Aircraft; Procedure
While at cruise; FL250; noticed a burning smell; somewhat like an electrical fire. No smoke detected. Turned off recirculation fans and prepared to don O2 mask if necessary. Contacted Flight Attendant (FA) and asked her if she had noticed any kind of burning smell. She told us that she had not smelled anything. We continued on our course; when I noticed a stronger smell accompanied by a grinding and rumbling from Captain side of [the] aircraft. The First Officer noticed the smell as well. We [advised] ATC [which] had us go direct to ZZZ. Called back to the FA; and she stated that her and the passengers had heard the noise as well and that she had started to smell the burning/smoke. We continued as quickly and safely to ZZZ and landed. AARF met the aircraft once stopped on the runway and I had them check for any signs of damage. Once they gave the all clear we taxied to the gate deplaned; and Maintenance took the aircraft.Possible fire enroute. I probably could have slowed down a bit before analyzing the situation; and pulled out the QRH before jumping to conclusions.
EMB-145 Captain reported an electrical burning smell in flight; causing a diversion and precautionary landing.
