Lightning and surge protection SPD/S1.1 OVR KNX Surge protection device (SPD).
Combined Category D, C, B tested SPD (to EN/IEC 61643) suitable for protecting KNX i-bus systems against transient overvoltages (surges). For use at boundaries up to Lightning Protection Zone LPZ 0 to protect against flashover (typically the service entrance location) through to LPZ 3 to protect sensitive electronic equipment connected on the KNX i-bus system.
Features & benefits
- Surge protection between all KNX lines (line to line, line to earth) capable of handling partial lightning currents as well as allowing continual operation of protected equipment
- Superior surge protection performance for sensitive KNX line to line mode
- Repeated protection in lightning intense environments
- Simple in-line or series plug-in installation with convenient earth connection and DIN rail mounting
- Push button for protection health-check LED indication
- Strong, flame retardant housing
- Certified to latest IEC 61643:21 SPD and KNX 9.1FV standards
Application
- • SPD/S1.1 (OVR KNX) SPDs are applied to KNX i-bus data lines for each KNX system within each distribution panel as shown in the application diagram. Additional power
SPDs are also required.
