Terminal Blocks, RFI Filters, PC B Blocks, DIN Rail Blocks & Relay Sockets
Curtis Industries takes great pride in 75 years of defining, refining and producing the highest quality EMC filters, EMI filters, terminal blocks and all related products at the very best value available industry wide.
Custom Terminal Blocks
Curtis Industries is the leading terminal block manufacturer. Terminal blocks are electrical connectors used to attach wires in the same circuit, without having to cut or splice the electrical wires. We manufacture a variety of styles including:
- Barrier style terminal blocks
- Built with thermoplastics to withstand hot temperature extremes
- DIN rail blocks
- Available with screw-free or screw connections for easy installation
- PC board terminal blocks
- Available with single or multi-level rows
See all terminal block options from Curtis Industries for more information.

Liquid Level Controls
Curtis Industries liquid level controls sense and control the levels of almost any liquid. Our units are available with fixed or adjustable set points to control levels in fluids with an external circuit resistance of up to 3,000,000 ohms. We offer three main types of liquid level controls, including:
- Forward mode operation
- Models ELS, LCS/LHS, LCF and RSA
- Reverse mode operation
- Model LCR
- Pump and heater level lockout applications
- Model DLC
You can also view our catalog to see liquid level control connection diagrams to select the ideal component for your specific application.
Three Phase Filters
At Curtis Industries, a leading producer of custom, top of the line electrical components and assemblies, our engineers have over 70 years of experience building radio frequency interference filters designed to meet government standards. For the best in three phase filters, we offer F3480/F3600 Filters, featuring:
- EMC solutions up to 600A at 600VAC
- Power applications up to 360kVA
- 2-stage filter line supports Delta and Wye connected loads
- Effective noise suppression in the critical 150kHz-30MHz range
Nearly all electronic devices emit and receive obstructive, unwanted RFI. This interference affects the quality of radio signals, cell phone signals and most other electronics. Three phase filters and other RFI Power Line Filters decrease the radio frequency given off by external electrical sources to acceptable levels, while still allowing the power frequency current to pass through unaffected. RFI filters also protect other electronic equipment from the interference given off by your device. At Curtis Industries, we test our three phase filters and other RFI filters to ensure they meet all government and international safety and emissions requirements.
While smaller electronic devices like computers only use single phase power, the high power loads of large electrical networks utilize three phase power. Applications for three phase filters include:
- Motors and Motor Control Centers
- Facility Filters
- Laser Welders
- Uninterruptible Power Supplies
- Robotics and Automated Test Equipment
- Power Conditioning Units
- CNC Machinery
- Industrial Ovens
Curtis Industries is the best choice for superior Three Phase RFI Power Line Filters, serving worldwide markets through experienced representatives and distributors. To learn more about radio frequency interference, check out our RFI filters resources.
