Product details

SIRIUS reversing starter in an IP65 enclosure

It carries a 0.75 kW rating at 400 V AC (2 A) and supports selectable trip classes 5, 10, 15, or 20, so you can match the overload protection curve to the motor start profile — fast trip for high-inertia loads, slower for soft-start applications. Supply is 24 V DC nominal (20.4 to 28.8 V range), with 4 digital inputs and 2 digital outputs for local control or connection to a higher-level automation system.

Dimensions are 294 mm wide by 215 mm high by 148 mm deep, with screw fixing and a recommended horizontal mounting orientation (vertical and flat also allowed). The IP65 enclosure means the starter can be mounted directly on a machine frame or wall without a separate panel — saves cabinet space but check that the 294 mm width fits your gland-plate or backplate layout. Environmental limits: operate from -25 to +55 °C, store/transport from -40 to +70 °C, with shock resistance of 12g / 11 ms and vibration resistance of 7 mm / 2g.

Frequently asked questions

What are the key ratings for this reversing starter?

Rated 0.75 kW at 400 V AC (2 A), with a 24 V DC control supply. It offers selectable trip classes 5, 10, 15, and 20, and has 4 digital inputs and 2 digital outputs.

What enclosure protection does this part have?

IP65 — dust-tight and protected against water jets, so it can be mounted directly in washdown or outdoor environments without a separate enclosure.

Will the 3RK1395-6KS41-3AD5 fit into a panel designed for a 3RT5065-6NF36?

The 3RK1395 is a reversing starter in an IP65 enclosure (294 x 215 x 148 mm), while the 3RT5065 is an open-frame contactor — different form factor. The power connection uses a HAN Q4/2 plug per ISO 23570, so verify the mating plug and mounting footprint before substituting.

What compliance documentation is available for this part?

The evidence does not list specific certificates (UL, CE, RoHS, etc.). Standard Siemens SIRIUS products are typically CE-marked and RoHS-compliant; request the declaration of conformity from your Siemens channel partner.
