- BrandБолид НВП
Network shielding blockThe shielding block of network BZS is applied in electric networks (~ 220B, 50 Hz) to protection of the equipment of different function (including, household appliances) from high-voltage impulse noise (natural hindrances – storm discharges - technogenic hindrances – power switches), and also to protection against long retension over 250 Century.
- Provides protection against surge voltage (impulses lasting 8/20 microsec) * with an amplitude up to 10 kV without "-burn-out" - safety plugs and protection against long overvoltage more than 250 V at "-burn-out" - one or both safety locks. BZS recovers working capacity after replacement of safety locks.
- Provides indication of availability of voltage output.
|The maximum operating voltage -||250 V|
|The maximum power of loading -||500 W|
|Resistance through passage (network frequency of 50 Hz), no more -||1 Ohm|
|The maximum voltage of operation of protection between two wires of the floating input of 220 V (L) and 220 V (N) or between any wire of 220 V and grounding (with "burn-out" of safety lock(s), network frequency is 50 Hz), no more -||300 V|
|Ultimate stress of impulse noise (8/20 microsec, * without "burn-out" of safety lock(s)) -||10 kV|
|Limiting pulse discharge current (8/20 microsec) * -||6 kA|
|Leading dimensions -||75х75х46 mm|
* - 8 microsec – duration of increase of impulse - 20 microsec – duration of recession of impulse
