Stefan Relays
Stefan Relays
A relay that has contacts that operate when the voltage drops below a set voltage. In case of undervoltage relay if the voltage in the circuit or system is less than prescribed value it will disconnect the circuit with the help of circuit breaker.
Earth Leakage Relays
- Earth leakage relays with trip levels 0.03-3A
- Configurable Earth leakage Time delay from 0-10 S
- Available in two types Din Rail Mount and Panel Mount
- Core Balance Current Transformer with diameter 35mm,50mm,70mm,120mm,150mm, 210mm also, 115x305mm Rec and 150x350mm Rec are available
- LED indication for relay status, CT open, Earth leakage fault & Test/Reset switch feature
Undervoltage relays
- Used for Protection against voltage drops
- Detection of short-circuit faults, etc.
- main function is to sense or detect abnormalities in the circuit
- The relay then sends message to the circuit breaker to break the circuit.
