The 1 Phase Overload Relay is a solid state protection relay. It measures current and provides protection against overload,. This is based on a single chip micro controller, with a high degree of programmability. The Unit is supplied preprogrammed for operation and can be directly installed.It provides Voltage and current protection
- Supply Voltage : 230 VAC ± 15 % for Single Phase input
- Output Contact Rating : Pump Output relay 30 Amp. At 230V AC Pump Time Output relay 7 Amps At 230V AC (Potential Free)
- Front Panel : 1. 3 digit, 7 segment LED display (Displays Voltage ‘U’, Current ’A’, Faults-Overload ‘oL’, Undervoltage ‘uU’, Overvoltage ‘oU’)
- 2. 3 Key keypad for programming. ( SET, INCREMENT, DECREMENT)
Note: DECREMENT Key is also used for Fault Reset) - 3. 3 Led indications for controller,
Healthy Indication by Blinking Green LED
Alarm indication by Red LED.
Relay ON indication by Green LED. - Sensing :
1. Voltage sensing with resolution of 1V
2. Current sensing with 0.1A resolution - Alarm/Protections :
1. Over load protection set point user selectable 0.8Ato 30 A.
2. Over Voltage protection set point user selectable 240V to 290V.
3. Under Voltage protection set point user selectable 140V to 220V.
4. On delay set point user selectable 15s to 60s.
5. Over Load trip delay user selectable 1s to 30s. - Dimension : 200mm 90mm x 60mm (H x W x D)
- 1) Healthy: Power on
