Front IP40 protection means it's suited for enclosed distribution boards; no washdown rating, so keep it inside the cabinet. Power dissipation at full load is 17.3 W, which the panel cooling budget needs to absorb — not negligible in a densely packed enclosure. ## TM240 release and insulation coordination Rated insulation voltage is 800 V, and the storage temperature range runs from -40 °C to 80 °C, wider than the operating range (-25 °C to 70 °C). No undervoltage release, no shunt trip, no communication function on this variant — it's a plain line-protection MCCB.","metaTitle":"Siemens 3VA1163-4EF42-0AA0 SENTRON MCCB, 63 A, 4-pole, TM240","metaDescription":"Siemens 3VA1163-4EF42-0AA0 SENTRON molded case circuit breaker, 63 A rated at 40 °C, 4-pole, TM240 release, 121 kA at 240 V.
