product description

This product is a new generation of automatic transfer switch that uses the coil to operate instantaneously. Compared with the switch that is traditionally converted by motor drive, the structure has a simple structure, the conversion action speed is fast, the time is less than 80ms, and the main contact system is single-pole double-throw ( The V-type mechanism does not cause the two power sources to be turned on at the same time even under extreme conditions.

Model meaning

In order to meet the requirements of individual users, the internal circuit of the original switch can be adjusted to achieve the controller control requirements. However, this device has no manual function and no adjustable specific delay. Therefore, please pay attention to the selection of each user.

NMHK type two-stage design mode

The NMHK type two-stage power conversion disconnector is rated for AC400V.

The rated current is: 16A, 25A, 32A, 40A, 63A, 125A, 160A, 200A, 250A, 400A, 630A, 800A, 1000A, 1250A, 1600A, 2000A, 2500A, 3200A, 4000A, 5000A, 6300A, which has two poles , three poles, four poles.

We refer to 16A-125A as "N" type; 160A-400A as "T" type; 630A or more as "M" type;

Features

1. Both current conversions are operated by one electromagnetic coil.

2. Simple structure and convenient maintenance.

3. The contact capacity is large, and the new movable contact mechanism is stable and reliable, and has strong overload capability.

4, eliminated the extra conductive parts, the structure is simple and long life.

Manual operation method and precautions

The electric operation of the transfer switch electric appliance can ensure that the Ue conversion is normal at 85% Ue~110%, but for manual manual operation, because of the difference in strength and speed of the personnel, it is impossible to ensure that when the manual manual operation switch is used for load conversion, Silver contact consumption, fusion welding, etc. may occur. Therefore, in manual manual operation, please perform the following conditions (note the full gate indication).

1. When the controller has no operating power.

2. When the bus output is no load.
