Product Description
WJ Furse 7TCA085400R0070 ESP SL30L/4-20 Surge Suppressor Unit is a signalling application surge protector designed for twisted pair data lines. It offers an ultra-slim, low-resistance design that delivers enhanced surge protection with minimal impact on signal quality. The device features a maximum voltage rating of 36.7 volts and can withstand surge currents up to 20 kiloamperes, making it suitable for environments subject to electrical transients.
Constructed with a sturdy, flame-retardant polycarbonate housing, this unit is designed for installation on DIN rails, facilitating easy mounting and maintenance. Its very low let-through voltage between lines and low inline resistance of just 1 ohm ensure that high bandwidth communication is maintained without interruption or degradation.
This model includes LED indication to provide visual feedback on operational status, enhancing monitoring capabilities in industrial and commercial settings. Grounding is accomplished via the DIN rail foot or an additional 4 mm² earth terminal to ensure safety and compliance with electrical standards.
Designed to operate reliably in harsh conditions, this device withstands temperatures ranging from -40°C to 80°C. It meets international safety and performance standards EN 61643-21 and IEC 61643-21, and carries IECEx certification, making it suitable for use in hazardous area installations.
The surge suppressor is ideal for industrial, manufacturing, telecommunications, and automated control systems where transient voltage suppressors are essential for protecting sensitive electronics from voltage spikes and surges.
