Schelinger A02-G8-1P-B20 jistič 6kA 1P B 20A VDE

Electricians and panel builders rely on the Schelinger A02-G8-1P-B20 to protect lighting and socket circuits in residential and commercial installations. This single-pole miniature circuit breaker trips instantly on short circuits and follows a delayed thermal response for overloads, keeping wiring and connected equipment safe. Its compact 18mm width fits standard 35mm DIN rails, making it a drop-in replacement for most distribution boards.

Why choose it

The B-curve characteristic suits general-purpose circuits with moderate inrush currents, such as lighting and socket outlets. The 6 kA breaking capacity handles typical residential and light commercial fault levels, while screw terminals accept a wide range of conductor sizes for flexible wiring. VDE certification confirms compliance with strict European safety standards.

Ideal use cases

• Residential distribution boards
• Office and retail lighting circuits
• Socket outlet protection
• Control panel feeder protection
• Retrofit projects requiring 18mm width

Good to know

Installation requires a standard 35mm DIN rail and a suitable busbar or cable connection. The breaker is not suitable for DC circuits or high inrush loads like large motors; for those, consider a C or D curve. Always verify short-circuit current at the installation point does not exceed 6 kA.
