Siemens 3RT2027-2AP04 SIRIUS 3RT2 Contactor, 32A, 15kW, 230V AC, Spring-Loaded Original Brand New

Overview: Siemens 3RT2027-2AP04 SIRIUS 3RT2 Power Contactor

The Siemens 3RT2027-2AP04 is a high-performance, 3-pole Power Contactor from the renowned SIRIUS 3RT2 series, designed for efficient and reliable motor switching applications. Featuring a compact Size S0 design, this contactor is built for robustness and high contact reliability, making it a cornerstone for industrial control systems and load feeders.

It is rated for a maximum operational current of 32 A (AC-3e/AC-3) and a power rating of 15 kW at 400 V. The control circuit operates with a 230 V AC, 50 Hz coil voltage. A key feature is the quick and vibration-proof spring-loaded terminal connection technology for both main and auxiliary circuits, ensuring minimal wiring effort and maintenance. It comes pre-fitted with a removable auxiliary switch block of 2 NO + 2 NC contacts.

Benefits & Features

• Optimal Performance: Rated for 32 A and 15 kW, providing robust power switching capabilities for medium-sized motors.
• SIRIUS Modular System: Part of the highly coordinated SIRIUS range, ensuring easy integration with other control components like overload relays (e.g., 3RU2), circuit breakers, and function modules.
• Fast & Reliable Wiring: Spring-loaded terminal technology offers a quick, secure, maintenance-free, and highly vibration-resistant connection, significantly reducing installation time compared to screw terminals.
• Enhanced Diagnostics: Integrated 2 NO + 2 NC auxiliary contacts simplify control circuit feedback and interlocking.
• Global Application: Climate-resistant and globally approved (IEC and UL/CSA), making it suitable for international use.
• Space-Saving Design: Compact Size S0 minimizes panel space requirements.
• AC-3e/AC-3 Rating: Complies with the latest standards for motor switching.

Function/Application

The Siemens 3RT2027-2AP04 contactor is primarily used as a switching device in industrial applications for:

1. Motor Switching: Direct-On-Line (DOL) starting and stopping of 3-phase AC motors (up to 15 kW).
2. General Resistive Loads: Switching of lighting, heating, and other general AC loads.
3. Use in Load Feeders: Forming part of a protective and switching assembly in combination with motor protection circuit breakers (MPCBs) and overload relays.
