Product details

It is rated for a 110 VDC coil supply, with screw-type terminals for the magnet coil. The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and its mounting position allows +/-180° rotation on a vertical surface, plus +/-22.5° tilt forward and backward.

The 110 VDC coil draws a 15 A inrush peak, so the control transformer or DC supply must handle that surge without droop. The coil hold-in is rated for DC, with a drop-out time of 30 to 50 ms at DC — this matters for sequencing logic where you need predictable off-delay. Wire termination accepts solid conductors: 2x (1 to 2.5 mm²) and 2x (2.5 to 10 mm²) for the main contacts, and 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) for auxiliary circuits. This covers standard control wiring up to 10 mm² for power feeds.

This fits standard S0-size contactor spacing in most enclosures. Mechanical switching frequency: 1,000 operations per hour for AC-1, AC-2, AC-3, and AC-3e duty; 300 operations per hour for AC-4. The arcing time is 10 ms, consistent with DC coil contactors.

Frequently asked questions

What are the key dimensions for panel layout?

Width is 45 mm, depth is 107 mm, and height is 85 mm. Clearance required: 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm at the side.

What wire sizes does the contactor accept?

Main contacts accept solid conductors: 2x (1 to 2.5 mm²) and 2x (2.5 to 10 mm²). Auxiliary contacts accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded.

What is the coil voltage and type?

The coil is rated for 110 V DC, with screw-type terminals. Inrush peak is 15 A.
