Circuit Breakers Switches & Pilot Lights NC1V Time Delay Curve and Ambient Temperature Relay Trip (Voltage Trip) at 25°C NC1V 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. For DC Resistance (Ω) Tripping Voltage 24-48V 100.0 Tolerance: ±25% Inertial Delay Signaling Lights Temperature Correction Curve...
