Selection Guide

Architectural feature

The switch is made of glass fiber reinforced unsaturated polyester molding plastic and manual handle, which has high dielectric performance, protection ability and reliable operation safety.

□ The switch adopts spring energy storage, instantaneous release of the acceleration closing mechanism and contact structure which connects and disconnects multiple parallel breaks at the same time, which improves the electrical performance and mechanical performance of the product.

□ Switches 160A,250A and 400A are designed in a modular design, while 630Ais designed in an integral structure. It can ensure reliable overcurrent and short circuit safety protection during load operation and switching.

口 Switches are divided into 2 poles, 3 poles and 4 poles (3 poles + can open and close the neutral pole).

□ The handle can be directly installed on the switch to operate (called cabinet operation),or can be operated outside the distribution cabinet through an extended shaft (called cabinet operation).

Auxiliary contacts and back wiring can be provided as required

Use the installation instructions

The switch should be installed horizontaly, and the switch should be in the open position before installation.

The switch should be equipped with NT type fuse, whose performance should meet the requirements of GB13539.1 and 1GB13539.2,and the fuse should have the corresponding rated current and short circuit braking capacity, when the switch is used in the motor circuit, the rated current of the fuse is alowed to be greater than the agreed heating current of the switch.

The "L " in installation dimensions refers to the factory-set stand and installation depth, representing the distance from the mounting plate (or foot) to the panel surface. During installation, adjust the square shafts depth within the specified L-range based on the switch-to-cabinet-door distance. If the distance is shorter than the square shaft accordingly. A fter ad justm ent, securely fasten the bolts. This procedure applies when required by users.

For installation depths other than "L, ", please specify at the tim e ofordering.

Detem ine the installation center position of the handle according to the shape and installation size of the switch, open an opening on the cabinet door panel according to the panel opening size (see Figure 5), and then fix the handle on the cabinet door panel.

Turning the handle clockwise closes the switch, while counterclockwise rotation disconnects it. Before each operation, check the switch's status: when in the open position (0),clockwise rotation is required to close the switch; when in the closed position(l), counterclockwise rotation in necessary to disengage it.

Usernotes

The RDH5R series switch must be used with a fuse, which can be provided by the user, but please use a good fuse to prevent excessive temperature rise.

Please indicate the switch model and specification, number of poles and rated current of fuse w hen ordering.
