Thermal Circuit Breaker 3120-F...  
Description  
The 3120 circuit breaker/switch combination is an ON/OFF switch  
with integral overcurrent protection (S-type TO CBE to EN/IEC  
60934). The trip element is a bimetal. Type 3120 is ideally suited for  
overload protection of motors, pumps, transformers and cables.  
Product characteristics:  
l rocker or push button actuation  
l single pole and double pole versions  
l reliable switching behaviour (positively trip-free)  
l convenient snap-in mounting  
l international approvals  
1
Options and add-on modules:  
l illumination  
l water splash protection  
l auxiliary contacts  
l under voltage trip  
l remote trip  
Technical data  
l magnetic trip (see thermal-magnetic circuit breakers)  
l push-in terminals  
For details please see Technical information  
l appliance inlet module
