Pre-stroke - indicates the distance or angle at which the actuator on the limit switch must move before tripping the switch contact Operating Point - Indicates the position of the actuator when the switch contact is moved to the working position Release Point - Indicates the position of the actuator when the contact returns to its original state Differential - ...

The dual-power automatic transfer switch is mainly used in the emergency power supply system, which automatically switches the load circuit from one power supply to another (standby) power supply switching appliance to ensure the continuous and reliable operation of important loads. Therefore, the dual-power automatic transfer switch is often used in important places of electricity consumption.

Uses: X42 series limit switches can be widely used in various types of mechanical equipment, automatic assembly lines and other light and medium load occasions, can detect the object action state, such as presence and absence, movement position, end of stroke, etc. Overview: The switch is mainly composed of switch operating parts, ...

1. In addition to the short-circuit protection function of the fuse, the air switch can also realize the overload protection of the circuit. 2. The fuse is a one-time protection device, which must be replaced once it is blown and is very troublesome, so its reusability rate cannot be compared with the air switch. ...

2P means two poles, which means that this air switch has two connection ports, one to connect to the neutral wire and one to the live wire, which is suitable for single-phase circuit connection, or can also be used to connect two-phase power supply in a three-phase circuit. 3P is the meaning of three poles, there are three connection ports, and all of them are ...

First, the reason for the fault of the induction circuit of the switch button indicator 1. Aging of circuit board: The circuit board of the switch button indicator induction circuit board may be aged if it has been used for too long, resulting in leakage in the circuit, and then the induction failure of the indicator light. 2. Sense ...

1. Protection The most important role of the limit switch must be its protection effect, the limit switch is also known as the travel limit switch, which is mainly used to control the stroke of mechanical equipment and limit protection. In practice, the travel limit switch is installed in a pre-arranged position, and the travel limit switch is installed in a pre-arranged position.

36V is a safe voltage, but it cannot be used as a standard for dividing high and low voltages. There are two ways to divide high and low pressure: 1. According to the rated voltage: the rated voltage is 1000V and below is called low voltage; The rated voltage of 1000V or more is called high voltage. 2. According to the voltage of the equipment to the ground...

1. Common air switch models in the family Common family models: DZ series, C16, C32. C40, C80, C100, C120 and other products, of which C represents the starting current, such as: C32 means that the starting current is 32A, which can drive a 6500 watt water heater, C40 ...

1. Repeated short-circuit test ◆ Test instructions The output of the module is short-circuited in various input and output states, the module should be able to achieve protection or retraction, repeated short-circuits, and after troubleshooting, the module should be able to automatically resume normal operation. ◆ Test Method a ...

What are the uses of air switches 1. The air switch is an important electrical appliance in the low-voltage distribution network and power drive system, which integrates control and a variety of protection functions. In addition to completing contact and breaking circuits, it can also generate short circuits to circuits or electrical equipment. Severe...

1. Determine the type and protection form of the circuit breaker according to the requirements of the line for protection - determine the selection of frame type, device type or current limiting type. 2. The rated voltage UN of the circuit breaker should be equal to or greater than the rated voltage of the protected line. 3. The rated voltage of the circuit breaker undervoltage tripper ...

1. Through the isolation switch, it plays a good insulating role, so that the whole circuit can be safe and secure, and the maintenance personnel or staff also have enough ability to repair the circuit. 2. At the same time, the low-voltage isolation switch can also change the operation mode of the circuit, which is used in the power plant or gas plant.
