Product details

Reversing starter for motor control panels — 15 kW at 400 V

The 3RA6250-1EB33: The adjustable trip class (CLASS 10 and 20) lets you match the overload protection to the motor start profile: CLASS 10 for faster-starting loads like pumps, CLASS 20 for high-inertia fans or conveyors that need a longer acceleration ramp.

Mounting and integration — DIN rail, any orientation

Snap-on or screw-fix to standard mounting rail in any position — vertical, horizontal, or flat — which gives panel builders flexibility in dense enclosures where rail orientation is constrained by other gear. The main current circuit uses a plug-in interface without terminals — the power connections are made via the matching SIRIUS bus system or direct plug-in links, not individual screw clamps.

Environmental ruggedness for machine-mount service

Rated for continuous operation per IEC 60947-6-2, with a pollution degree of 3 — suitable for industrial environments where conductive dust or humidity is present. Withstands shock at 60 m/s² (6 g) over 10 ms per three shocks in all axes, and vibration from 4 to 500 Hz at up to 20 m/s² — the unit holds up on machine-mounted panels near presses, conveyors, or compressors.

Frequently asked questions

What is the breaking capacity of the 3RA6250-1EB33?

53 kA at 400 V — this is the short-circuit current rating (SCCR) for fault coordination in motor control panels.

What trip class options does this reversing starter offer?

Adjustable between CLASS 10 and CLASS 20. CLASS 10 trips faster for standard motor starts; CLASS 20 allows longer acceleration for high-inertia loads like fans or centrifuges.
