3RT1015-1AP01
Siemens
The Siemens 3RT1015-1AP01 is a compact Size S00 power contactor from the SIRIUS 3RT1 series, designed for switching 3-phase motors and resistive loads. Rated for 9 A at AC-3 (400 V) and up to 4 kW motor power at 400 V, it features a 230 V AC 50/60 Hz coil and 1 built-in NO auxiliary contact. The screw terminal connections, IP20 finger-safe design, and 35 mm DIN rail mounting make it ideal for motor control panels, pump control, HVAC systems, and industrial automation applications. With a mechanical life of 10 million switching cycles and compliance with IEC 60947-4-1, this contactor delivers reliable performance in demanding environments.
FAQ
Q: What is the difference between 3RT1015-1AP01 and 3RT1025-1AP00?
A: The 3RT1015-1AP01 is Size S00 (9 A, 4 kW), while the 3RT1025-1AP00 is Size S0 (17 A, 7.5 kW). The S0 size has a larger frame and higher current rating for bigger motors.
Q: What coil voltage does the 3RT1015-1AP01 use?
A: It uses a 230 V AC coil operating at 50/60 Hz. The "1AP01" suffix indicates 230 V AC coil voltage in the Siemens naming convention.
Q: What motor power can this contactor switch at 400 V?
A: The 3RT1015-1AP01 can switch motors up to 4.0 kW at 400 V AC under AC-3 utilization category.
Q: Does this contactor come with auxiliary contacts?
A: Yes, it comes with 1 built-in NO (Normally Open) auxiliary contact. Additional auxiliary blocks can be snapped onto the side or front if more contacts are needed.
Q: What overload relay should be used with this contactor?
A: The standard matching overload relay for Size S00 is the 3RU11 21-4DB0 (manual auto-reset) or electronic overload relays from the 3RB series.
Q: Can this contactor be used for AC-4 duty (plugging/inching)?
A: Yes, but the rated current must be derated significantly — to approximately 3.3 A for AC-4 duty due to increased heat from frequent arcing.
Q: What are the dimensions of the 3RT1015-1AP01?
A: The dimensions are 57.5 mm (H) × 45 mm (W) × 73 mm (D), making it very compact and suitable for high-density panel layouts.
Q: How is the contactor mounted?
A: It can be mounted on a standard 35 mm DIN rail or via screw mounting using the provided mounting holes at the base.
