3RF2030-1AA04

What type of component is this?

It is a single-phase solid-state semiconductor relay from the SIRIUS 3RF2 range, designed for switching AC loads using a DC control signal. It uses zero-point switching, making it suitable for frequent switching of resistive loads.

What load voltage range can it switch?

The main AC circuit is rated for 48 to 460 V at 50 or 60 Hz. Its operating range extends from 40 to 506 V AC, depending on frequency.

What is the rated load current?

The relay is rated for 30 A, including AC-51 applications and UL 508-rated operation. The minimum operating current is 500 mA.

What control voltage does it require?

The control input is DC. It is rated at 30 V DC and operates across a 15 to 24 V DC control supply range, with a typical rated control current of 15 mA.

Does it use zero-cross switching?

Yes. The relay has a zero-point switching function, meaning it switches close to the AC waveform zero crossing to reduce electrical stress and interference when controlling suitable loads.

What are the physical dimensions?

The unit measures 58 mm high, 45 mm wide and 48 mm deep. Its 45 mm width makes it a compact single-phase relay for panel mounting.

How is it mounted?

It is designed for screw fixing and can be mounted side by side with compatible devices. The maximum tightening torque for the fixing screw is 1.5 N·m.

What type of terminals does it have?

The relay uses screw-type terminals for both the main current circuit and the auxiliary/control circuit. Main contacts use M4 screws, while auxiliary and control contacts use M3 screws.

What conductor sizes can be connected to the main terminals?

For the main contacts, solid conductors from 1.5 to 6 mm² can be used. Finely stranded conductors with core end processing can be used from 1 to 10 mm², depending on the connection arrangement.

What tightening torque should be used for the terminals?

The main contact screw terminals require 2 to 2.5 N·m. The auxiliary and control terminals require 0.5 to 0.6 N·m.

What are the wire stripping lengths?

The recommended stripping length is 10 mm for the main contacts and 7 mm for the auxiliary and control contacts.

What ambient temperature range is it rated for?

The relay is rated for operation from -25 °C to +60 °C and storage from -55 °C to +80 °C. Derating begins at 40 °C.

What is the ingress protection rating?

The front of the device is rated IP20 according to IEC 60529. It is finger-safe for vertical contact from the front.

What is the rated insulation voltage?

The rated insulation voltage is 600 V, making the relay suitable for many industrial AC switching applications within its rated limits.

What is the power loss at rated current?

At rated AC current in a hot operating state, the power loss is 44.2 W. This should be considered when designing enclosure ventilation and heat dissipation.

What short-circuit protection options are specified?

Specified protective fuse options include Siemens fuse references such as 3NE1815-0, 5SE1325, 3NE8003-1, 3NC1025, 3NC1430, 3NC2232, 3NA6803, 3NW6101-1, 5SB251 and 5SE2313-2A, depending on fuse style and protection category.

What is the surge current rating?

The relay has a rated surge current resistance of 300 A and a maximum I²t value of 450 A²s.

What are the switching delay times?

The ON-delay time is 1 ms plus a maximum of one half-wave. The OFF-delay time is also 1 ms plus a maximum of one half-wave.

What applications is it commonly used for?

This type of relay is commonly used for frequent switching of single-phase AC loads such as heaters, resistive loads, industrial process equipment and control cabinet applications where silent, wear-free switching is useful.

Does it include auxiliary contacts?

No. This relay has no normally open, normally closed or changeover auxiliary contacts. It is a single-pole main switching device with a DC control input.
