■Coil Ratings

The rated currents for some of the built-in operation indicator models differ from the values given in this table. Refer to note 5 below.

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/–20% for AC rated current and

±15% for DC coil resistance.

2. The AC coil resistance and coil inductance values are for reference only.

3. Performance characteristic data is measured at a coil temperature of 23°C.

4. The maximum voltage is one that is applicable instantaneously to the Relay coil at an ambient temperature of 23°C and not continuously.

5. For built-in operation indicator models rated at 6, 12, and 24 VDC, add an LED current of approx. 5 mA to the rated currents.

Arc barrier equipped Built-in diode Built-in operation indicator

G2A-432AY G2A-432A-D G2A-432A-N

The arc barrier equipped model is

a relay designed to prevent arc

short-circuiting between phases

and can be used in a circuit which

has potential difference between

phases. The switching power of

such a circuit with potential differ-

ence must be limited to less than

1/2 the rated load when using this

Relay.

The built-in diode model is a relay

which incorporates a diode for ab-

sorption of the reverse voltage

that may be generated when the

coil is de-energized. Because the

release time of this model is long-

er than the standard model, pay

adequate attention to this point in

designing a circuit. Also, pay at-

tention to the + polarity of the coil.

The reverse-breakdown voltage

of the diode is 1,000 V.

The built-in operation indicator

model has a newly added opera-

tion indicator to the conventional

operation indication mechanism

and facilitates operation monitor-

ing without being affected by am-

bient illumination.

With the -N model (rated at 16,

12, 24, and 48 VDC) and -N1

model rated at 6, 12, 24, 48, and

100 VDC), pay attention to the +

polarity of the coil.

Safety Precautions

Refer to Safety Precautions for All Relays.

A DC coil model with a built-in indicator or built-in diode has coil

polarity. Be sure to wire the terminals correctly, otherwise the diode

may be broken or the operating indicator may not be lit. Furthermore,

as a result of the short-circuiting of the built-in diode, the devices in

the circuit may be damaged.

Safety Precautions for All Relays

Refer to the Safety Precautions section for each Relay for specific precautions applicable to that Relay.

■Precautions for Safe Use

Observe the following precautions to

ensure safety.

•Do not touch the terminal section (charged section) of the Relay or

Socket while power is being supplied. Electric shock may occur.

•Never use a Relay for a load that exceeds the contact ratings of the

Relay, such as the switching capacity. Doing so may result in

reducing Relay performance for insulation failure, contact welding,

and contact faults, and might even result in burning or other

damage to the Relay itself.

•Do not drop the Relay or dismantle it. Doing so may reduce Relay

performance and might even result in burning or other damage to

the Relay itself.

•Relay durability is greatly affected by the switching conditions.

Always test the Relay under actual application conditions to confirm

applicability and use the Relay only for the number of switching

operations that will not affect performance. Continued application of

a Relay with reduced performance may result in insulation failure

between circuits or in burning in the Relay itself.

•Do not apply an overvoltage or incorrect voltage to the coil, and do

not wire the terminals incorrectly. Incorrect application may prevent

the Relay from performing its designed function, may affect

external circuits, and may even result in burning or other damage to

the Relay itself.

•Do not use the Relay in atmospheres containing inflammable or

explosive gases. Switching arcs or Relay heating may result in fire

or explosion.

•Wire the Relay correctly according to the Precautions for Correct

Use when performing wiring or soldering. If the Relay is used with

wiring or soldering that is defective, abnormal heating while power

is supplied may result in burning.

Relay Application

•Before actually using the Relay, perform all possible tests to

confirm applicability. Unexpected trouble can occur in actual

operation that would not be anticipated in theoretical planning.

•Unless otherwise specified, all ratings and performances given in

this catalog are for JIS C5442 standard test conditions

(temperature: 15 to 35°C, humidity: 25% to 75%, pressure: 86 to

106 kPa). When testing the Relay in the actual application, use the

operating environment that will exist in actual applications along

with the actual load conditions.

•All reference data provided in this catalog are from measurement

samples taken from production lines and represented in graph

form. Actual values will depend on the application.

•All ratings and performances given in this catalog are from

independent tests. Values will vary for different combinations of

ratings and performances.

■Precautions for Correct Use

Refer to Technical Guide for General-purpose Relays.
