Interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 500 V, and 52.5 kA at 690 V, giving selectivity headroom for high-fault utility feeds or transformer secondaries. ## Key Ratings & Fit The TM240 release means the thermal pickup is fixed at 1000 A (the breaker frame rating), with magnetic trip set at 2400 A (2.4× In). That magnetic threshold suits motor-starting inrush or transformer energization where a lower magnetic setting would nuisance-trip. The undervoltage release drops the breaker when control voltage falls below a threshold — specify the coil voltage separately; it is not included in this order code. Dimensions: 320 mm height, 210 mm width, 120 mm depth. The 3-pole footprint is standard for SENTRON 3VA frame sizes in this rating class. Mounts via the rear panel or a DIN-rail adapter (not included). The undervolture release wiring terminates at the breaker's auxiliary terminal block — confirm polarity and voltage rating against the coil spec before panel wiring.","metaTitle":"Siemens 3VA1510-5EF32-0DA0 SENTRON MCCB, 1000 A, 3-Pole, 187","metaDescription":"Siemens SENTRON molded case circuit breaker, 3VA1510-5EF32-0DA0.
