Phase Failure Relay
Reliable protection for three phase systems. These relays sense the negative sequence voltage components of the system supply & these are best suitable for 3 phase loads. - Model: PCON - PF - 5
- It monitors 3 phase supply voltage. Relay remains ON under healthy voltage conditon, and during
- Phase failure or phase unbalance (50V +/- 5V, Fixed) relay becomes OFF (Refer Fig. 20)
- Trip time delay : 2 - 3 Sec, Auto Resetting Mode.
- Supply / Monitoring voltage : 440 VAC 50/60 Hz.
- Relay Output: One change over [ICO). 5A (a 230 VAC / 28 VDC resistive load.
- Size : [70(\V) x 89 (H) x 50 (DJl mm. 35 mm Din Rail or Screw mounting. (Refer Fig. 21)
- Order Code : PCON - PF - 5
