Actuators of the 300 series for fire protection and smoke extraction.

Product catalog summary

Introduction
The document introduces the 300 series actuators by Gruner, designed for fire protection and smoke extraction. These actuators are described as reliable, user-friendly, and flexible, benefiting from Gruner's extensive experience since 1954.

Specifications
The 300 series actuators are equipped with BLDC technology, ensuring up to 120,000 cycles for springs and motors. They are available for 24, 120, or 230 VAC/DC power supplies and are designed to reduce wear with fewer mechanical components.

Installation and Usability
The actuators are simple to mount due to consistent distances and feature a hinged connection for smoke detectors. They allow easy duct mounting and replacement of the thermal tripping device.

Quality Assurance
Advanced testing facilities and quality assurance strategies ensure high quality. Steel components provide safety, maintaining torque even at high temperatures. The actuators can operate reliably at ambient temperatures up to 80°C.

Performance and Efficiency
The actuators have passed tests at over 1000°C, ensuring safety. They feature a manual winding position indicator, thermoelectrical release, and spring prestressing for full torque across a 95° rotation angle. Options include position feedback, temperature protection, and more. They comply with CE and DIN EN standards.

Product Range
The 300 series covers a range of torques from 3 to 40 Nm, suitable for various applications. They offer options for temperature protection, smoke detector connectors, auxiliary switches, and Modbus RTU.

Company Overview
Gruner is known for flexibility and innovation in energy management, building management, drive technology, and automotive sectors. The company has a global presence with locations in Germany, Tunisia, Serbia, and India.
