The 400 V AC rated supply voltage (440 V max multi-phase) covers standard three-phase line-to-line feeds in European-style panels. Sealable with a lead seal (provision built in) for tamper-evident metering or critical circuits. Degree of pollution 2 and overvoltage category III are standard for fixed-installation distribution boards. ## Power loss and thermal consideration Each pole dissipates 3.1 W in hot operating state at rated current. For a 2-pole breaker that's 6.2 W total — negligible in a ventilated enclosure, but worth checking if the breaker is packed tight with other heat sources in a sealed box.","metaTitle":"Siemens 5SL3232-7 SENTRON MCB, 2P C 32A 400V 4.5kA","metaDescription":"Siemens 5SL3232-7 SENTRON miniature circuit breaker, 2-pole, C-curve, 32 A, 400 V AC, 4.5 kA per EN 60898.

The 5SL6220-7 has a higher breaking capacity (6 kA vs 4.5 kA EN 60898) and lower per-pole power loss (2.2 W vs 3.1 W), but the footprint and terminal layout are identical.
