LTHH/LTE/LTP line Microelettrica Scientifica LTHH/LTE/LTP range is renowned for its high-voltage performances and have been supplied for a wide array of applications. The creepage and clearance distances are widely dimensioned for safe application in polluted environments. Their narrow outline is especially conceived for applications where space is a critical issue - as more and more often happens in electrical cabinets. To meet all possible applications, they are available both with electric (LTHH/LTE) and pneumatic (LTP) control, and poles can be manufactured in normally open or normally closed configurations. The direct or indirect blow out circuit makes the LTHH contactors suitable to work both with high and low currents. The DC control coil operates without economy resistor within a wide working range. More than 10000 LTHH contactors are delivered every year for the most demanding projects and applications worldwide. Applications Railway substations Industry contactors Filter pre-charging Motors on-load disconnections Electromagnetic brake control Heating/air conditioning systems Renewable energy GENERAL CHARACTERISTICS ■■ High-voltage heavy-duty range ■■ Designed for switchgear applications according to IEC 61992-60947 ■■ Ratings up to 4000 VDC/AC and up to 1350 A/pole application ■■ Direct or indirect arc blow-out systems available according specific application requirements ■■ Multi-pole assemblies, NO or NC poles ■■ Very high level of customization available ■■ Suitable for OV3, PD3
