Czonka 3 EV200 200A, 900V dc N/O

A very high performance hermetically sealed relay capable of switching 200A at 900V dc, although 500A is possible with busbar connections and dependent on voltage. This instrinsically safe relay can operate in harsh conditions with no oxidation or contamination of contacts, including long periods of non operation. An externally mounted coil economiser reduces the holding current and widens the operating voltage range. An auxilliary contact is fitted within the unit to monitor the main contact position. Note for waterproof applications ask for version without economiser see our DEVR20.
