Product details

The 10 A rating at 24 V is the contactor's rated operational current for its main contacts under AC-1 (resistive) or AC-3 (motor) duty at that coil voltage. For motor switching, the AC-3 maximum switching frequency is 750 cycles per hour, which suits conveyor and pump cycling without overheating the coil or contacts. The mechanical life of 30,000,000 operations indicates the contactor's endurance under no-load or light-load switching; actual electrical life will be lower and depends on the load current and switching category. The screw-type terminals on the magnet coil accept solid or stranded wire from 0.5 to 4 mm², with dual-wire capacity up to 2x 1.5 mm² solid or 2x 2.5 mm² stranded. This covers standard control wiring for 24 VDC circuits. The auxiliary switch is included, providing a normally open or closed feedback contact for PLC or status indication.

The contactor's dimensions are 58 mm high, 45 mm wide, and 73 mm deep. Vertical clearance above and below is 10 mm; forward clearance is also 10 mm.

Frequently asked questions

What are the key dimensions for panel layout?

The contactor measures 58 mm high, 45 mm wide, and 73 mm deep. Side clearance is 6 mm; vertical and forward clearance is 10 mm.

What wire sizes does the coil terminal accept?

The screw-type coil terminals accept solid or stranded wire from 0.5 to 4 mm², including dual-wire configurations up to 2x 1.5 mm² solid or 2x 2.5 mm² stranded.

What is the switching frequency for motor loads?

The maximum switching frequency under AC-3 duty (motor loads) is 750 cycles per hour.
