The Siemens SENTRON 3VA2140-6HL46-0AA0 is a 4-pole molded case circuit breaker rated for 40 A continuous current across the full ambient range from 40 °C up to 70 °C — no derating needed within that span, which simplifies panel design in warm enclosures. Its ETU320 electronic trip unit provides adjustable N-conductor protection (OFF or 100 %), giving the panel builder control over how the neutral is handled in a 4-wire system. Breaking capacity is 242 kA at 240 V AC, dropping to 187 kA at 415 V and 440 V, then to 121 kA at 500 V, and 3.7 kA at 690 V — the 240 V figure tells you this breaker is built for high-fault utility or transformer-fed services where available short-circuit current is substantial.
