Ground Fault Relays
Our ground fault relays provide critical protection by detecting current imbalances in commercial and industrial electrical systems. These devices monitor conductors up to 100 amps and trigger automatic disconnects when faults exceed safe thresholds. Designed for both single and three-phase circuits, they ensure compliance with the latest NEC safety standards while protecting equipment and personnel.
Current Transducers
We manufacture precision AC and DC current transducers that convert electrical current into proportional measurable signals. These sensors support monitoring and control applications across various industries, including semiconductor fabrication and industrial heating systems. Available in multiple configurations to accommodate different conductor sizes and measurement ranges.
Voltage Transducers
Our voltage transducers provide accurate voltage measurement solutions for industrial power monitoring systems. These devices convert high voltage signals into standardized low-voltage outputs for safe measurement and control. Essential for maintaining system integrity in commercial facilities requiring precise electrical parameter monitoring.
Technical Support
Our team offers expert technical support for ground fault protection and current sensing applications. We provide code compliance guidance, product selection assistance, and application-specific recommendations. With deep industry knowledge, we help engineers implement effective electrical safety solutions for complex installations.
Custom Solutions
We develop customized current sensing and ground fault protection solutions to meet unique application requirements. Our engineering team works directly with clients to design specialized relays, transducers, and monitoring systems that address specific conductor sizes, environmental conditions, and safety regulations.
