| Description | Magnetic-Hydraulic Breaker; 20 A; 3-Pole; AA (AC, General Purpose) |
| Datasheet | Download Datasheet |
The IDEC NRBM3100-20A-AA is a 3-pole 20 A magnetic-hydraulic circuit protector with a lever actuator, rated 250V AC, 50/60 Hz and 65V DC. It is a UL 1077 supplementary protector, not for branch circuit protection.
It has IDEC's AA time-delay curve, the general-purpose curve common to molded-case breakers. All poles trip together and the levers are mechanically tied. The trip current does not drift with temperature; only the delay does.
Trip times at 25 °C: No trip at 100%; 15-120 s at 125%; 8-45 s at 150%; 3-15 s at 200%; 0.48-2.5 s at 400%. Interrupting rating: 1,000 A at 250V AC; 1,000 A at 65V DC. Terminals: main: M5 stud; auxiliary / alarm: 0.110 in quick-connect tab. Life: 10,000 operations minimum. It operates from -40 to +85 °C. Approvals: UL Recognized (UL 1077), cUL, VDE (EN 60934); UL file E68029.
