3RT2038-1AP00
The Siemens SIRIUS 3RT2038-1AP00 is an S2-size three-pole power contactor with an AC-3 rated capacity of 80A and 37kW@400V. The operating coil is AC 230V 50Hz. It has one normally open and one normally closed auxiliary contact and screw terminal wiring. It is suitable for start-stop control of medium and large three-phase motors and power loads.
Product Positioning
The 3RT2038-1AP00 is a SIRIUS 3RT2 series S2 size contactor, positioned for direct starting and control of 37kW three-phase motors. It can be paired with the 3RV2 motor protection circuit breaker or overload relay to form a motor starter, and is commonly found in control panels of pumps, fans, compressors and conveying equipment.
Core Product Advantages and Features
AC-3 rated 80A
At 400V, the AC-3 has a rated current of 80A and a motor power of 37kW, while the AC-1 can handle a load of up to 90A at 40°C, which is sufficient to handle medium and large three-phase motor loads.
AC 230V operating coil
The operating coil is AC 230V 50Hz, with an operating range of 0.8 to 1.1 times the rated value, and can be directly connected to the single-phase 230V control power supply inside the panel.
Built-in 1 NO+1 NC contact
The main body has integrated 1 normally open and 1 normally closed instantaneous auxiliary contact, which can directly provide self-holding, interlocking or status feedback signals.
Mechanical life of 10 million cycles
With a typical mechanical life of 10 million cycles, the main circuit screw terminals can be connected to 1–50 mm² wires, making it suitable for long-term operation with frequent start-stop cycles.
