The high-voltage relay RL42-T is suitable both for very small voltages in the mV range and for voltages up to 4,800 V AC. The device is suitable for industrial use due to its long service life.
The relays are mainly used in safety and function test systems for testing electrotechnical products. For example, several kV are switched for the high-voltage test, while currents of up to 30 A are used for the function test on motors, for example.
