Description
Single or two pole rocker switch/thermal-magnetic circuit breaker (S-
type TM CBE to EN 60934). The addition of a magnetic tripping module
to the type 3120 range described in catalogue section 1 extends the
choices available to include single pole with thermal-magnetic
protection; double pole switching with thermal-magnetic protection on
one pole, thermal protection on the other; double pole switching with
thermal-magnetic protection on one pole only. All are offered with
rocker switch or push button control - two buttons for ON/OFF or one
button press-to-reset only, in designs to suit one of three different panel
cut-out sizes. Neon illumination (filament bulb for low voltages) is
optional. Approved to CBE standard EN 60934 (IEC 934).
