What is this contactor used for?

It is a compact SIRIUS power contactor designed for switching three-phase AC loads, typically motor switching duties in AC-3/AC-3e applications. Typical motor rating is up to 4 kW at 400 V (AC-3).

What are the main switching ratings for motor duties?

For AC-3 motor switching, the operational current is 9 A at 400 V, with an operating power of 4 kW at 400 V. It is also commonly specified at 2.2 kW at 230 V and 5.5 kW at 690 V (AC-3).

How many poles and main contacts does it have?

It is a 3-pole contactor with 3 normally-open (NO) main power contacts for the main current circuit.

Does it have built-in auxiliary contacts?

Yes. It includes 1 normally-closed (NC) auxiliary contact as standard.

What is the coil control voltage and frequency?

The control coil is rated at 110 V AC, suitable for 50/60 Hz operation.

What coil voltage tolerance should be considered in operation?

The coil operating range factor is typically 0.8 to 1.1 of rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz, which helps accommodate normal supply variations.

What are the coil power consumption figures?

Typical apparent pick-up power is 27 VA at 50 Hz (about 24.3 VA at 60 Hz). Typical apparent holding power is 4.2 VA at 50 Hz (about 3.3 VA at 60 Hz).

What type of terminals does it use?

It uses screw-type terminals for the main current circuit, the auxiliary contacts, and the coil connections.

What cable sizes can be connected to the main terminals?

Typical connectable conductor cross-sections for the main contacts are 0.5 to 4 mm² (solid or stranded). Finely stranded conductors with core end processing are typically 0.5 to 2.5 mm².

What cable sizes can be connected to the auxiliary terminals?

Typical connectable conductor cross-sections for the auxiliary/control terminals are 0.5 to 4 mm² (solid or stranded), and 0.5 to 2.5 mm² for finely stranded conductors with core end processing.

How is it mounted in a control panel?

It can be screw-mounted or snapped onto a 35 mm DIN rail (DIN EN 60715). The device is designed for vertical mounting surfaces and allows a wide range of mounting orientations.

What are the overall dimensions?

Typical dimensions are 58 mm (H) x 45 mm (W) x 73 mm (D), making it suitable for compact panel layouts (contactor size S00).

What enclosure protection does it provide?

The front and terminal area are rated IP20, providing finger-safe protection from the front when installed correctly within a panel.

What environmental conditions is it designed for?

Typical operating ambient temperature range is -25 °C to +60 °C, with storage from -55 °C to +80 °C. Maximum installation altitude is typically 2,000 m above sea level.

What is the rated insulation and impulse withstand capability?

Typical rated insulation voltage is 690 V, and rated impulse withstand (surge) voltage is 6 kV for both main and auxiliary circuits.

How fast can it be switched in normal use?

Typical maximum operating frequency is up to 750 operations per hour for AC-3 duties. For no-load switching, it can be significantly higher (typically up to 10,000 operations per hour), depending on application conditions.

What are the auxiliary contact utilisation ratings?

The built-in NC auxiliary contact is commonly rated up to 10 A in AC-12. For AC-15, typical ratings include 10 A at 230 V and 3 A at 400 V. For DC-13, typical ratings include 1 A at 110 V and 0.3 A at 220 V.

What is typically used for short-circuit protection and coordination?

In many installations, gG fuses are used for short-circuit protection of the main circuit. Typical guidance includes 35 A (coordination type 1) and 20 A (coordination type 2), with an auxiliary circuit fuse typically around 10 A gG. Final selection must match the installation design and applicable standards.

Can it be used in a forward/reverse motor starter?

Yes, it can be used as a building block in a reversing arrangement, but reversing requires two contactors with appropriate electrical and mechanical interlocking to prevent simultaneous energisation.

Does it include a communication function module?

No. This contactor variant does not include a communication function module. If communication is required, it is typically implemented at the control level rather than within this device.

What does the built-in terminal marking refer to?

Typical terminal designations are 1/L1, 3/L2, 5/L3 for incoming supply and 2/T1, 4/T2, 6/T3 for outgoing load, with A1 and A2 for the coil, and 21/22 for the NC auxiliary contact.

Is this contactor suitable for switching resistive loads as well as motors?

Yes. In addition to motor duty (AC-3/AC-3e), it can switch resistive loads under AC-1 conditions, where the permissible current is typically higher than the AC-3 motor rating (for example, around 22 A at 400 V in AC-1 at 40 °C ambient).

What is the typical power dissipation to consider for panel heat calculations?

For panel thermal planning, typical power loss per pole can be low under rated motor duty (for example, around 0.7 W per conductor at AC-3, 400 V), but overall dissipation depends on load, duty cycle, and enclosure conditions.
