T-cam switches and P-block switches are used in a wide range of standard circuits and currents, and the number of combinations of cam switches is virtually unlimited. Different designs, front panels and dedicated switches ensure optimum sensitivity to meet the requirements.
Q1: What is the difference between P switch and T switch?
A: P switch is a load blocking switch, mainly for the main circuit load breaking and blocking application, as long as 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 triangle switch, stepper switch, multi-speed switch and surface control switch and so on.
Q2: Can the cam switch T be used as a load barrier switch?
A: Yes. The T switch is used as a load barrier switch, and its function is exactly the same as that of 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 choose the function of auxiliary contact, in the selection, together with the main contact to consider the contact sequence.
Q4: What is the function of T0-3-15683/EA/SVB 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 complete the padlock function?
A: Whether it is a P switch or a T switch, only as the main switch with ON/OFF function can complete the padlock function. That is to say, if the type contains SVB or SVB-SW depiction, it can complete the padlock function.
Q6: What is the difference and type 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 blocking in a part or subsystem and single load in a certain distribution area, and the general handle is designed in black and gray color, which is depicted by SVB-SW in the type; The main switch with emergency stop function is higher than the general main switch, generally in a regional, independent system, only one of this switch, and the standard color of the handle is designed to be red and yellow, that is, the type contains the word SVB. The red and yellow color is the positive warning sign, which means that in the state of urgency, 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 can't. 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 supplied with ATEX explosion-proof type now?
A: Not available right now. When customers need to integrate the switch with other components, they should consider the explosion-proof problem in a unified manner.
Q9: What is the maximum number of contact modules that can be achieved 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 P11-P1/P3E switch assist for the P1 and P3 leveling device method?
A: It can add 2 pieces, and can add one piece on the left and right, and can reach 2 normally open and 2 normally closed.
Q11: What is the maximum number of connecting rods for the switches of the P1 and P3 rear device methods?
A: Up to 4 sections can be added, each section is 25mm.
Q12: Does the P switch with SVB come with PE grounding and N-wire terminals?
A: P switch types with SVB are equipped with PE ground and N terminal as standard.
Q13: Can the N-pole attachment and auxiliary contacts of the P1 and P3 switches be installed together?
A: It is possible to install 1 standard auxiliary and 1 N-pole module together.
Q14: Can the ON/OFF switch with a small black handle be replaced with a large padlock handle?
A: Yes. If a customer has previously ordered an ON/OFF switch without the SVB or SVB-SW lettering, they can also purchase a unique SVB or SVB-SW handle to complete the padlock function.
Q15: What is the maximum switching current of the exterior device?
A: The exterior device is a complete set of device boxes with IP65 protection level. Its P switch can achieve the maximum P3-100, and some T switches can achieve T8 (275A). In order to complete the exterior device, the customer must select the appropriate cabinet for the above current standards.
Q16: What is the difference between TM switch and T switch?
A: Both are cam switches. TM is more miniaturized and can be used to control a smaller capacity load circuit, which is small in size and saves more installation space. In addition to the traditional thumb handle operation, the TM series is also capable of key head operation.
Q17: Is there a sign sign for the standard type of T/P switch in Chinese?
A: No. As long as: German, English, French, Italian, Portuguese, Spanish and Sweden, etc., other languages need to be customized, or choose blank logo products, by the customer DIY.
Q18: Does Eaton have a P switch for the switchboard installation method?
A: Yes. Eaton has the P1 and P3 series of distribution cabinet units with extension rods up to 100A. Among them, the metal extension rod is available in suitable lengths of 400mm and 600mm cabinet depth. The operating handle is available in SVB series and K series, which are sensitive and optional.
Q19: How to know the IP65 protection level of T/P?
A: The IP65 rating promised by Eaton refers to the level of protection that can be reached by the front of the switch after the standard device, and not in all directions. As for the exterior device, when the customer opens the wiring of the knock-out hole of the box, the corresponding protection level of the glander must be installed to reach the standard.
Q20: What is the scope of product certification for T/P switches?
A: There is no 5-well standard, there is a 6-well standard.
Q21: Can the M22-A4 be compatible with the M22 pushbutton and indicator light from a single head?
A: As a global production line, T/P switches have all the world's mainstream certifications. Such as: CE, VDE, UL, CSA, CCC and all kinds of ship inspection certifications.
