Product details

The main circuit uses spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded wire, which speeds wiring and avoids the torque-check step of screw terminals.

The AC-2 rating of 4 kW at 400 V covers wound-rotor motor applications where starting current is moderate. The AC-4 rating of 8.5 A at 400 V handles plugging and inching duty — the tougher switching condition for contactor life. For DC switching, it's rated 10 A at 24 V and 0.3 A at 220 V, which covers small solenoid and brake loads. For type of coordination 2 (fault protection with limited damage), the required fuse is gL/gG 20 A. For type 1 coordination (immediate replacement after fault), it's gL/gG 35 A. This lets the panel designer match the upstream protection to the acceptable downtime.

The front face carries IP20 finger protection; the terminals are also IP20.

Frequently asked questions

What are the key ratings for this contactor?

AC-2 motor rating is 4 kW at 400 V. AC-4 rating is 8.5 A at 400 V. DC switching: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. Mechanical life is 30 million operations typical.

What wire sizes does the spring terminal accept?

The spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG). No special tools beyond a screwdriver for the spring release.

What is the closest functional alternative to this part?

The 3RT1016-2AP02 is a direct peer in the same S00 frame with identical mounting and terminal style. The main difference is the coil voltage — the -2AD01 uses a 24 V DC coil, while the -2AP02 uses a different coil voltage. Verify coil compatibility before substituting.

Will this drop into a panel wired for 3RT1016-2AP02?

Mechanically yes — same S00 frame, same 45 mm width, same DIN rail mounting. The spring terminals are identical. The only difference is the coil voltage; if the panel supplies 24 V DC, the -2AD01 is a direct swap without rewiring.
