Product details

Panel fit and DIN-rail footprint

The 3RA6120-0EP30: The 45 mm width, 170 mm height, and 165 mm depth fit a standard DIN-rail slot — screw and snap-on mounting onto the rail, vertical orientation recommended.

Short-circuit and motor protection

Adjustable trip class CLASS 10 and 20 lets you match the overload release to the motor start profile — CLASS 10 for fast-starting pumps, CLASS 20 for high-inertia loads like conveyors. Rated motor power 15 kW at 400 V, with HP equivalents 7.5 hp at 200/208 V, 10 hp at 220/230 V, and 20 hp at 460/480 V.

Coil voltage and control wiring

AC/DC coil 110-240 V, 50/60 Hz — common industrial control voltage, works on both AC and DC supplies without a separate rectifier module.

Mechanical endurance for machine-mounted use

Shock rated 60 m/s² (6g) for 10 ms, three shocks per axis; vibration tested 4-5.8 Hz at 15 mm amplitude, 5.8-500 Hz at 20 m/s², 10 cycles — survives the vibration environment on a machine base or conveyor frame.

Frequently asked questions

What is the breaking capacity of the 3RA6120-0EP30 at 400 V?

53 kA at 400 V — this is the short-circuit breaking capacity for the motor branch circuit.

What is the trip class and is it adjustable?

Trip class is adjustable between CLASS 10 and CLASS 20. CLASS 10 suits low-inertia starts; CLASS 20 handles longer acceleration times.

What coil voltage does the 3RA6120-0EP30 accept?

AC/DC 110-240 V, 50/60 Hz — a single coil covers both AC and DC control supplies at common industrial voltages.
