Description
RX LB residual current circuit breakers provide disconnection, switching and protection of electrical circuits against earth fault currents. They have an electromechanical residual current release that operates without an auxiliary power supply and automatically disconnects the circuit when the earth fault current between phase and earth exceeds the rated residual operating current IΔn.
- standard type for general use in domestic and industrial installations up to 100 A, AC 230/400 V
- for additional protection against direct contact (IΔn 30 mA)
- for protection against indirect contact and to protect buildings, machinery, etc. against fire or short circuit when the insulation of electrical equipment deteriorates (IΔn 100 mA)
- designed for alternating current
- resistant to nuisance tripping caused by various network disturbances
- colour indication of the ON and OFF positions
- bear the mark
- manufactured to STN EN 61 008
