SCHELINGER A02-G8-1P-B40 Miniature Circuit Breaker 1P B40 6kA VDE

Electrical overloads and short circuits pose serious risks to residential and commercial wiring. The SCHELINGER A02-G8-1P-B40 Miniature Circuit Breaker (MCB) provides reliable protection for single-pole circuits rated up to 40 A. With a B-curve tripping characteristic and 6 kA breaking capacity, it quickly interrupts fault currents, safeguarding cables and connected equipment from damage. This VDE-certified breaker is engineered for DIN rail mounting and meets EN 60898-1 standards, ensuring consistent performance in distribution boards and consumer units.

Who is it for

This MCB is ideal for electricians, panel builders, and maintenance technicians who need a dependable overcurrent protection device for lighting and general-purpose circuits. It suits residential installations, small commercial panels, and industrial control cabinets where a 40 A single-pole breaker with B-curve tripping is specified. DIY enthusiasts with appropriate electrical knowledge will also find it straightforward to install in standard 35 mm DIN rail enclosures.

Tips

Always de-energize the circuit before installation or maintenance. Use a torque screwdriver to tighten terminals to the manufacturer's recommended torque to ensure reliable connections. This breaker is designed for use in pollution degree 2 environments and should be installed in an enclosure providing additional protection against dust and moisture. For circuits with high inrush currents (e.g., motors, transformers), consider a C or D curve breaker instead.
