CITEL T2 AC Surge Protector

Surge protector for T2 AC networks - CITEL AC-DS44-230 operates at four discharge speeds with a current In = 20kA (8/20µs), utilizing a varistor block as the main protective element in each module. Designed for installation in low-voltage switchboards as the second stage of protection against induced surges. It is also available in a version with remote signaling capability (-S). Advantages of the T2 AC-DS44-230 surge protector: • Rated voltage Un=230V AC • Rated discharge current (8/20µs) In=20kA per discharge. • Maximum discharge current (8/20µs) Imax=160kA • Nominal frequency fn=50-60Hz • Leakage current < 1mA • Response time ta < 25ns Technical data for T2 AC-DS44-230: AC Voltage [V] 230V AC Maximum continuous operating voltage Uc [V] :255V AC Nominal frequency - fn [Hz] :50-60Hz Short circuit withstand rating - IISCCR [A] 25000A Thermal disconnector :internal Maximum fuse [A] :up to 125A (gL/gG) Residual-current device (if present in the network) :type "S" or time-delay Conductor cross-section :2.5-25 mm² (35 mm² Fault indicator :mechanical, red Remote signaling (FS) :potential-free changeover contact Maximum switching capacity :250V/0.5A (AC) / 30V/2A (DC) FS connector cross-section :single-/multi-core max. 1.5 mm² Mounting :TH35 mounting rail Operating temperature range: from -40 to +85°C Degree of enclosure protection: IP20 Enclosure material: PEI UL-94-V0 plastic Control standards: PN-EN 61643-11 - Poland Type 2 surge protector EN 61643-11 – Europe: Low Voltage SPD - Test Class II UL1449 – USA: Low voltage SPD
