Quick Summary

Eaton RoundTech MSSO surface emergency luminaire provides reliable escape-route lighting for indoor facilities. Maintenance-heavy emergency lights and poor battery life are common pain points that drive up downtime and cost. This model features CE certification, IP44 protection, and a 3-hour autonomy, delivering safety compliance under varied ambient conditions. With its ceiling surface mounting, plug-in connection, and long-life Li‑ion battery, it offers fast installation and predictable performance for retrofits and new builds. Designed for 5 °C to 45 °C environments, the 150-lumen output provides clear illumination in corridors, open areas, and stairwells, supporting occupation safety and regulatory adherence. The device's non-maintained operation and energy-efficient performance also help facility managers meet ongoing safety audits with minimal intervention. In practice, it reduces energy waste, extends battery life, and accelerates commissioning for new builds.

Feature → Business Impact → Application: Compact surface-mount design enables rapid installation on existing ceilings, reducing labor time and operational disruption during retrofits or new projects. This translates to lower total installed cost and faster project handover in manufacturing floors and office interiors. Application: ceiling surface mounting with plug-in connection for quick wiring and simplified maintenance. Feature → Business Impact → Application: 150 lm output with 5700 K white light and focal lens provides a crisp, uniform escape-route illumination that improves visibility in corridors and stairwells, supporting safe egress during emergencies. Application: indoor open areas and egress corridors in warehouses and facilities. Feature → Business Impact → Application: Li‑ion battery (3.2 V) with peripheral (individual) power supply delivers reliable autonomy up to 3 hours with long cycle life, reducing replacement frequency and maintenance costs. Application: prolonged outages or intermittent power events in factories and large offices. Feature → Business Impact → Application: IP44 protection, IK04 impact resistance, and enclosure materials (plastic housing, transparent cover) ensure durability in light-industrial environments, minimizing failures due to dust, humidity, or incidental impacts. Application: indoor production floors, mezzanines, and loading areas. Feature → Business Impact → Application: Energy efficiency metrics (0.2 W max, PF ~0.45) lower standby and running consumption, contributing to ongoing energy savings and sustainability reporting. Application: energy-conscious facilities and green-building initiatives. Feature → Business Impact → Application: 230 V AC nominal input with 50/60 Hz compatibility and plug-in connection streamline integration with existing electrical infrastructure, reducing commissioning time and risk during startup. Application: retrofit into older installations or new-builds with standard mains supply.

FAQs

This luminaire is designed for ceiling surface mounting with a plug-in connection to a 230 V AC supply. It uses a 2.5 mm² conductor size and a peripheral battery configuration, enabling rapid wiring and straightforward retrofits. The NM mode ensures it remains inactive until an emergency condition is detected, simplifying ongoing maintenance.
The RT2SSO150SA3HC delivers 150 lumens of white light with a color temperature of 5700 K. The focal lens provides a clear, high-contrast illumination suitable for escape routes and open-area lighting in indoor settings.
Yes. The unit is rated for indoor use with IP44 protection, which provides adequate dust and splash protection for typical indoor corridors and open areas. It is not certified for outdoor or fully exposed damp environments, so installation should be in dry, indoor spaces.
Key certifications include CE marking for compliance with EU regulations and an IP44 ingress protection rating. It offers a 3-hour emergency operation and 60600-hour rated life under standard conditions, with a thermally safe, non-maintained operation suitable for compliance audits in commercial and light-industrial facilities.
The LED source is non-exchangeable, with a long service life of approximately 60,600 hours L70/B10 at 25 °C, reducing lamp-replacement frequency. A Li‑ion battery and efficient standby power minimize energy use (0.2 W max), lowering operating costs and contributing to faster ROI through reduced maintenance and more reliable emergency lighting.
