Relay is designated to monitor 3-phase circuits. Type N230 controls voltage towards neutral wire, type A400 controls inter phase voltage. Relay can monitor voltage in two levels (overvoltage / undervoltage), phase asymetry, phase sequence and phase failure. Each faulty state is indicated by individual LED.
Time delays t1(fixed) - when changing from faulty to normal state or when de-energized and t2 when changing from normal to faulty state. These delays prevent incorrect conduct and oscillation of output device during short voltage peaks in the main or during gradual voltage decline into normal.
Set upper level Umax in range Us×(1+5%)-Us×(1+30%) and lower level Umin in range Us×(1-5%)-Us×(1-30%) Umax. In case any phase passes this range, after a delay which eliminated short voltage peaks, contact opens. Output contact again switches after returning back into monitored voltage range and exceeding ?xed hysteresis . In case of failure of two or three phases, the relay is deactivated immediately regardless of the set delay t2.
Monitors correctness of phase sequence. In case of unwanted change output contact breaks. In case of energization of a device with incorrect phase sequence, contact stays opened.
Rate of assymetry between individual phases is set in a range of 5-15 %. In case set asymmetry is exceeded, output relay breaks and LED indicating asymetry shines. Delays t1, t2 and hysteretic are applicable when returning to normal state.
