PURPOSE OF THE RELAY
 Relay RT-40M is designed for use in circuits of relay protection and automation of power systems as a device responsive to the excess of the allowable current.
 The relay can be used to control overloading motors or other electrical equipment to monitor consumption, current protection, diagnostic of equipment (locking, low or high power consumption).
 
DESIGN OF THE RELAY
 Relay is produced in a plastic case with a unified front connection wires power and switched circuits. Mounting is carried out on a DIN rail  width 35mm (GOST R IEC 60715-2003) or on a smooth surface. To set on a smooth surface, spring locks must be changed in recent holes, fixing a spring lock, which are located on the back side of the case. Terminal design provides robust clamp wires up to 2,5mm2. On the front panel there are: blue indicator of availability current in control chain " ", red indicator of contacts state of built-in executive relay "", regulator of time actuation "t", regulator of threshold actuation "Current%".
 
OPERATION OF THE RELAY
 The relay does not require auxiliary power supply and directly connects to the measured circuit. For the current range of 30A, power is provided by the built-in current transformer. Relay connection is made to terminals E-E1 for range5A, to terminals E-E2 for the current range 1A. To control the current in the range of 30A, a wire with current is passed through the side hole in the case device.
 To control the current value exceeds 30A should apply standard current transformers XX/5A. If the current measured value exceeds the threshold value, the executive relay will turn on after the counting set by potentiometer «t» time delay. If, during this counting, current value returns to ranges of the set value, the work will be continued without switching the executive relay. At decrease current below the threshold, the relay is switched off immediately (without delay).
 Threshold sets by the upper potentiometer in the range of 10 ... 100% of the maximum current range: - 1A, 5A or 30A.
