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.

Additional contact configurations and coil options are available – please use the RFQ/RFI tab above to submit your request.
