Siemens SENTRON 3VA1032-4ED36-0AA0 — 32 A MCCB, line protection
Its TM210 overcurrent release provides fixed thermal-magnetic protection — thermal for overloads, magnetic for short-circuits — with no undervoltage release or trip indicator fitted on this variant. Breaking capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V, giving ample SCCR headroom for most low-voltage distribution applications. Rated insulation voltage is 800 V, and the breaker maintains full 32 A rating up to 50 °C ambient; derating begins at 55 °C (31 A) and reaches 30 A at 70 °C.
Panel fit and thermal management
The breaker occupies 76.2 mm width, 130 mm height, and 70 mm depth — a standard 3-pole MCCB footprint that drops into most DIN-rail or panel-mount enclosures without re-drilling. Maximum power loss is 10.6 W.
No communication function, ground-fault monitoring, or voltage-trigger features are built in — this is a straight line-protection MCCB with no auxiliary electronics.
