DR-1 electronic single channel preset over limit circuit breaker (screen built-in)

Product Introduction: DR-1 (CQ-05) Over limit Circuit Breaker can be combined with other main control instruments, used for controlled objects when the main control instrument loses control or the thyristor device breaks down and short circuitsOver temperature or over limit circuit breaker protection. It has the characteristics of good reliability, strong resistance to vibration and interference, and easy installation. It is suitable for cutting off system energy or giving an alarm when the temperature, pressure, etc. of various boxes, furnaces, or environments exceed the set upper limit. This type of over limit circuit breaker can place the control part in a suitable position inside the equipment. Only the digital switch for setting the over limit value needs to be placed on the equipment panel, so the overall feeling of the equipment is good, easy to layout, and versatile.

Main technical indicators:

1. Equipped with sensors and measurement range: K 0-999 ℃; Pt100 0-400℃; Pressure sensors, etc

2. Setting error: ≤ 2.5% F.S ± 3 ℃

3. Setting method: Digital switch setting

4. Return difference: about 1.5% F.S

5. Output contact capacity: AC250V 5A (resistive load)

6. Power supply: AC 220V ± 15% 50Hz, power consumption of about 3W

DR series electronic multi-channel over limit circuit breaker (screen built-in)

Product Introduction: The DR series electronic multi-point over temperature circuit breaker, combined with temperature sensors such as thermocouples, can track and detect the temperature of 1 to 4 objects. When the detection value reaches the set breaking temperature value, the output contact is immediately switched to cut off the heating power supply of the detection object, or the alarm and disaster relief equipment can be connected. Equipped with corresponding sensors, it can also be used for over limit circuit protection of industrial parameters such as humidity, pressure, and flow rate.

Main technical indicators:

1. Number of detection channels: 1-4, 85

2. Open circuit temperature selection: any value within 0-1200 ℃

3. Setting of circuit breaker temperature value: pre-set by the manufacturer

4. Setting error: ≤± 5% F.S 92

5. Return difference: about 2.5% of the full range

6. Circuit breaking contact capacity: 3A 250V AC

7. Installation hole size: 92 × 85

8. Installation method: Built in screen type
