Minilec Phase Failure Relay
Service Details:
| Model | MPFR-1 |
| Supply Voltage | 240 V AC |
| Mounting Type | Panel Mount |
| Phase Usage | Single + Three |
| Protection Function | Under Voltage, Over Voltage |
| Contact Rating | 6 A |
| Protection Degree | IP30 |
A Minilec Phase Failure Relay is an electrical protection device that monitors a three-phase power supply to prevent damage to equipment, especially three-phase motors, from problems like phase loss (single-phasing), phase sequence reversal, and voltage imbalance. It works by constantly checking for a valid and balanced three-phase supply; if an unsafe condition is detected, the relay opens its internal switch, cutting power to the machinery to prevent overheating and catastrophic failure.
Electronic Overcurrent Relay
Service Details:
| Current Range | 0.5-5 A |
| Relay Technology | Electromechanical |
| Trip Time Curve | Instantaneous |
| Poles | 1 Pole |
| Mounting Type | Panel Mount |
| Protection Type | Phase And Earth, Phase Overcurrent, Earth Fault |
| Auxiliary Voltage | 220 V DC |
| Frequency | 60 Hz |
An overcurrent (OC) relay is a protective device that detects current exceeding a preset threshold, triggering a circuit breaker to isolate faulty or overloaded electrical equipment. It operates based on magnetic effects to close contacts, offering crucial, fast-acting protection against short circuits and overloading.
Numeric Protection Relays
Service Details:
| Protection Function | Overcurrent |
| Number of Elements | 3 Element |
| Auxiliary Supply | 48–125 V DC |
| Number of Outputs | 2 Outputs |
| Communication Port | RS485, Ethernet |
| Mounting Type | Flush Mount |
| Display Type | LED |
