If your panel ambient runs at 60 °C, you lose 5 A — plan your load accordingly. ## Auxiliary and release configuration The two auxiliary switches provide status feedback (open/closed) to a PLC or indication lamp. No ground-fault monitoring or communication function on this variant.","metaTitle":"Siemens 3VA1112-5ED32-0BC0 SENTRON MCCB, 125 A, 3-Pole, 187","metaDescription":"Siemens 3VA1112-5ED32-0BC0 SENTRON molded case circuit breaker, 125 A rated at 40 °C, 3-pole, 187 kA breaking capacity at 240 V.
