Characteristics: pages 100 - 102
Effective protection for circuits highly sensitive to “high frequency” interference. For use only in cases where the voltage is virtually sinusoidal, i.e.
less than 5% total harmonic distortion.
Voltage limited to 3 Uc maximum and oscillating frequency limited to 400 Hz maximum.
Slight increase in drop-out time (1.2 to 2 times the normal time).
Protection provided by limiting the transient voltage to 2 Uc max.
Maximum reduction of transient voltage peaks.
Slight increase in drop-out time (1.1 to 1.5 times the normal time).
No over voltage or oscillating frequency.
Increase in drop-out time (6 to 10 times the normal time).
Polarized component.
Protection provided by limiting the transient voltage to 2 Uc max.
Maximum reduction of transient voltage peaks.
For satisfactory protection, a suppressor module must be installed across the coil of each contactor.
From LC1D09 to D38 and LC1DT20 to DT40, dc and low consumption 3-pole contactors are fitted with built-in suppression as standard.
Clipping-on makes the electrical connection. The overall size of the contactor remains unchanged.
Mounting at the top of the contactor on coil terminals A1 and A2.
