1V ircuit Breakers Timers Relays & Sockets Signaling Lights Switches & Pilot Lights Time Delay urve and Ambient Temperature 1V circuit breakers employ a hydraulic magnetic tripping system, where the rated current (trip current) is not affected by ambient temperatures. But the time delay may vary with the oil viscosity in the oil dash pot. Lower oil viscosity at higher temperatures results in a shorter delay, whereas at lower temperatures the delay will be longer. Temperature orrection urve The time delay curves on the preceding page are measured at 40. With reference to the following curves, time delays can be corrected according to ambient temperature. hange of Time Delay (%) 600 500 400 300 200 100 80 60 40-20 -10 0 10 20 30 40 Ambient Temperature ( ) The time delay is based on an ambient temperature of 40. Time delays at other temperatures are corrected according to the temperature correction curve. The time delay of the instantaneous time delay curve (S) is not affected by ambient temperature. 50 60 70 Relay Trip (Voltage Trip) at 25 Tripping Voltage For D Resistance (Ω) 24-48V 100.0 Tolerance: ±25% Inertial Delay Inertial delay is designed not to trip on a non-repeating single pulse of 20 times the rated current (peak value) for a duration of 8ms. In addition, circuit breakers equipped with inertial delay do not respond to high inrush currents caused by transformer or lamp loads, but perform the specified interruption on subsequent overcurrents.

Therefore, when circuit breakers with a small rated current are used, voltage drop should be taken into consideration. Internal resistance also varies with time delay curves, which should also be considered during installation.
