The TRS4-D20 provides enhanced Type 2 surge protection for AC networks needing stronger transient suppression than basic entry-level models.
With 10 kA nominal and 20 kA maximum discharge capability, it offers dependable MOV-based performance for commercial and mixed-use facilities where switching surges and induced overvoltages occur more frequently.
The pluggable module enables safe and rapid replacement without disconnecting wiring, while the front-mounted red fault indicator ensures instant condition assessment.
Designed to integrate smoothly into DIN-rail distribution systems, the TRS4-D20 delivers reliable voltage limitation and long-term surge-handling durability.
Applications
Commercial and office AC sub-distribution boards
Equipment protection in buildings with moderate surge exposure
Protection of HVAC units, lighting circuits, and automated systems
Projects requiring coordinated Type 2 protective stages
Installations with maintenance schedules requiring easy module change
