Instantaneous tripping time of relay protection
How it Works: Instantaneous protection trips immediately upon detection of an overcurrent, without any time delay. Fastest Response: It's the fastest response. No Time Delay: The trip happens. Instantaneous overcurrent protection is where a protective relay initiates a breaker trip based on current exceeding a pre-programmed “pickup” value for any length of time. Often includes directional. If the operating time of the relay is 20ms +/- 30 ms, don't you plan on it operating in 50ms? Maybe, I am not reading that right. I don't know what breakers you are using but from what I see.

Relay protection time characteristic curve
The time current characteristic curve in overcurrent relay is one of the most important tools used to understand how a protection relay behaves when fault current flows through a power system. Ensure that the minimium, un-faulted load is interrupted when the protective. Selective short-circuit protection can be achieved in different ways, such as: Time-graded protection Time- and current-graded protection A straightforward way of obtaining selective protection is to use time grading. There are three main types of overcurrent relay: (1) Instantaneous, (2) Time-Dependent (Definite time or inverse), and (3) Mixed (Definite time and Inverse).

Household Electrical Relay Protection
Some units include time-delay settings to prevent nuisance trips from short blips. Digital/microprocessor relays offer precise adjustment, logging, and self-tests. Protective Relay Definition: A protective relay is an automatic device that senses abnormal conditions in electrical circuits and triggers actions to isolate faults. Undervoltage relay: This relay watches for voltage dips, and if things drop too low, it cuts off power to avoid stressing motors and electronics. The terminals of the relay mainly include; common, coil, NO (normally open) & NC (normally closed).
