The breaker also includes summation-current ground-fault monitoring, which sums the phase conductors to detect leakage without a separate GFCI module. The 105 mm width for a 3-pole 40 A breaker is compact for its class; it leaves room alongside for other SENTRON or SIRIUS components on the same rail. Power loss is only 1.2 W maximum, so heat buildup in a dense enclosure is minimal.","metaTitle":"Siemens 3VA2140-8HM36-0AA0 SENTRON MCCB, 40 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2140-8HM36-0AA0 molded case circuit breaker, 40 A continuous, 3-pole, 800 V insulation, 440 kA at 240 V.

The difference is in the internal trip unit and accessories — the 8HM36 variant is a line-protection breaker with ground-fault summation, while the 8JQ32 variant is a different configuration. If the panel wiring and protection scheme match the 8HM36's characteristics, it swaps in without rewiring."},{"question":"How do I get pricing and availability for the 3VA2140-8HM36-0AA0?","answer":"Submit an RFQ through the storefront.
