AQ-300 Trip Circuit Supervision
Introduction
All four fast acting trip contacts contain build-in trip circuit supervision function. The output voltage of the circuit is 5V(+-1V). The pickup resistance is 2.5kohm(+-1kohm).
Our TRIP+ modules are improved to switch DC circuits. Using reversed polarity or AC voltage can cause the damage of the internal circuits.
3-wire TRIP+ wiring methods
In normal use the injected current from the normally open contact (No) is 1.5 mA. The voltage of this point is maximized at 15 V by a zener-diode.
It is possible to use parallel connected TRIP+ modules. In this case the negative contacts must be common. The injected current from the “No” contacts is 3 mA.
2-wire TRIP+ wiring methods
If it is necessary, you can also wire the TRIP+ modules using only the “+” and the “No” contacts. The injected current from the normally open contact (No) is 1.5 mA.
It is possible to use parallel connected TRIP+ modules. The injected current from the “No” contacts is 3 mA.
If the circuit breaker needs two-pole switching TRIP+ modules can be connected series.
