Company Profile:
A communication capability between electronic trip systems and ground-fault relays which permits a short circuit or ground fault to be isolated and cleared by the nearest upstream device with no intentional time delay.
Industry:Electrical equipment
A means of providing equipment ground-fault protection utilizing an external sensor (surrounding all phase and neutral conductors).
Industry:Electrical equipment
Metering method used by the MICROLOGIC® H trip unit where a dedicated metering data chain is separate from the protection data chain so that a greater number of data samples can be used for metering. This increases the number of samples taken per time period, which in turn gives the H trip unit a higher degree of metering accuracy.
Industry:Electrical equipment
The level of RMS symmetrical current that a circuit breaker can carry with the contacts in a closed position for a stated period of time–usually stated in cycles.
Industry:Electrical equipment
A circuit breaker mounted such that it cannot be removed without removing primary and sometimes secondary connections or mounting supports.
Industry:Electrical equipment
An accessory which trips the circuit breaker automatically when the monitored circuit voltage falls below a predetermined percentage of its specified value.
Industry:Electrical equipment
A programmable device which measures and times current flowing through the circuit breaker and initiates a trip signal when appropriate.
Industry:Electrical equipment
A system which consists of a MICROLOGIC trip unit and current transformers.
Industry:Electrical equipment
A button on the trip indicator module used to reset the trip indicator.
Industry:Electrical equipment
A module that mounts directly to the circuit breaker trip unit that displays whether the circuit breaker tripped due to an overload, a shortcircuit or a ground-fault condition.
