Siemens 3RW52356TC15 Soft Starter — 600 V, 143 A, Chassis Mount

Catalog Comparison: 3RW52 Family (143 A, Soft Start/Stop)

The 3RW52356TC15 is a Siemens 3RW52 solid-state soft starter in the screw-terminal (TC) variant, rated 143 A output for a single AC motor. The table below compares catalog records sharing this output rating; all share the same soft-start function, AC motor type, chassis-mount form factor, and 25°C–60°C operating window.

All listed parts carry ROHS3 Compliant status, Active product lifecycle, and Box encapsulation.

Why the highest-similarity rows are catalog peers

• 3RW52356TC14 shares the TC suffix (screw terminals), identical 143 A output, 110–250 V control voltage, and 480 V load rating. The only listed difference is the lower load voltage class.
• 3RW52356TC05 shares the TC suffix, identical 600 V load rating, and identical 143 A output. The only listed difference is 24 V control voltage instead of 110–250 V.
• 3RW52356TC04 shares the TC suffix and 143 A output. The only listed differences are 480 V load voltage and 24 V control voltage.

These peers share the same soft-start/stop drive type, AC motor compatibility, and chassis-mounting form factor. The MPN suffix in the Siemens 3RW52 series encodes terminal style (TC = screw, AC = analog/screw) and voltage class; the reader's own qualification must confirm suitability for a specific motor rating and control architecture.

Soft-Start Integration Context

The 3RW52356TC15 operates as a standalone soft-start/stop controller for one AC motor. As a chassis-mount module, it is typically mounted within an enclosure or motor-control cabinet and wired into the motor branch. The 110–250 V control voltage range accommodates common control-circuit levels. All 3RW52 family members listed are single-motor units; no multi-motor expansion is reflected in the catalog records.

FAQ

What is the output current rating of the 3RW52356TC15? 143 A output, suitable for a single AC motor.

Does the 3RW52356TC15 support 480 V motor systems? The primary record specifies 600 V load voltage. For 480 V applications, the catalog lists 3RW52356TC14 as a same-family peer at 480 V load rating; the reader must verify coordination with the specific motor nameplate.

What control voltage does the 3RW52356TC15 require? 110–250 V control voltage. For 24 V control schemes, the catalog lists 3RW52356TC05 as a same-family peer with 24 V control input.
