If your enclosure runs hot, size the load side for the derated number — the breaker won't nuisance-trip on a warm day. Dimensions are 130 mm high, 50.8 mm wide, 70 mm deep — a compact 2-pole footprint that fits standard 50 mm wide MCCB slots.","metaTitle":"Siemens 3VA1112-5ED22-0AA0 SENTRON MCCB, 125 A, 2-Pole, TM21","metaDescription":"Siemens 3VA1112-5ED22-0AA0 SENTRON molded case circuit breaker, 125 A, 2-pole, TM210 release, 187 kA at 240 V AC.

The main difference is the overcurrent release type — the 5EE32 uses an electronic release instead of the TM210 thermal-magnetic.
