The Schneider A9C30312 is an Acti9 iTL impulse relay designed for remote and manual switching of electrical circuits. It features two poles with two normally open contacts, a rated current of 16 A, and an operational voltage of up to 250 VAC at 50/60 Hz. The control coil operates at 130 VAC, 50/60 Hz, or 48 VDC and accepts impulse durations from 50 ms to 1 second.
Designed for fixed DIN-rail mounting, the A9C30312 occupies two 9 mm pitches and measures 84 x 18 x 60 mm. It provides local ON/OFF indication, supports illuminated push-button control up to 3 mA, and allows up to five switching operations per minute or 100 operations per day. Tunnel-type terminals accommodate rigid and flexible conductors, while IP20 protection increases to IP40 when the relay is installed within a suitable enclosure.

What type of device is this?
This is an Acti9 iTL impulse relay designed to switch electrical loads through momentary control pulses. It can be operated remotely by a push button or manually at the device.
What is the rated current?
The relay has a rated current of 16 A.
What contact configuration does it have?
It has two poles with two normally open contacts, commonly expressed as 2P and 2 NO.
What control coil voltages can be used?
The control circuit is rated for 130 V AC at 50/60 Hz or 48 V DC. The applied control voltage must match one of these specified ratings.
What is the rated operational voltage?
The rated operational voltage is 250 V AC at 50/60 Hz.
How does impulse operation work?
A short control pulse changes the relay's contact state. Each subsequent pulse toggles the contacts again, allowing a load to be controlled from one or more momentary push-button locations.
What impulse duration does the control circuit accept?
The specified control impulse duration is from 50 milliseconds to 1 second.
What is the maximum switching frequency?
The relay is rated for up to five switching operations per minute and 100 switching operations per day.
Can it be used with an illuminated push button?
Yes. The remote control input is compatible with an illuminated push button drawing up to 3 mA.
Does the relay provide local status indication?
Yes. A local ON/OFF indicator shows the relay's current switching state.
How is the device mounted?
The A9C30312 is designed for fixed installation on a DIN rail. It occupies two 9 mm pitches, giving it an overall width of 18 mm.
What are the device dimensions?
The relay measures 84 mm high, 18 mm wide, and 60 mm deep.
What wire sizes can the terminals accept?
The control terminals accept one rigid conductor from 0.5 to 4 mm² or one flexible conductor from 1 to 4 mm². The power terminals accept one rigid or flexible conductor from 1.5 to 4 mm², including appropriately terminated conductors.
What are the specified terminal preparation requirements?
The specified wire stripping length is 11 mm, and the terminal tightening torque is 1 N·m.
What is the expected electrical durability?
The stated electrical durability is 200,000 cycles for AC-21 utilization and 100,000 cycles for AC-22 utilization.
What operating temperatures can it withstand?
The specified ambient operating temperature range is -20°C to 50°C, equivalent to -4°F to 122°F. The storage range is -40°C to 70°C, or -40°F to 158°F.
What ingress protection rating does it have?
The device is rated IP20 when open and IP40 when installed inside a suitable enclosure, in accordance with IEC 60529.
What environmental conditions is it designed for?
It is specified for pollution degree 3 and relative humidity up to 95% at 55°C. Its plastic components are also identified as halogen-free.
Which standards and approvals apply?
The relay is listed as conforming to EN 669-1 and EN 669-2-2. Referenced marks and approvals include GOST, NF, VDE, CEBEC, KEMA, and IMQ.
What applications commonly use this impulse relay?
Typical applications include lighting circuits and other building-control loads that need to be toggled from multiple momentary push-button locations. The load type, voltage, current, operating frequency, and installation conditions should remain within the stated ratings.
