Circuit breaker Schneider Electric WDE015921 16A 1P C single-pole 6 kA

Schneider Electric WDE015921 is a 16A single-pole (1P) circuit breaker with a C tripping characteristic designed for residential and commercial electrical installations. It provides overcurrent and short-circuit protection for lighting circuits, socket outlets and small appliance circuits. The device mounts on standard DIN rails and offers a compact form factor for use in distribution boards where space and reliable protection are required.

Advantages

This single-pole circuit breaker features a C-type trip curve suitable for general-purpose circuits with moderate inrush currents, combining reliable protection against overloads and short circuits with predictable tripping behaviour. Its compact design allows for efficient use of space in distribution panels, while Schneider Electric manufacturing standards ensure consistent build quality and electrical performance. The breaker provides clear manual operation via a toggle lever and is compatible with common DIN-rail accessories for installation and labeling.

Suitable for

• Residential lighting circuits
• Socket outlet circuits for small appliances
• Small commercial branch circuits
• Replacement and new installations in DIN-rail distribution boards

Key specifications

• Rated current: 16 A
• Number of poles: 1 (single-pole)
• Tripping characteristic: Type C
• Interrupting capacity: 6 kA
• Mounting: DIN-rail
• Intended use: overcurrent and short-circuit protection for lighting and general circuits
• Manual operation: toggle switch

How to use

Install the circuit breaker into a compatible DIN-rail distribution board following local electrical codes and safety regulations. Connect the phase conductor to the breaker’s input terminal and the load conductor to the output terminal, ensuring tightened connections and correct polarity. Use the toggle lever to switch the circuit on or off during commissioning and maintenance. Verify correct operation by testing the protected circuit and, if necessary, simulate fault conditions only while observing safe procedures.

Usage recommendations

Choose this 16A C-characteristic breaker for branch circuits with moderate inrush currents such as lighting and small motor loads; avoid using it where specific selective coordination or higher breaking capacities are required. Ensure proper coordination with upstream protection and routine inspection of connections and panel environment to maintain reliable operation.
