FEATURES
• Small size & light weight: size 1/4,
weight 1/2(compared to conventional
contactors)
• No arc space is required: size including arc space 1/9 (compared to conventional contactors)
The arc is not exposed to the outside,
therefore, no arc space is not required.
• Safety construction
The arc is not exposed, therefore, the
contactor is explosion proof and intrinsically safe.
• Quiet: operation noise 1/4 (compared
to conventional contactors).
Along with the above-mentioned miniaturization, the operation noise has been reduced to 70dB, and, in addition, the
operation noise remains unchanged
when a current of 1000A or more is interrupted.
• High contact reliability
The contact part is hermetically sealed
with H
2
mixed gas, hence the contact resistance remains stable regardless of the
ambient conditions.
• Mounting direction is not specified
The weight of the movable parts is light,
and also the restoring force is large,
hence the contactor is relatively unaffected by gravity.
• Line-up of indicator Type (150A Type
only)
A line-up of relays with indicator that can
monitor the relay operation.

NOTES
1. When installing the rela y , al ways use
washers to prevent loosening of the
screws.
Tighten each of the screws within the rated ranges given below. Exceeding the
maximum torque may result in breakage.
Mounting is possible in either direction.
• M8 screw (for 150 A main terminal): 10
to 15 Nm
• M5 screw (150 A, 60 A, 30 A main unit
mounting section)
(60 A main terminal): 2.5 to 3.6 Nm
• M4 screw (30 A terminal): 1.8 to 2.7 Nm
2. The coils (150 A type) and contacts
(30 A, 60 A, 150 A) of the relay are polarized, so follow the instructions in
the connection schematic when connecting the coils and contacts.
Type 150 A has contains a reverse surge
voltage absorption circuit;
therefore a surge protector is not needed.
We recommend installing a surge protector varistor (ZNR) for the 30 A and 60 A
types. Avoid using a diode as this may result in decreased cut-off capability.
3. As a general rule, do not use a rela y
if it has been dropped.
4. Avoid mounting the relay in strong
magnetic fields (near a transformer or
magnet) or close to an object that radiates heat.
5. Electrical life
This relay is a high-voltage direct-current
switch. In its final breakdown mode, it ma y
lose the ability to provide the proper cutoff. Theref ore, do not exceed the indicated
switching capacity and life. (Please treat
the relay as a product with limited life and
replace it when necessary.)
In the event that the relay loses cut-off
ability, there is a possibility that burning
may spread to surrounding parts, so configure the layout so that the power is
turned off within one second.
When using the 30 A type, to prevent increases in the contact resistance, do not
allow switching without any load.
6. Permeation life of internal gas
This relay uses a hermetically encased
contact (capsule contact) with gas inside.
The gas has a permeation life that is affected by the temperature inside the capsule contact (ambient temperature +
temperature rise due to flow of electrical
current). For this reason, make sure the
ambient operating temperature is between –40 and 80°C –40 and +176°F, and
the ambient storage temperature is between –40 and 85°C –40 and +185°F.
7. If the power is turned off and then immediately on after applying the rated voltage (current) continuously to the relay's
coil and contact, the resistance of the coil
will increase due to a rise in the coil temperature.
This causes the pick-up voltage to rise,
and possibly exceed the rated pick-up
voltage. In these circumstances, take
measures such as reducing the load current, limiting the duration of current flow,
and applying a coil voltage higher than the
rated operating voltage (quick start).
8. Main contact ratings in the ratings apply
to when there is a resistive load.
9. If you are using an inductive load (L
load) such that L/R > 1 ms, add surge protection in parallel with the inductive load.
If this is not done, the electrical life will decrease and cut-off failure may occur.
10. When using the 150 A type, mount it
as far away as possible from amateur
wireless transmitters or devices that may
generate large surges.
To prevent malfunctioning due to high
emission levels, it may be neccessary to
take measures for E.M.I., such as adding
a line noise filter or an electromagnetic
shield.
11. Since coil current control is performed, a slight amount of superimposed
line noise may be generated in the input
line system. If this noise must be removed, install a line noise filter.
12. Be careful that foreign matter and
oils and fats kind doesn't stick to the
main terminal part because it is likely
to cause a terminal part to give off unusual heat.
13. A void excessive load applied to the
terminal in case of installing such as a
bus bar etc., because it might give bad
influence to the opening and closing
performance.
