Models SB315 B with thermal contacts wired to the terminal block andmust be connected to a motor
protection unit (Accessory: MW,
Ref. No. 1579). Models SB 315 C with thermalcontacts wired in series with the
windings. After responding resetby switching mains supply offand on. Sound levels In-line air filter box Total sound power levels and the spectrum figuresin dB(A) are given for case breakout
intake and exhaustin the tables above the performance curves.In addition the case breakout figure is given as a sound pressure level at 1 metre (freefield conditions) in the technical data table (see facing page).Note: For silentbox the sound level on intake is lower than on
exhaust. LFBR 315 Ref. No. 8581Air filter with big cross sectionalarea to be installed in-line with
