onboard

Electrical equipment; Circuit breakers

installed and functional within a vehicle: on-board computers for aircraft.

Short-circuit delay (STD)

Electrical equipment; Circuit breakers

The length of time the circuit breaker will carry a short circuit (current greater than the short-circuit pickup) before initiating a trip signal.

Short-circuit pickup

Electrical equipment; Circuit breakers

The current level at which the circuit breaker shortcircuit delay function begins timing.

Sensor size

Electrical equipment; Circuit breakers

Maximum ampere rating possible for a specific circuit breaker, based on the size of the current sensor inside the circuit breaker. Sensor size is less than or equal to frame size.

Sensor plug

Electrical equipment; Circuit breakers

A component used with the MICROLOGIC trip system to set the sensor size of a circuit breaker.
