Circuit breaker Schneider Electric NSYGCA46 16A 3P 30mA

The Schneider Electric NSYGCA46 16A 3P 30mA is a compact circuit breaker combining overcurrent protection and residual-current detection in a single device. Designed for distribution panels in residential and commercial buildings, it interrupts power in case of overloads, short circuits and earth leakage, helping to safeguard lighting circuits, socket outlets and small equipment. The unit's three-pole configuration allows simultaneous protection of three phases in multi-phase installations while maintaining a small footprint suitable for standard DIN-rail mounting.

Advantages

This Schneider Electric device integrates thermal-magnetic overcurrent protection with 30 mA residual-current sensitivity, enabling coordinated response to both overload/short-circuit events and earth faults. Its 16A rated current is appropriate for many lighting and socket circuits, and the three-pole design ensures balanced protection across phases. The product's compact dimensions and standard mounting facilitate straightforward installation and space-efficient panel layout. Built to industry safety standards, it provides predictable trip characteristics and reliable operation over repeated fault conditions.

Suitable for

• Protection of three-phase lighting circuits in residential and commercial premises
• Protection of small motor loads and socket groups up to 16A per pole
• Use in distribution boards where combined overcurrent and earth-leakage protection is required
• Replacement or upgrade of existing 3-pole protective devices in mains panels

Key specifications

• Rated current: 16 A
• Poles: 3-pole configuration
• Residual-current sensitivity: 30 mA
• Protection types: thermal-magnetic overcurrent plus residual-current detection
• Mounting: DIN-rail compatible
• Typical applications: three-phase distribution boards for lighting, sockets and small equipment

How to use

Install the circuit breaker on a standard DIN-rail inside the distribution panel, ensuring correct phase and neutral wiring according to local electrical regulations. Connect the supply and load conductors to the designated terminals and tighten terminal screws to the manufacturer's recommended torque. Verify that upstream overcurrent protection and downstream protective devices are coordinated. After installation, perform insulation and continuity checks, and test the residual-current function to confirm a trip at the specified 30 mA sensitivity before placing the circuit into service.

Usage recommendations

Select the Schneider Electric NSYGCA46 16A 3P 30mA where combined protection against overloads, short circuits and earth leakage is required for three-phase circuits. Ensure compatibility with installation wiring, correct breaker rating for connected loads, and adherence to applicable electrical codes. Periodic testing of the residual-current function and visual inspection for signs of wear or damage will support long-term reliability.
