That means in a warm panel — say 55 °C internal ambient — you lose 1 A of headroom per pole. The 32 A rating is the starting point; the thermal curve governs the real-world limit. ## Interrupting capacity across voltages Breaking capacity is voltage-dependent: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a 480 V distribution panel (common in North American industrial), the relevant figure is the 440 V rating at 32 kA — that is the closest published point. The 690 V rating at 11.9 kA covers European 400/690 V systems. ## Auxiliary and release configuration This variant ships with two auxiliary switches (HQ type) and an undervoltage release (UVR). The auxiliary switches provide status feedback — open/closed indication — for PLC or SCADA monitoring. No communication function or ground-fault monitoring on this order code. Width at 76.2 mm (3 inches) is standard for a 3-pole MCCB in this class; it occupies three 25.4 mm module positions on a DIN rail if the mounting adapter is used.","metaTitle":"Siemens 3VA1132-3EF36-0BC0 SENTRON MCCB, 32 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1132-3EF36-0BC0 molded case circuit breaker. 32 A rated at 40 °C, 3-pole, 75.6 kA interrupting at 240 V.
