Siemens 3RT1 Series Contactor, 250V Coil Voltage, 200A Contact Current - 3RT1355-6AP36

This contactor is a four-pole switching device designed for safety-oriented AC applications and motor control. It accepts a 100…250V AC/DC control supply and provides high-current switching for resistive loads up to 75 kW at 400 V. The unit is engineered for ambient operation from -40°C to 60°C and supports vertical or flexible mounting positions with screw fixing and connection-bar terminations for the main circuit.

Features and Benefits:

• 200 A switching delivers high-current handling for heavy loads
• 250 V Coil nominal supports common AC control systems
• 75 kW at 400 V allows substantial motor power operation
• 2NO/2NC auxiliary contacts enable local control and signalling
• Screw terminals and connection bar ensure secure conductor termination

Applications

• Used for safety-related AC load switching in industrial panels
• Suitable for motor control up to 75 kW at 400 V
• Ideal for installations requiring AC/DC Coil flexibility
• Can be used where a wide ambient range is necessary
• Suitable for systems needing 2NO and 2NC auxiliary contacts

What is the operational current for AC-3 duty at 400 V?

It performs at 140 A for AC-3 at 400 V rated operation.

What short-circuit protection is specified for the main circuit?

Coordination type 2 requires a gG fuse of 250 A (500 V, 100 kA).

How are auxiliary and control connections made?

They use screw-type terminals suitable for 1…4 mm² conductors.
