158 Series - High Voltage, Open Style Relay
SPDT - Double Make / Break, 200mA
For HIGH VOLTAGE. Designed with a unique double make / break contact arrangement the 158
series is capable of switching loads up to 1kVA at 5,000 volts. An extra wide contact gap provides
excellent arc resistance between contacts. The double break configuration ensures double gaps
achieved at higher speeds than single break contacts to extinguish arcs.
