The surge protection magazines of series MTH and MTL are fitted with high quality gas discharge tubes. The are avaibable in variations of 90 V ac and 230 V ac executions. They are designed specially for HVT 71 application of Siemens main distribution in telecom and datat line systems. The integrated fail-safe behaviour protects against dangerous ac influences.
- Fitted magazines for HVT 71
- Magazines are fitted with 10 gas-filled surge arrester (GDT) each
- Stable performance, long service life
- For 5 double lines
