are available with some of the industry’s shortest lead times.

Marsh Bellofram current monitoring relays, available in multiple styles and types, are designed to detect AC and DC over and under current conditions, effectively detecting and preventing electrical shorts conditions and motor jam-ups which can damage equipment and significantly hamper its longer-term performance...
Pump level controls are often employed within municipal water, wastewater and sewage treatment plants, to ensure smooth-running processes and carefully monitored current loads. Marsh Bellofram offers a rugged series of duplexers, triplexers and quadraplexers, designed to ensure equal run time of loads on industrial pumps, motors and related equipment, extending the useful ...
Available in DIP switch selectable socket mount (plug-in) or DIN-rail mounted versions, Marsh Bellofram time delay relays (also known as TDRs or timers) are used to equip industrial machinery, conveyor belts, exhaust fans, heating systems, lubricators, and pump and motor controls with timed sequence delay, soft-start delay or auto-start functions for added machinery and equipment protection.
Power Alerts are designed to reduce the risk of electrical arc flash by pre-verifying the electrical isolation from outside of a control panel.
