Breaking capacity is voltage-dependent: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. ## TM210 Overcurrent Release and Auxiliary Switch Configuration Fitted with a TM210 thermal-magnetic release — the '210' indicates the fixed thermal trip at 20 A and a magnetic short-circuit pickup that is adjustable or fixed per the TM210 variant. The basic switch variant is 3VA10203ED360AA0, and the auxiliary switch block carries three HQ auxiliary switches. The storage floor of -40 °C is typical for unheated warehouses in cold climates — the breaker can sit on a shelf through winter before installation.","metaTitle":"Siemens 3VA1020-3ED36-0AD0 SENTRON MCCB, 20 A, 3-Pole, TM210","metaDescription":"Siemens 3VA1020-3ED36-0AD0 SENTRON molded case circuit breaker, 20 A rated at 40-55 °C, 3-pole, 75.6 kA at 240 V.
