1-pole DC bidirectional relay,
Contact system SPST-CO
R400 – High-voltage relays for test benches
Rated insulation voltagebis up to 1,500 V. Continuous currents up to 25 A. Short-time currents up to 200 A.
R411-25-24I series
The compact high-voltage relay R400 has been specially developed for use in test systems. Used there, the relays are required for testing electrical safety. The switching devices isolate all non-active components during the high-voltage and insulation test procedure. As part of the protective conductor test, they switch currents up to a maximum of 25 amps to the test object.
Another area of application for the small switching device is its use as a precharging relay. This is because the relay is particularly advantageous in smaller traction applications or applications with traction batteries when only low precharging currents need to be switched.
Features
- Bi-directional high-voltage relay: for effortless load disconnection regardless of polarity.
- Contact bridge with solid contacts: for uniform contacting, consistently low contact resistance and permanently low power dissipation.
- Modularity: 1 and 2 pole versions. Contact system configurable as normally open or changeover contact.
- Coil drive: with efficient electronic coil control for low pull-in and holding power.
- Easy mounting: DIN rail mounting according to industry standard. Connections for contact system and coil drive with flat tab terminals.
