⭕️6 Adjustable Tripping Settings of a Circuit Breaker You MUST Understand

1️⃣ Continuous Amps (Ir)

🔺Continuous Amps (Ir) varies the level of current the circuit breaker will carry without tripping. Ir is a percentage of the circuit breaker’s nominal rating (In). Continuous amps can be adjusted from 20 to 100 percent of the circuit breaker’s nominal rating.

⭕️6 Adjustable Tripping Settings of a Circuit Breaker You MUST Understand

2️⃣ Long-Time Delay

🔺Long-time delay causes the breaker to wait a certain amount of time to allow temporary inrush currents, such as those encountered when starting a motor, to pass without tripping.

3️⃣ Short-Time Pickup

🔺Short-time pickup is used for selective tripping. The short-time pickup function determines the amount of current the breaker will carry for a short period of time, allowing downstream protective devices to clear short-circuits without tripping the upstream device.

4️⃣ Short-Time Delay

🔺Short-time delay, used in conjunction with short-time pickup, controls the time involved in postponing a short-time pickup trip. This allows better coordination with downstream thermal-magnetic circuit breakers and fuses. A fixed instantaneous trip point of 10,000 amps trips the breaker automatically and overrides any pre-programmed instructions.

5️⃣ Instantaneous Pickup

🔺Instantaneous pickup is used to trip the circuit breaker with no intentional delay at any current between 2 and 40 times the breaker’s continuous ampere setting (Ir).

6️⃣ Ground Fault Pickup

🔺Ground fault pickup controls the amount of ground fault current that will cause the breaker to interrupt the circuit. The adjustment can be set from 20 to 70% of the maximum breaker rating.
