3RT2015-1AN61

What is this component used for in an electrical control panel?

It is a 3-pole power contactor used to switch and control three-phase loads such as motors. This particular unit is typically applied for motor switching duties up to 3 kW at 400 V under AC-3/AC-3e conditions (e.g., Siemens 3RT2015-1AN61).

How many main poles and main contacts does it have?

It has 3 main poles with 3 normally-open (NO) main contacts, designed for switching the main current circuit.

What are the typical motor switching ratings (AC-3 / AC-3e)?

Typical operational current is 7 A at 400 V (AC-3/AC-3e). Typical motor power is 3 kW at 400 V, and up to 4 kW at 690 V (AC-3/AC-3e).

What is the maximum operating voltage for the main circuit?

The main circuit is rated up to 690 V for AC-3 and AC-3e applications.

What control coil voltage does it require?

The coil is rated for AC control supply: 200 V AC at 50 Hz, and 200–220 V AC at 60 Hz.

What is the acceptable operating range for the coil supply?

For 50 Hz operation, the coil operating range factor is 0.8 to 1.1 of rated voltage; for 60 Hz operation, it is 0.85 to 1.1 of rated voltage.

What are the coil power consumption figures?

Typical apparent pick-up power is 26.4 VA (50 Hz) or 31.7 VA (60 Hz). Typical apparent holding power is 4.4 VA (50 Hz) or 4.8 VA (60 Hz).

Does it include auxiliary contacts, and what are they?

Yes. It includes 1 instantaneous normally-open (NO) auxiliary contact.

What are the auxiliary contact electrical ratings?

Typical ratings include: AC-15: 10 A at 230 V, 3 A at 400 V, 2 A at 500 V, 1 A at 690 V. DC-13: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.15 A at 600 V.

What are the physical dimensions of the device?

Typical overall dimensions are 58 mm (H) × 45 mm (W) × 73 mm (D).

How is it mounted inside a panel?

It supports screw mounting and snap-on mounting onto a 35 mm DIN rail (DIN EN 60715). Side-by-side mounting is permitted.

What mounting orientation is allowed?

It can be rotated ±180° on a vertical mounting surface, and it can be tilted forward/back by ±22.5° on a vertical mounting surface.

What terminal type does it use, and what cable sizes can be connected?

It uses screw-type terminals for main, auxiliary, and coil connections. Typical connectable conductor cross-sections are 0.5 to 4 mm² for solid/stranded on main and auxiliary terminals (finely stranded with ferrules typically up to 2.5 mm²). AWG range is typically 20 to 12.

What is the operating temperature range?

Typical ambient temperature range during operation is -25 °C to +60 °C. Typical storage temperature range is -55 °C to +80 °C.

What is the front ingress protection rating?

The front is rated IP20, with finger-safe touch protection from the front (per IEC 60529).

What switching frequency can it handle?

Typical maximum no-load switching frequency is up to 10,000 operations per hour. Under AC-3/AC-3e duties, typical maximum is 750 operations per hour.

What is the expected mechanical service life?

Typical mechanical service life of the contactor is about 30,000,000 operating cycles.

What should be considered for short-circuit protection selection?

Short-circuit protection depends on the coordination type and the circuit. For the main circuit, typical fuse recommendations include gG 35 A (coordination type 1) or gG 20 A (coordination type 2) at up to 690 V (with high breaking capacities). For the auxiliary circuit up to 230 V, a typical recommendation is a C-curve miniature circuit breaker at 10 A with 0.4 kA breaking capacity.
