Siemens 3RU2116-0JB0 Thermal Overload Relay

 
Alternative Views:
Siemens 3RU2116-0JB0 3 pole thermal overload relay that is adjustable from 0.70 to 1 AMP and mounts to any 3RT2015, 3RT2016, 3RT2017 or 3RT2018 3 pole contactor. This relay comes with 1 normally open and 1 normally closed base mounted auxiliary contacts, single phase sensitivity (trips when a phase loss is detected), screw terminals and has Class 10 tripping so it trips in 10 seconds or less in an over current situation.

Description Detailed Specifications
 
The 3RU2116 thermal overload relays up to 16A are designed for current-dependent protection of applications with normal start-up conditions against impermissibly high rises in temperature as a result of overload or phase failure. An overload or phase failure causes the motor current to rise above the set rated motor current. This current rise heats up the bimetal strips within the relay via heating elements which, in turn, operate the auxiliary contacts via a tripping mechanism due to their deflection. These switch the load off via a contactor. The switch-off time is dependent on the ratio of tripping current to operational current Ie and is stored in the form of a tripping characteristic with long-term stability. The "Tripped" state is signalled by means of a switching position indicator. Resetting takes place manually or automatically after a recovery time has elapsed.
