Siemens SENTRON Miniature Circuit Breaker 25A, 4-Pole, C Curve, 10kA – 5SL4425-7RCZ12

Product Description

The Siemens 5SL4425-7RCZ12 is a SENTRON Miniature Circuit Breaker (MCB) designed to provide reliable overload and short-circuit protection in electrical distribution systems. It features a 25 A rated current, 4-pole configuration, C tripping characteristic, and 10 kA breaking capacity, making it suitable for three-phase electrical distribution and industrial, commercial, and infrastructure applications. Siemens documentation for the corresponding 5SL4425-7RC variant confirms the 4-pole, C-curve, 25 A and 10 kA configuration.

The MCB is designed for 415 V AC supply and operates at 50/60 Hz. It provides energy limitation Class 3 and IP20 protection with connected conductors. The C-curve characteristic makes it suitable for circuits with moderate starting or inrush currents.

The Siemens 5SL4425-7RCZ12 is suitable for industrial control panels, distribution boards, commercial buildings, machinery, three-phase power distribution systems, and electrical installations.

At SB Smart, Faridabad, we supply genuine Siemens SENTRON MCBs, MCCBs, MPCBs, contactors, overload relays, and industrial electrical and automation products with GST billing, technical support, bulk-order assistance, and delivery across India.
