HR3004SR Schneider HR3000 Guest Room 4 Way Heavy Duty Relay Module
High Power Circuit Switching Unit designed for loads that standard relay modules cannot handle in guest room control systems.
Product Overview
The HR3004SR heavy duty relay module is specifically engineered for high-power circuits in hotel guest rooms where standard relay modules are insufficient. This module handles significantly greater loads and more demanding switching duties required by equipment such as water heaters, heating systems, large fan coil units, and outdoor terrace circuits.
Operating on the 12V DC module bus and controlled by the main module, this unit distinguishes itself through enhanced capability rather than function, ensuring reliable performance for heavy-duty applications.

System Integration
Heavy duty switching separation from ordinary switching is essential for contact service life preservation. The engineering approach requires dividing controlled circuits into ordinary and heavy schedules before module selection, with clear documentation to prevent incorrect substitutions during maintenance.
Important Considerations: For intermittent heavy loads (such as heating), duty cycle evaluation is crucial alongside peak load assessment. Adequate ventilation within the enclosure is particularly important due to concentrated losses in high-current contacts.
Application Scenarios
Hotel Suites: Instantaneous water heaters, heated mirrors, underfloor heating circuits
Serviced Apartments: Domestic appliances within controlled circuit schedules
Cold Climate Properties: Bathroom and vestibule heating systems
Properties with Outdoor Areas: External terrace or balcony circuits controlled by room controller
This module ensures project integrity by requiring complete load schedule documentation before control panel construction, preventing underspecification in critical applications.
