Description

Technical Specifications:

Rated Operational Current (Ie): 9 A at 400 V AC-3 / 16 A at 400 V AC-1
Rated Power (AC-3): 4 kW at 400 V (3-phase), 2.2 kW at 230 V (3-phase)
Coil Voltage: 24 V DC (wide range electronic coil design)
Pole Count: 3 NO (Normally Open) main contacts
Frame Size: 27 mm width (compact DIN design)
Rated Insulation Voltage (Ui): 690 V / 1000 V
Impulse Withstand Voltage (Uimp): 6 kV / 8 kV
Mechanical Life: >10 million operations
Electrical Life: >1 million operations (AC-3)
Standards: IEC 60947-4-1, UL 508, CSA C22.2, CCC, CE

Functional Characteristics: Reversing configuration (mechanical interlock ready), integrated suppressor circuit (for DC coil), silent hum-free operation, DIN rail or screw mount, snap-on auxiliary contact blocks.

Performance Parameters: Making Capacity: 10x Ie; Breaking Capacity: 8x Ie; Coil Power Consumption: < 5 W holding (electronic coil); Operating Time: 15–35 ms close / 10–25 ms open.

Material Composition: Contacts: Silver-cadmium oxide (AgCdO) or AgSnO₂ (cadmium-free); Arc Chute: Thermoset molding compound; Springs: Stainless steel; Housing: Self-extinguishing polyamide (PA6 GF25).

Structural Features: Front-access terminals (IP20 finger-safe), clear contact state indicator, modular side-by-side mounting, integrated labeling area, compact 45 mm width for 9A unit.

Working Principle: When 24 VDC is applied to the coil, an electronic circuit manages the current to create a magnetic flux in the iron core, attracting the moving armature against spring force, closing the main contacts and auxiliary contacts to complete the power circuit to the motor.

Advantages: Up to 80% lower holding energy vs traditional AC coils, wide voltage tolerance (prevents drop-out on sags), compact design saves panel space, global certification package for export machinery.

Applicable Industries: HVAC systems, Pump control panels, Conveyor drives, Crane & hoist controls, Machine tool power feeds, Renewable energy combiner boxes.

Model Series: Eaton Moeller (formerly xStart) series contactors.

Installation Requirements: Mount on 35 mm DIN rail EN 60715; torque terminals to 1.2 Nm (control) / 1.5 Nm (power); ensure phase barrier spacing; connect coil A1/A2 with correct polarity for DC; install surge suppression if switching inductive loads > 100 m.

Usage Precautions: Do not exceed 690 V between phases; verify AC-3 vs AC-1 rating for application; ensure reversing contactors have mechanical AND electrical interlock; de-energize before attaching auxiliary blocks; operating temperature -25°C to +55°C (derate if higher).
