That simplifies panel design — the breaker delivers its full ampacity across the typical industrial ambient span. No undervoltage release or communication module is fitted on this variant.","metaTitle":"Siemens 3VA2025-8HM32-0AA0 SENTRON MCCB, 25 A, 3-Pole, ETU33","metaDescription":"Siemens SENTRON 3VA2025-8HM32-0AA0 molded case circuit breaker, 25 A, 3-pole, ETU330 electronic trip, interrupting 440 kA at 240 VAC.
