The Siemens SENTRON 3VA1196-5EF42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 16 A at 40 °C and an interrupting capacity of 187 kA at 240 VAC — that figure drops to 121 kA at 415 V and 75.6 kA at 440 V, so the available fault current at the panel location governs which voltage class you size against.
Interrupting capacity and thermal-magnetic trip
The TM240 overcurrent release combines a thermal bimetal for overload protection with a magnetic coil for short-circuit response; the 240 designation indicates the magnetic trip threshold is fixed at 240 A (15× the 16 A frame rating).
The 16 A rating holds steady from 40 °C through 55 °C; at 60 °C it derates to 15 A, and at 70 °C it remains at 15 A — no further drop.
Dimensions are 130 mm high, 101.6 mm wide, 70 mm deep — a 4-pole frame that occupies roughly 4 inches of DIN width.
