The ETU860 is a programmable overcurrent release that supports LSIG protection (long-time, short-time, instantaneous, ground-fault) and includes a communication function for remote monitoring. The 3-pole design handles three-phase loads up to 800 V insulation voltage. Breaking capacity is the other headline: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V. Dimensions: 248 mm height, 138 mm width, 110 mm depth. No undervoltage release or voltage trigger is fitted on this variant.","metaTitle":"Siemens 3VA2463-7KQ32-0AA0 SENTRON MCCB, 630 A, 3-Pole, ETU8","metaDescription":"Siemens 3VA2463-7KQ32-0AA0 SENTRON molded case circuit breaker, 630 A at 40 °C, 3-pole, ETU860 trip unit.
