Maximum power loss is 40.5 W — factor that into your enclosure's thermal budget if you're stacking multiple breakers in a sealed panel. ## Panel fit and mechanicals The 70 mm depth leaves clearance for rear-access wiring and gland plates. The breaker includes two HQ auxiliary switches (form C) and an undervoltage release (UVR). The storage ceiling is higher than the operating ceiling — that's typical for shipping and warehouse conditions. No ground-fault monitoring version is included; if you need GF protection, you'd add an external module or choose a different variant.","metaTitle":"Siemens 3VA1116-5ED42-0BC0 SENTRON MCCB, 160A, 4-Pole, 187kA","metaDescription":"Siemens 3VA1116-5ED42-0BC0 SENTRON molded case circuit breaker, 160A rated, 4-pole, 187kA interrupting at 240V.
