Siemens SIRIUS 3RU2 Series Thermal Overload Relay, 1.6A Operational current, 1.1 to 1.6A Adjustable Current Range - 3RU2116-1AB1
This thermal overload relay provides motor protection by sensing phase currents and isolating motors when overload conditions occur. Designed for stand-alone installation, it operates across 50 to 60 Hz systems with a rated control voltage of 690 V and delivers thermal tripping for three-phase circuits. The device incorporates an integrated auxiliary switch for signalling and supports both automatic and manual reset modes to suit varied control strategies.
Features and Benefits:
• 1.6 A operational current assures protection for low-power motors
• 1.1 to 1.6 A adjustable current allows precise motor matching
• 3 poles provide three-phase overload detection for balanced protection
• Class10 trip behaviour limits thermal stress during short overloads
• Screw terminals enable secure electrical connections under vibration
• 1.1 to 1.6 A adjustable current allows precise motor matching
• 3 poles provide three-phase overload detection for balanced protection
• Class10 trip behaviour limits thermal stress during short overloads
• Screw terminals enable secure electrical connections under vibration
Applications
• Suitable for protecting small three-phase motors on conveyors
• Used with contactors for starter assemblies in machinery panels
• Ideal for workshop motor starters requiring adjustable settings
• Can be used for retrofit motor protection in Compact installations
• Used with contactors for starter assemblies in machinery panels
• Ideal for workshop motor starters requiring adjustable settings
• Can be used for retrofit motor protection in Compact installations
What ambient temperature range can it tolerate during operation?
It operates between -40 °C and +70 °C for normal use.
How is the device mounted and oriented?
It is intended for stand-alone installation on a vertical plane with limited rotation and tilt as specified in the manual.
What auxiliary contact functions are provided for control circuits?
One normally open contact is available for trip signalling and one normally closed contact for contactor disconnection.
What short-term electrical stresses can the relay withstand?
It has a rated surge voltage resistance of 6 kV and is designed for an insulation voltage up to 690 V.
What conductor types and sizes are supported by the main terminals?
Main contacts accept solid, stranded, or finely stranded conductors up to 4 mm² and equivalent AWG sizes as specified.
