Altran Magnetics AEV250 High-Voltage DC Contactors

Altran Magnetics AEV250 High-Voltage DC Contactors are 500A+ and 1000VDC DC contactors with an inert gas-filled arc chamber for high-voltage switching. The Altran Magnetics AEV250 features a small, low-profile design with low noise while carrying or switching loads. The series is safe for use in explosive environments, with no arc leakage due to its hermetically sealed design. The AEV250 features an economized coil for low power consumption and is mountable in any orientation without compromising performance.
