ECK High-Voltage DC Contactors

TE Connectivity's (TE) ECK High-Voltage DC Contactors offer high performance in terms of electrical endurance, allowing a switching voltage of up to 1,000VDC. These contactors enable bidirectional loads for main contacts and are hermetically sealed with ceramic sealing technology.  The contactors feature a 0.4Ω maximum contact resistance at 30VDC, 30ms maximum operating time and 10ms maximum release time. The series complies with the DC-1 utilisation category in IEC 60947-4-1. TE ECK high-voltage contactors offer an innovative and reliable solution for electric vehicles, electric forklifts, battery storage systems, photovoltaic inverters and automated guided vehicles (AGVs).
