Siemens Soft Starter 3RW3046-1BB04

The Siemens Soft Starter 3RW3046-1BB04 is a SIRIUS size S3 basic performance soft starter designed to reduce motor voltage during startup through variable phase control, limiting torque and inrush current to prevent mechanical shocks.

Specification:

• Product Type: SIRIUS 3RW30 soft starter.
• Size: S3.
• Current Rating: 80 A (at 40 °C ambient temperature).
• Motor Power Rating: 45 kW (at 400 V AC and 40 °C).
• Operating Voltage: 200-480 V AC.
• Control Voltage: 24 V AC/DC.
• Terminals: Screw terminals.

Features:

• Compact Design: The integrated bypass contacts significantly reduce heat dissipation after startup, allowing for a compact design without the need for complex external bypass circuits.
• Flexible Starting Voltage: Unlike wye-delta starters, the 3RW3046-1BB04 allows for a selectable starting voltage value, which can be individually adjusted to meet specific application requirements.
