MJK Surge And Lightning Protectors
- MJK Surge And Lightning Protectors used in applications where excessive voltages caused by lightning or other transient voltage can be expected.
- MJK Surge Arresters are constructed with dual protection to cover both medium and high surge protection.
- Available in Surge Arrester 2- Wire Panel, Surge Arrester 2- Wire Field, Surge Arrester 3- Wire Panel, Surge Arrester 3- Wire Field, Surge Arrester RS 485 Line Panel, Surge Arrester 230 VAC Panel Mains Arrestor, Surge Arrester PSTN Terminal Connections Panel, Surge Arrester PSTN RJ 11 Connector Panel, Surge Arrester 3- Wire Panel RS232, Surge Arresters For Magflux For Wall Mounting and Surge Arresters For Magflux For Sensor Mounting
- Protects measuring devices from damage by conducting large power surges and short transients effectively to ground.
- Units for protecting of 2-wire / 4 - 20 mA, 3-wire / 4 - 20 mA and telephone lines is available.
- Surge and transient protection in accordance with Class B (intermediate protection) and Class C (primary protection).
- Protection of telelephone lines in regions with lightning.
- Protection of 4 - 20 mA transmitters installed at high / distant locations.
- Protection of 3-wire ultrasonic level meters installed at high locations in regions where lightning often occurs.
- DIN-rail mounting (Panel) or on site mounting (Field).
