The Siemens 3VA2040-6JQ42-0AA0 is a SENTRON molded case circuit breaker rated for 40 A continuous at up to 70 °C ambient — no derating needed across the full operating range. Its 242 kA interrupting capacity at 240 V means it can clear a massive fault without upstream coordination issues; at 415 V that drops to 187 kA, still enough for most industrial service entrances.
