Series of dc contactors for protecting electrical circuits
Thomas & Betts’ Jennings JEV250, JEV400 and JEVB500 series of dc contactors are designed to extend mechanical and electrical life and are designed to protect the electrical circuit whether it is charging or discharging. Jennings JEV400 series dc contactors are rated at 450V and are designed for power station communications as well as solar power, wind power, smart grid, and electric-vehicle applications. Jennings JEV250, JEV400 and JEVB500 dc contactors offer a mechanical life of up to 2 million cycles. Other features include energy savings that are achieved by controlling the inrush current with a constant current inside the magnet coil, even when the supply voltage changes; and lowered noise emissions, with a maximum operation noise level of 60 decibels (dB).
