GACIA SB6L B 1P 16A Miniature Circuit Breaker, 1-Pole, 16 A, B Curve, 6 kA Breaking Capacity

The GACIA SB6L B 1P 16A is a miniature circuit breaker (MCB) engineered for dependable protection of low-voltage electrical installations. Its standout capability is the 6 kA breaking capacity, which safely interrupts high fault currents to prevent damage to wiring and connected equipment.

Advantages

This MCB combines robust construction with precise tripping characteristics. The B curve ensures immediate response to short-circuit currents while tolerating normal inrush currents, making it ideal for residential and light commercial circuits. Its compact single-pole design saves space on the DIN rail, and screw terminals accommodate conductors up to 25 mm² for flexible installation.

Suitable for

• Protection of socket outlets and lighting circuits in homes and offices
• Control circuits and small motors with moderate starting currents
• Distribution boards requiring reliable overload and short-circuit protection
• Installations compliant with IEC/EN 60898-1 standards
