The LTHH 40 contactor from the Microelettrica Scientifica LTHH/LTE(P) series is designed for high voltage applications, supporting up to 4000VDC/AC and 1300A per pole. It features a compact design suitable for environments where space is limited, such as railway vehicles. The contactor can be configured with normally open or normally closed poles and is available with both electric and pneumatic control options. It is equipped with an indirect blow out circuit, making it capable of handling both high and low currents at frequencies up to 1500 Hz. The DC control coil operates efficiently without the need for an economy resistor, providing flexibility for various applications including auxiliary converter inputs, heating systems, and traction systems. The LTHH 40 is part of a series that sees over 10,000 units delivered annually for significant projects worldwide.
The Microelettrica Scientifica LTHH/LTE(P) series contactors for electric traction are supplied to railways and underground systems throughout the world.
Where high voltage ratings are required, the LTHH series contactors are the right solution. The creepage and clearance distances are widely dimensioned for safe application in polluted ambient. Their narrow outline is especially conceived for applications where space is a critical issue - as more and more often happens on railway vehicles.
To meet all the possible applications, they are available both with electric and pneumatic control, and poles can be manufactured in normally open or normally closed configurations. The indirect blow out circuit makes the LTHH contactors suitable to work both with high and low currents and with relatively high frequency (1500 Hz).
The DC control coil operates without economy resistor within a wide working range. More than 10.000 LTHH contactors are delivered worldwide every year for the most important projects.
