The Siemens 3VA1116-6GF42-0AA0 is a SENTRON 4-pole molded case circuit breaker (MCCB) rated at 160 A continuous, fitted with a TM240 thermal-magnetic overcurrent release. It is designed for line protection in distribution panels and switchboards where high fault current capacity is required. Breaking capacity is 220 kA at 240 V AC, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — these figures cover most industrial low-voltage networks and give solid selectivity headroom downstream. The 160 A rating holds at ambient temperatures up to 50 °C; above that it derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. If the panel runs hot — near a transformer or in a non-climate-controlled enclosure — check the actual load against the derated value rather than the nameplate 160 A.
Physical fit and integration
Dimensions are 70 mm deep, 101.6 mm wide, and 130 mm tall. The 4-pole body mounts on a DIN rail or directly to a backplate via the standard MCCB footprint. Front face carries IP40 protection — suitable for enclosed distribution boards where tools or fingers might contact the front but not for washdown environments. Rated insulation voltage is 800 V, and maximum power loss is 38 W at full load — factor that heat into enclosure sizing, especially in multi-breaker panels.
Key ratings at a glance
The TM240 thermal-magnetic release provides fixed thermal and magnetic trip settings suited for cable and busbar protection in line-protection applications. No undervoltage release, no trip indicator, no communication function, and no ground-fault monitoring are included on this variant. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
