Q1: What is the difference between P switch and T switch?
A: P switch is a load isolation switch, mainly used for the opening and isolation of the main circuit load, only 3P and 3+N, can add auxiliary contacts; T switch is a multi-function switch, the contact sequence is diverse, modular contact unit, can be any combination of customized products, such as: on-off switch, transfer switch, reversing switch, star delta switch, stepper switch, multi-speed switch and instrument control switch and so on.
Q2: Can the cam switch T be used as a load disconnector?
A: Yes. The T-switch is used as a load disconnector and has exactly the same function as the P-switch.
Q3: Can the T switch be equipped with an auxiliary contact module?
A: T switch products can not be equipped with auxiliary contact modules, T switch to select the auxiliary contact function, in order to select the contact sequence, together with the main contact.
Q4: What is the function of T0-3-15683/EA/SVB switch and what is the contact?
A: This type of switch is the main switch of the line, which can directly interrupt the corresponding motor and other loads. The number of contact modules is 3 layers, and the total number of contacts is 6 pairs, including 3 pairs of main contacts, 2 pairs of normally open and 1 pair of normally closed auxiliary contacts.
Q5: What type of T/P switch can realize the padlock function?
A: Regardless of whether it is a P switch or a T switch, the padlock function can only be realized as the main switch with the ON/OFF function. That is to say, if the model contains the description of SVB or SVB-SW, the padlock function can be realized.
Q6: What is the difference and model characteristics between the general main switch and the main switch with emergency stop function?
A: Generally, the main switch is used for power control and isolation in a local or subsystem and single load in a certain distribution area, and the general handle is designed in black and gray color, which is described by SVB-SW in the model; The main switch with emergency stop function is higher than the general main switch, generally in a zone, independent system, only one of this switch, and the standard color of the handle is designed to be red and yellow, that is, the model contains the word SVB. The red and yellow warning signs mean that in an emergency, it is easy to identify and quickly cut off the power supply.
Q7: Can the handle of the transfer switch T0-1-8210/E be locked?
A: No, you cannot. The transfer switch is not an ON/OFF main switch and cannot be equipped with an SVB or SVB-SW handle, so it cannot be padlocked.
Q8: Can the T/P switch be available in ATEX explosion-proof version?
A: Not available at this time. When customers need to integrate the switch with other components in the system, the explosion-proof issue should be considered in a unified manner.
Q9: What is the maximum number of contact modules that can be made by the T switch? What is the total number of contacts?
A: The T switch can be retrofitted with up to 11 layers of contact modules, bringing the total number of contacts up to 22 pairs.
Q10: Can I add 2 pieces to the switch auxiliary contact NHI11-P1/P3E with P1 and P3 flush mounting mode?
A: You can add 2 pieces, and you can add one piece on the left and right, which can achieve 2 normally open and 2 normally closed.
