SCHELINGER A02-G8-1P-B63 Miniature Circuit Breaker 6kA 1P B 63A VDE

For installations where a 63 A load must be protected without nuisance tripping, the SCHELINGER A02-G8-1P-B63 delivers a B-curve response and a true 6 kA breaking capacity in a compact single-module housing. Unlike generic breakers that soften their magnetic trip under real fault conditions, this unit holds its calibration across the full -25 °C to +55 °C operating window, so motors, heaters and lighting banks start cleanly while short-circuit energy is still limited to class 3.

Highlights

• Rated current 63 A, tripping curve B, 1-pole protected
• Short-circuit breaking capacity 6 kA at 230/400 V AC
• Energy limiting class 3 for reduced let-through energy
• DIN rail mounting on 35 mm EN 60715 profile
• VDE certified, compliant with IEC/EN 60898-1
• Wide terminal range: 1–35 mm² rigid, 1–25 mm² flexible
• 10,000 electrical and 20,000 mechanical operating cycles

In daily use

The A02-G8-1P-B63 is built for distribution boards where space is tight but performance cannot be compromised. Its single-pole design occupies one 18 mm module, yet the terminal capacity accepts large cross-sections up to 35 mm², reducing the need for additional reduction terminals. The B-curve magnetic trip is set to 3–5 times rated current, making it suitable for circuits with moderate inrush currents such as resistive heating, water heaters, and general socket outlets. During a fault, the 6 kA breaking capacity safely interrupts the current without damage to the device, and the IP20 housing (IP40 at terminals) protects against accidental contact while allowing easy inspection and wiring.
