Overview
The Square D TVS120LC20 Surgelogic Transient Voltage Surge Suppressor (TVSS) is a single-phase surge protective device (SPD) designed to shield microprocessor-based equipment, PLCs, motion controllers, and industrial instrumentation from transient overvoltages. The LC Series is a surge protection filter that offers high-quality surge protection and noise filtration, and can be connected to the incoming power source (20 A or less) to protect the control panel components from the outside environment.
Key Features
- Series Hybrid Protection: Uses series hybrid circuit type with three surge suppression paths (line-to-neutral, line-to-ground, neutral-to-ground)
- High Surge Current Rating: 40 kA maximum surge current capacity
- Compact Type 1 Enclosure: Type 1 enclosure design with 1 lb product weight
- Flexible Connection Options: Spade lug terminals sized for 22 to 12 AWG wire and DIN rail or flange mounting
- Industrial-Grade Protection: Ideal for panel builders as well as manufacturers and integrators of instrumentation cabinets for industrial, medical, and commercial applications
