What is a 4-20mA Surge Protector and why do I need one?
A 4-20mA Surge Protector safeguards sensitive instrumentation and control systems that use 4-20mA current loops from voltage spikes, lightning strikes, and electrical surges. It’s essential for protecting sensors, transmitters, PLCs, and SCADA systems in industrial environments.
Can I use a 4-20mA surge protector with any current loop device?
Yes, our surge protectors are designed to work with all standard 4-20mA current loop devices, regardless of brand, including transmitters, controllers, and monitoring equipment.
Does the surge protector require grounding?
Yes, proper grounding is essential for effective surge protection. Ensure the protector is connected to a reliable earth ground to safely divert surge energy away from your equipment.
What level of surge protection does your device offer?
Our 4-20mA surge protectors typically offer protection up to 10kA or higher, depending on the model, ensuring robust defense against industrial-grade surges and transients.
