HZ12 Series Combination Switch 380V Power Disconnect Switch 40A
Power Cut Off Isolator
Product Description:
The HZ12 series power disconnection switch is suitable for circuits
with an alternating current frequency of 50 Hz or 60 Hz and
voltages up to 550 V AC. This switch is designed for the purpose of
disconnecting and connecting the power supply.
Meet the standards: GB/T14048.3, IEC 60947-3.
Product Specification:
| Model | Name | Usage |
| Ordinary Type |
| HZ12-□/01 | basic type power disconnect switch | These switches are used for switching on and off subcircuits and
common circuits. |
| HZ12-□/03 | lockout type power disconnect switch | They are suitable as the main power switch for machine tools, and
they can be locked when in the disconnected position (i.e., the "0"
position). The interlock switch has a mechanism that interlocks
with the electrical cabinet door. |
| HZ12-□/05 | locked interlock type power disconnect switch |
| Emergency Stop Type |
| HZ12-□/06 | emergency stop lockout interlock type power disconnect switch | These switches are used for emergency stop of electrical equipment.
They are locking switches that can be locked in the disconnected
position (i.e., the "0" position). The interlock and unlock switch
has a mechanism that interlocks with the electrical cabinet door. |
| HZ12-□/08.1~5 | emergency stop lockout interlock type power disconnection switch |
| HZ12-□/10.1~5 | emergency stop lockout type power disconnect switch |
Operating Conditions and Environmental Suitability:
●Ambient temperature is -5℃~+40°C, the average temperature during
24 hours couldn't exceed +35°C.
●Altitude: ≤2000m.
●Atmosphere condition:
1.Humidity: Relative humidity of the atmosphere couldn't exceed 50%
when the highest temperature is +40°C; much higher relative
humidity is allowable under the condition of lower temperature, for
example, when the temperature reaches +20°C, the relative humidity
is up to 90%, taking into account the condensation that may occur
on the product surfaces due to temperature changes.
2.Pollution grade: 3.
●Installation condition:
1.The HZ10 series combination switch should be installed in an
environment without significant shaking, impact, vibration, and
without exposure to rain or snow.
2.It should be installed in an environment without the risk of
explosion or substances that could corrode metals and damage
insulation (including conductive dust).
3.Installation category: III.
