Line-up and interrupting capacity
The Siemens SENTRON 3VA1196-4EF42-0AA0 is a 4-pole molded case circuit breaker (MCCB) designed for line protection, with a TM240 thermal-magnetic overcurrent release and a continuous current rating of 16 A across the 40 °C to 55 °C ambient band, derating to 15 A at 60 °C through 70 °C. Interrupting capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V — numbers that govern selectivity coordination in a main or feeder panel. The 70 mm depth, 101.6 mm width, and 130 mm height match the standard 3VA footprint, so a panel laid out for a 3VA1110 frame accepts this unit without busbar or mounting rework.
Installation and environmental limits
Rated insulation voltage 800 V, front-side IP40 protection — suitable for a dry indoor panel enclosure. Operating range -25 °C to +70 °C; storage from -40 °C to +80 °C. Maximum power loss 10.6 W — factor into enclosure thermal budget.
