Contactors Series LTNS
The LTNS contactors, characterised by a nominal voltage of 750V, are available in a wide range of current ratings, from 80A up to 1300A (up to 3). They can be configured in any combination of Normally Open or Normally Closed poles , with a common rating.
These contactors have been designed starting from the N series electric arc management concept, grafted on the light and compact structure of a rail unit, developed around the control electromagnet.
LTNS series were developed to answer to the constantly increasing market need of reduced dimensions and weight, taking most of the huge know-how in designing and manufacturing of industrial bar mounted contactors.
General Characteristics
- The extra heavy duty flexible line, up to 1000VDC/AC application, up to 1500A/pole
- Stationary application only, derived from LTHS line
- 1-2-3 pole configuration, NO and NC poles indirect or direct arc blow out options available
- Flexible control and auxiliary contacts options, high unit customization possible
Applications
- Transit and railway systems
- Control of cranes
- Rolling mills
- Mining equipment
- Renewable energy

Contactors Series LTHH/LTE/LTP
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.
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).
General Characteristics
- The long experienced extra heavy duty flexible line, up to 2000VDC/AC application, up to 1500A/pole
- On board and stationary application
- Combination of up to 3 NO or NC poles and auxiliary contact options
- High unit customization possible
Applications
- Auxiliary converter input
- Filter pre-charging
- Capacitor discharging
- Heating/Air conditioning systems
- Line contactor
- Train supply line
- Resistors based traction systems, for starting and braking of electric motors

Contactors Series LTC
LTC series are based on a standard concept, but a very high level of customisation can be achieved by replacing few key components. The breaking circuit is equipped with permanent magnets to work efficiently both with high and low currents.
LTC series are suitable for all those applications on board trains which demand a small, smart device. Their design encourages applications where high operating frequencies and small available spaces are important requirements.
General Characteristic
- The modern and compact heavy duty line, up to 4000VDC/AC application, up to 1000A/pole
- On board and stationary application
- 1-2-3 pole configuration mostly available, NO and NC poles, permanent magnets or indirect arc blowouts
- Flexible control and auxiliary contacts options, customization possible
Applications
- Auxiliary converter input
- Filter pre-charging
- Electromagnetic brakes
- Heating/Air conditioning systems
- Line contactor

Contactors Series LTHS
The LTHS series of contactors displays a traditional design which enables them to withstand the highest current ratings in harsh working conditions.
To accomplish most of the possible applications, all the LTHS series contactors can be manufactured in single or multipolar form and, upon request, allow a very high degree of customisation. For example, versions with normally open or normally closed poles are manufactured, and mechanical latching can be supplied.
General Characteristics
- The long experienced extra heavy duty flexible line, up to 2000VDC/AC application,up to 1500A/pole
- On board and stationary application
- Combination of up to 3 NO or NC poles and auxiliary contact options
- High unit customization possible
Applications
- Line contactor
- Power or auxiliary converter input
- Filter pre-charging
- Traction motors on-load disconnection
- Electromagnetic brakes
- Heating/Air conditioning systems

Contactors Series N
The N series contactors are characterised by modular design so that their configuration can be tailored to the specific requirements of each application. In fact, the pole ratings cover a wide range, from 85A up to 6000A, and can be mounted side by side regardless of their size and number on a customisable length shafts set, this way offering custom solutions to a wide range of technical needs.
These contactors are designed and tested according to the standard IEC 60947-4-1. They provide excellent operational performances, making them the best choice for high power load connection, often covering the function of a fault clearing protection device.
General Charateristics;
- The bar mounted modular extra heavy duty line, up to 1000VDC/AC application, up to 6000A/pole
- Stationary application only
- Up to 6 pole configuration, NO and NC poles direct arc blow out various aux contacts options
- Flexible control and adjustment configurations, total unit customization possible
Applications- Transit and railway systems
- Power generation
- Control high power motors
- Heavy industries
- Crane Control
