Frequently Asked Questions - 3RW4037-1BB15 SIEMENS

What is the rated current of the Siemens 3RW4037-1BB15?

The rated operational current (Ie) is 37 A at 400 V AC.

What is the control voltage for this soft starter?

The control supply voltage is 24 V DC.

Can I use the 3RW4037-1BB15 for both star-delta and direct-on-line starting?

No, this soft starter is designed for soft starting and stopping of three-phase motors, not for star-delta or DOL switching.

How do I reset the device after a fault?

Press the RESET button on the front panel or cycle the control supply voltage. For remote reset, use the digital input.

What is the ambient temperature range for operation?

The permissible ambient temperature is -25°C to +60°C.

Does the unit include a bypass contactor?

Yes, the 3RW4037-1BB15 has an integrated bypass for reducing heat dissipation during continuous operation.

Can I adjust the start ramp time?

Yes, the start ramp time can be set via the keypad or software from 0 to 20 seconds.

What protection features does it have?

It provides overload, short-circuit, phase failure, and overtemperature protection.

How do I clean the soft starter?

Disconnect power and clean with a dry, lint-free cloth. Do not use solvents.

What spare parts are available?

Common spare parts include the cooling fan and terminal clamps. Contact Siemens for replacements.
