Product Overview
Compact 45 mm frame miniature switching device engineered for motor control and general automation loads. It features three normally open main power poles, an integrated normally closed auxiliary contact, and a DC coil circuit equipped with built-in surge suppression across terminals A1+ and A2-. Rated for up to 20 A thermal current (AC-1) and 4 kW at 400 V (AC-3), this unit mounts directly to standard 35 mm DIN rail or panel surfaces using M4 hardware.
Key Features
- Pole configuration: 3PST-NO main contacts plus 1 NC auxiliary contact (terminals 21-22)
- Coil operation: DC coil with integrated diode and resistor surge suppression
- AC-1 rating: Ie = Ith 20 A open, Uimp 6000 V
- AC-3 motor switching capacity: 2.2 kW at 220-240 V, 4.0 kW at 380-440 V, 4.0 kW at 500 V, 4.0 kW at 660-690 V
- UL/CSA ratings: 3-phase 5 HP at 460 V / 575 V, 3 HP at 230 V; 15 A open maximum at 600 V AC
- Auxiliary pilot duty rating: A600, P300
- Mounting format: 35 mm DIN rail or panel mount (35 x 50 mm hole pattern for M4 screws)
- Terminals: Screw clamp terminals accepting 18 to 14 AWG copper wire
Applications
- Replacing a failed mini contactor in legacy European machinery panels and machine tools
- Controlling 3-phase pump, fan, or conveyor motors up to 5 HP in automated work cells
- Switching dedicated workshop tools, compressors, and dust collectors with 24 V DC safety control circuits
- Integrating interlocked motor reverse or starter circuits using the built-in NC auxiliary contact
Frequently Asked Questions
What coil voltage does this contactor require?
The unit features a DC-operated coil with integrated polarity-marked suppression terminals (A1+ and A2-), standard for 24 V DC control circuits in the DILEM series.
Can this contactor be mounted to standard DIN rail?
Yes. The back chassis snaps onto standard 35 mm DIN rail and also includes slotted mounting holes spaced 35 x 50 mm for M4 panel-mount screws.
What is the purpose of the 21-22 NC contact?
Terminals 21 and 22 are a normally closed auxiliary contact, commonly wired into electrical interlocks, status indicators, or reversing contactor pairs to prevent simultaneous energization.
What Eaton part numbers correspond to this model?
Modern Eaton Moeller cross-references include DILEM-01-G, article number 010343, and North American catalog designation XTMC9A01TD.
Built for dense industrial control cabinets where space is tight and reliability cannot be compromised. Swap it into your panel and put the machine back to work.
