Product description

The Siemens 5SY4432-7 is a 4-pole miniature circuit breaker (MCB) designed for comprehensive overload and short-circuit protection. It operates at 400V with a 10kA breaking capacity and features a C-curve tripping characteristic, suitable for various electrical systems requiring four-pole switching.

This MCB is ideal for use in industrial control panels, automation systems, and applications where a four-pole configuration is necessary for complete circuit isolation. The C-curve characteristic offers a balance between protection and preventing nuisance tripping for loads with moderate inrush currents.
