Siemens 3RT2015-1AP04-3MA0 Power Contactor, 3-Pole, 7A, 230V AC Coil, 2NO+2NC Auxiliary Contacts, Size S00

The Siemens 3RT2015-1AP04-3MA0 is a high-performance 3-pole power contactor engineered for demanding industrial switching tasks. Designed for reliability and longevity, this size S00 contactor provides a rated operational current of 7A and operates with a 230V AC control coil. It is equipped with a versatile configuration of 2 normally open (NO) and 2 normally closed (NC) auxiliary contacts, making it a robust solution for managing motors and complex electrical control systems in professional environments.

Advantages

This power contactor stands out due to its compact S00 frame size, which allows for space-efficient mounting within crowded control cabinets. The device is built to withstand rigorous industrial conditions, ensuring consistent performance and high operational reliability. With its integrated auxiliary contacts, it offers enhanced flexibility for feedback and interlocking circuits, reducing the need for additional components and simplifying the overall design of electrical control panels.

Suitable for

• Motor control and protection systems
• Industrial automation and control panels
• Switching resistive and inductive loads
• HVAC system control
• Lighting control circuits

When it may not be suitable

This contactor is not intended for high-voltage power distribution applications exceeding its rated operational current or voltage specifications. It is also not suitable for environments requiring specialized explosion-proof enclosures unless installed within an appropriate certified housing.

Key specifications

• Number of poles: 3
• Rated operational current: 7A
• Control coil voltage: 230V AC
• Auxiliary contact configuration: 2NO + 2NC
• Size: S00

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The contactor is designed for mounting on standard DIN rails or via screw mounting within an electrical enclosure. Connect the main power lines to the primary terminals and the control circuit to the coil terminals. Ensure that the auxiliary contacts are wired correctly to your control logic to facilitate proper feedback or interlocking functions. Always verify that the supply voltage matches the coil rating before energizing the device.

What to consider before purchase

• Verify that the 230V AC control voltage matches your existing control system.
• Ensure the 7A current rating is sufficient for your specific motor or load requirements.
• Check available space in your control cabinet to accommodate the S00 size.
• Confirm that the 2NO+2NC auxiliary contact configuration meets your circuit design needs.

Usage recommendations

Regularly inspect the terminal connections for tightness and check for signs of wear or debris accumulation to maintain optimal electrical conductivity and long-term operational safety.
