| Design Of The Product | For motor protection |
Rated breaking capacity hits 100 kA at 240 V, 400 V, and 500 V, dropping to 10 kA at 690 V. The gL/gG fuse coordination values are 25 A at 400 V and 500 V, 20 A at 690 V, so if you do back it with fuses for a higher SCCR, those are the maximum ratings.
Width is 45 mm, depth 97 mm, height 106 mm — that's a single 45 mm module on the DIN rail, leaving room alongside contactors or overloads. Mounting position any, so vertical or horizontal panel layouts work.
This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.
100 kA at 400 V rated value, which means it can interrupt a high-fault bolted short without upstream fuses needing to clear.
CLASS 10 — it trips within 10 seconds at 7.2× rated current, matching standard motor starting curves for most induction motors.
Yes, phase failure detection is built in — a lost phase trips the breaker before the motor single-phases.
