Product Introduction

NDA series chassis truck is with complete stable interlock function. Generally speaking,
five-protection interlock
will be realized through middle positioned unit and chassis truck,

as well as earthing switch, the chassis truck could reach following interlocking performance:

1. Whatever chassis truck is in working position or disconnecting position, when it is in closing state,

handle can't be operated to prevent chassis truck from moving with overload.

2. When chassis truck is in working position, earthing switch can't close, to prevent earthing switch from

closing with electricity.

3. When chassis truck gets back to disconnecting position, and earthing switch is in closing,

chassis truck can't be rotated to working position, to avoid closing with earthing wire.

4. Once chassis truck left disconnecting position, during the process of rotating the handle to move chassis truck

to working position, closing operation can't be proceeded. Closing can only operated when chassis truck
getting working position.

5. There are 2 auxiliary switches installed on chassis truck, the rated current of the contact is 15A, code is S8, S9.

S8 gets 5 pairs of normally-close contacts, when chassis truck is in disconnecting position, S8 auxiliary switch is in
normally-close state.
When chassis truck is in working position, S8 is in breaking state. S9 gets 5 pairs of
normally-open contacts, 
when chassis truck is in disconnecting position, S9 is in breaking state, while when
chassis truck is in working 
position, S9 is in closing state.

6. After chassis truck getting into switchgear, if chassis truck is not in disconnecting position, chassis truck

won't get out from switchgear.
