Schneider Electric Easy9 Miniature Circuit Breaker (MCB), 3P, 16A, C-Curve, 6kA

The Schneider Electric Easy9 EZ9F57316 is a high-quality miniature circuit breaker (MCB) designed for reliable overcurrent protection in residential and commercial electrical installations. With 3 poles, a rated current of 16A, and a C-curve tripping characteristic, it ensures safe and efficient operation for a wide range of applications.

Advantages

This MCB offers thermal-magnetic protection, combining a bimetallic strip for overload protection and an electromagnetic coil for short-circuit protection. Its compact design fits standard DIN rail mounting, saving space in distribution boards. The tunnel terminals allow easy and secure wiring, supporting flexible cables up to 25 mm² and rigid cables up to 35 mm².

Suitable for

• Overcurrent protection in lighting, socket outlets, and small appliance circuits
• Residential and commercial electrical panels
• Protection of cables and equipment against overloads and short circuits
