🔌 Relay Short Code Details | PCS-9691 Management Relay | #Shorts

In this short video, we will understand the important protection short codes used in the PCS-9691 Management Relay, which is widely used in transformer, motor, and feeder protection panels ⚡

Each short code represents a specific protection function, such as overcurrent, earth fault, differential, thermal overload, and more.
Here’s a quick overview 👇

🔹 Common Relay Short Codes & Their Meaning:

50 / 51: Overcurrent & Time Overcurrent

50N / 51N / 50G: Earth Fault / Ground Fault

49T: Thermal Overload Protection

46: Negative Phase Sequence / Unbalance

87M: Differential Protection (Motor/Transformer Internal Fault)

66: Intertrip / Blocking Functions

86: Lockout Relay Trip

TCS FAIL: Trip Circuit Supervision Failure
These protection functions help in detecting faults early and safely isolating the system before major damage occurs.
PCS-9691 relay continuously monitors current, voltage, temperature, and trip coil health to ensure reliable operation and advanced electrical protection.
