Series of high-voltage contactors deliver safe and reliable switching performance

TTI Europe now stocks the ECP series of high-voltage contactors from TE Connectivity. The ECP150B, ECP250B, and ECP350B are hermetically sealed and permit bi-directional flow. The series contactors come with a continuous current capacity of up to 500A and a maximum switch voltage of 1500VDC at 1000A in 30ms or less, fulfilling the safety robustness requirements of high-voltage applications, including battery energy storage systems, solar inverters, and EV charging applications.

With a compact form factor of 104mm × 75mm × 108mm, and weighing approximately 1300g, these contactors are easy to handle and incorporate into space-constrained designs. They offer a reliable dual coil design that automatically switches to 5W hold status after about 200ms energisation with 50W coil power, minimising power consumption. The series is supplied with an auxiliary contact to monitor the power/main contact.

The improved insulation distance of the contactors fully meets the DC-1 utilisation category requirements in the UL/IEC60947-4-1 standard. All products within the series are RoHS and ELV compliant with the EU Directives and come with UL, TUV, and CE certifications.

“The push for higher system voltages to improve power density and enhance efficiency while reducing installation costs continues,” says Dermot Byrne, industry marketing director – Transportation at TTI Europe. “The ECP series contactors with high continuous current carrying capacity can be used in a wide range of applications where fast, safe, and reliable emergency disconnection of high DC voltages is required.”
