Product Description

The Siemens 3RT2015-2HB42 SIRIUS Overload Relay is engineered to provide advanced circuit protection for industrial electrical motors and automation equipment. Equipped with triple normally open (3 NO) contacts, this high-precision relay is ideal for safeguarding circuits from overload conditions and ensuring operational continuity in demanding applications such as process control, manufacturing, and automation panels.

Supporting a full load motor current of 6.1A and a robust contact current rating of 18A, this relay is capable of reliably switching and protecting single or three-phase electric motors up to 3 kW. Its 24V DC supply and control voltage compatibility make it suitable for integration into modern automated control systems. The SIRIUS series’ patented spring-loaded terminal design simplifies installation, guarantees solid wire connections, and reduces maintenance requirements.

Rated for 6.1A motor full load current, ideal for medium-duty motor circuits. 18A contact current capacity supports high-transient switch cycles. Capable of protecting motors and equipment up to 3 kW. Compatible with control panels using 24V DC supplies.

DIN rail mountable for efficient panel assembly and replacement. Includes 3 normally open (NO) auxiliary contacts for control circuit expansion or feedback. Spring terminal connection ensures secure and vibration-resistant wiring in industrial settings.

Rugged IP20 rated enclosure protects internal contacts and mechanisms against dust and accidental contact. Compact size (73mm wide, 45mm long, 69.5mm deep) allows high-density panel layouts. Wide operating temperature range from -25°C to 60°C handles both cold store and heated environments.

The relay meets UL, IEC 60947-5-1, IEC 60947-4-1, IEC 60529, EN 60947-1, and CSA standards, supporting global industrial requirements. Typical use cases include electrical machinery protection in automation, HVAC systems, CNC machinery, manufacturing lines, agricultural motors, and water treatment plants.

This Siemens SIRIUS overload relay is built for longevity, ease of integration, and reliable protection, making it an essential component for modern industrial control systems.
