STTCO modular terminal block component housing

The STTCO housings allow individual electronic components to be used in ST modular terminal block design. Up to five spring-cage connections that can be aligned as modules in a pitch of 6.2 mm are provided on two connection levels.


Designs with marking grooves, LED openings or knife disconnection, optional with PE contact to the DIN rail provide the required flexibility. The bridgability of the upper level has another advantage. A side cover for the housing is available.

The integrated base latch guarantees convenient and safe mounting on DIN rails as per EN 60715.
