ELECTRICAL CHARACTERISTICS Standard voltages DC (=) : 24V - 48V - 240V (Other voltages and  60 Hz on request) AC (~) :
 24V - 48V - 115V - 230V / 50 Hz TEMPERATURE CLASSIFICATION TABLES AC (~) Solenoids DC (=) Solenoids
A 35,1 W DC, HC coil is available for battery voltages. Range +12% to -28% of nominal voltage (only available on NB construction)
隔爆外殼存在間隙，因電氣設備呼吸作用和氣體滲透作用，
使內部可能存在性氣體混合物。

CONNECTIONS ? Any ATEX approved dia. 9-12 mm cable entry device can be ? tted in the M20 x 1,5: use pre? x NAET or NBET;
 refer to the nameplate for maximum cable temperature (optionally 1/2 NPT / ? 8,5-16 mm, use pre? x NAT or NBT).
Internal and external earthing connection ? The operator can be rotated 360° at 90°
increments to select the most favourable position for cable entry
防爆電磁閥是把設備可能點(diǎn)燃性氣體混合物的部件全部封閉在個(gè)外殼內，

 Actual temperature range can be limited depending on valve operation limits.
OPTIONS ? Non-polarised voltage surge suppressor for DC constructions
，隔爆外殼使設備內部空間與周?chē)沫h(huán)境隔開(kāi)。
