The Siemens 3VA1116-3EF32-0AG0 is a 3-pole IEC frame 160 molded-case circuit breaker rated for line protection with a thermal-magnetic TM240 trip unit. Breaking capacity class N delivers Icu=25kA at 415 V AC — sufficient for most distribution panels and motor branch circuits in commercial and light industrial installations where fault levels stay under that threshold.
Key Ratings & Fit
Rated continuous current In=160 A with an adjustable overload protection band Ir=112 A…160 A, so the breaker can be dialed down to match a 125 A or 150 A load without swapping the frame. Short-circuit pickup Ii is adjustable 5…10 x In (800 A…1600 A), giving flexibility to coordinate with downstream branch breakers or motor starters. The TM240 thermal-magnetic trip provides instantaneous magnetic response for short-circuits plus a thermal delay for overloads — no electronic trip unit to power or configure.
Panel Integration
Mounts on a standard DIN rail or can be screw-fixed to a backplate. The nut keeper kit is included for secure terminal connections. An auxiliary switch HP and a trip alarm switch HP are factory-fitted, so the breaker reports its status (open/closed/tripped) back to a PLC or indication lamp without additional wiring of external contacts.
