OSHA Occupational Safety and Health Administration
PCB Printed Circuit Board — A surface for the mounting and interconnection of
electronic components.
REPO Remote Emergency Power Off — A switch, separate from but wired to the
regulation unit, when pressed, shunt trips the Main Input Circuit Breaker.
Thermal REPO Thermal Remote Emergency Power Off — A thermal activated switch, separate
from but wired to the regulation unit, which reacts to a predetermined
temperature range by shunt tripping the Main Input Circuit Breaker.
Reset (a circuit breaker) Move the breaker first to OFF position, then to ON. This step required after the
breaker has ”tripped”
SCR Silicon-Controlled Rectifier
Shunt Trip A device for tripping a circuit breaker indirectly, using a signal to activate a
solenoid, instead of directly, because of an overcurrent condition.
Trip A circuit breaker in an open position as a result of an overcurrent condition to the
load, or as the result of a remote trip command (shunt trip). In a tripped
condition, power to the load is off. The tripped circuit breaker position differs
from the off position in that the breaker must first be turned to the OFF position
before restoring power to the load.
