LTHM/P-U/D Line disconnectors feature a modular design to support any combinations of max 4 NO, NC and CO poles with electric motor or pneumatic control. The poles may be connected in parallel for higher current ratings. The short circuit withstanding capability is exceptional (> 140 kA).

• Ratings up to 4000 VDC/AC and up to 3000 A/pole applications
• Single pole or Change over Disconnector
• Modular-Multipolar up to 4 poles
• Category / Operational Frequency class : A4 / C3
• Designed for applications up to OV3, PD3
• Main terminals positions: D, U, DC or CO type
• IEC60077 compliant

• Well-known extra heavy duty line for up to 4 kV systems
• LTHM Line power connection layouts:
  • D version (IN and OUT on opposite sides) for NO, NC or CO type, up to 4 poles
  • U version (IN and OUT on the same side) for NO or NC poles, up to 2 poles
  • DC version (IN and OUT on the same side, one above the other) for NO and NC poles, up to 4 poles
  • CO version (IN and first OUT on the same side, second OUT on the opposite side) for NO and NC poles, up to 4 poles
• Up to 4 poles: 800A or 1500A rated. Every pole may have 1 NO or 1 NO+1 NC, or 1 CO contacts.
• The contact technology, based on multi-finger jaws, enables LTMH line disconnectors to withstand the worst dynamic currents foreseen in railway and industry applications.
• Electric contacts based on LTHM/LTHP concept, providing exceptional short circuit capability, up to 180 kA
• Most compact design can provide size, weight and cost optimization
