Applications

APPLICATIONS

3RT5036-1AN20

Official product-specific information

Motor switching

Rated for AC-3 motor loads up to 22 kW at 400 V with a 50 A operational-current rating.

Industrial feeders

Suitable as the switching element in coordinated SIRIUS motor feeders and control panels.

Remote control

The 220 V AC, 50/60 Hz coil permits conventional control-circuit operation.

High mechanical duty

A mechanical endurance of 10 million cycles supports repeated industrial switching duty.

Construction

CONSTRUCTION

3RT5036-1AN20

Official product-specific information

Power poles

Three normally open main contacts provide the three-pole switching path.

Control system

The AC coil accepts 220 V at both 50 Hz and 60 Hz within the documented operating range.

Terminal system

Screw terminals are used for the main circuit and for control and auxiliary connections.

Protective design

The front is IP20 and finger-safe when installed as specified.

Installation

INSTALLATION

3RT5036-1AN20

Official product-specific information

Mounting options

Install by screw fixing or snap the contactor onto a 35 mm DIN rail in the permitted orientation.

Panel clearance

Allow for the 55 × 112 × 115 mm device envelope and access to all screw terminals.

Coil verification

Confirm a 220 V AC control supply and the correct 50/60 Hz operating range before wiring A1/A2.

Protection coordination

Select upstream short-circuit protection using the Siemens type 1 or type 2 coordination data for the application.

Compatibility

COMPATIBILITY

3RT5036-1AN20

Official product-specific information

SIRIUS system

Integrates with compatible Siemens SIRIUS overload relays and accessories selected for size S2 contactors.

Power circuit

Engineering must match the actual AC-3 current, motor voltage and power to the contactor ratings.

Control circuit

Replacement requires the exact 220 V AC coil code; a DC or different-voltage coil is not equivalent.

Environmental scope

Apply the specified -25 to +60 °C operating range and 2,000 m maximum installation altitude.

FAQ

3RT5036-1AN20

Product verification and procurement guidance

Q1. How can the quoted item be verified as the exact model?

Confirm 3RT5036-1AN20 on the Siemens nameplate and packaging. The key checks are size S2, three main poles, 220 V AC 50/60 Hz coil and screw terminals.

Q2. How can New, Used or Refurbished condition be distinguished?

Ask for dated photos of the label, terminal screws, arc-chute area, mounting surfaces and packaging. Used units may show screw marks, rail wear, heat discoloration or dust.

Q3. How can a supplier be checked before purchase?

Verify the legal company identity, registration, bank account and traceable quotation. The offer should state 3RT5036-1AN20, condition, quantity and inspection evidence.

Q4. Which specifications should engineering verify?

Check 50 A AC-3 at 400 V, 22 kW motor rating, 220 V AC coil, size S2, 55 × 112 × 115 mm envelope, terminal type and protection coordination.

Q5. What evidence should be requested before payment?

Request current photos of the complete nameplate, coil marking, all terminals, packaging seals and quantity together with a timestamp or order reference.

Q6. Can another 3RT50 suffix replace it?

Not without engineering review. The suffix defines coil voltage and terminal or equipment variants; a mechanically similar contactor may be electrically incompatible.
